The disclosure relates generally to exercise devices. More particularly, the disclosure relates to portable exercise devices, and more specifically, the disclosure relates to portable exercise devices for training the core muscles of the body, and to methods for doing so.
The core muscles of the torso are essential for most activities involving movement. Core muscle strength is required for a variety of sports and particularly for sports in which a club, bat or racquet is swung around the body.
Many exercise devices exist which are suitable for training the core muscles. One example is a rowing machine, with which a user simulates the motion of rowing whilst pulling a handle which provides resistance. Whilst devices such as rowing machines provide suitable pieces of equipment with which to exercise, they are expensive and take up a large amount of space, making them unsuitable for many people. Additionally, some people may travel frequently and therefore they may require equipment which is portable.
If a user adopts a particular (bad) posture during exercise, he or she may become injured and may damage his or her muscles, which can in turn cause the user to experience pain. After sustaining an injury it is more difficult for a user to exercise, even if different muscles are being trained to those which are injured. As such, it is important for a user to maintain a predetermined, correct, posture which reduces his or her risk of becoming injured during exercise. People who have not exercised regularly in the past may be unaware of how to position themselves if he or she wishes to avoid injury, or indeed how to position themselves to get the most effective muscle development. Some of the exercise devices which are currently available require the user to operate the device in a very specific way, which the user may be unaware of.
Low intensity exercise can be beneficial for a wide variety of people with different needs. For example, for a person who is recovering from a previous injury and is undergoing rehabilitation, high intensity exercise can cause the injury to reoccur. As such, he or she may choose to start off with low intensity exercise initially in order to prevent this. Similarly, a person who is currently injured may want to maintain his or her general fitness levels by continuing to perform low intensity exercise which will not affect the injured part of his or her body. It is therefore beneficial to be able to exercise specific muscles or muscle groups, in a controlled predictable way.
Some exercise devices which are currently available only operate within certain limits of resistance to movement and do not provide a big enough variation in difficulty to accommodate for the people of different needs. For example, some devices which operate using weights may not provide a level of exercise which accessible to people who are new to exercising certain muscles or muscle groups. In contrast, certain devices only operate at a level which is not demanding enough for an experienced user to be able to exercise properly.
An exercise device for training the core muscles that addresses at least some of the issues described above is desired.
According to an aspect of the invention there is provided an exercise device for exercising core muscles of a user’s torso. The exercise device comprises a frame, configured to be supported by the user and a radially outwardly facing channel, the channel configured to receive a resistance member. The frame defines an aperture configured to receive a torso of the user and the device is configured to provide a resistance force against which the user can exercise when the device is in use.
The aperture may be partly defined by the frame and partly defined by another component such as a strap or support. The aperture may be defined as a void into which a user can place his or her torso. The aperture may be an open aperture, in that the frame does not completely encompass a user when the device is in use. The frame may have a curved bow shape. The frame may have a convex outer surface that defines the channel. The frame may have a concave and/or padded inner portion adapted to abut or be closely spaced from the user’s torso. The aperture may be about 180 degrees and the bow may extend about 180 degrees about the torso/aperture when the device is in use.
The channel may be discontinuous. The device may comprise a first frame section and a plurality of second frame sections extending radially outwardly from the first frame section. Each of the second frame sections may comprise part of the channel. The device may comprise an upper rail and a lower rail. Each of the upper rail and lower rail may be coupled to a frame member of the device by a joint at a plurality of points along the length of the frame member. The rails and joints may form a discontinuous channel. The upper and rails may militate against a resistance member from becoming dislodged from the channel in use.
The frame may be formed from an outer curve and an inner curve that meet at junctions. The junctions may be at opposite ends of the frame. The frame may comprise one or more struts that join the inner and outer curves. The frame may line in a common plane. In other words, the strut or struts and inner and outer curves may lie on a single, common plane.
The frame may comprise a maximum radius in the range of 200-1000 mm, 200-500 mm, or 300-400 mm. The frame may comprise a maximum thickness, measured substantially perpendicularly to a radius of the frame, in the range of 20-100 mm, 20-50 mm, or 30-50 mm. A maximum radius of the frame may be in the range of 2-50, 2-20, 2-10 or 5-10 times a maximum thickness of the frame, measured substantially perpendicularly to the maximum radius of the frame. The thickness of the frame excludes any handles which may project away from a generally planar nature of the frame.
At least part of the frame, such as the inner and/or outer curve, may be constructed from a curved box section, for example a metal curved box section. A cross-section of the curved box section may be square, or any other suitable polygonal shape such as rectangular, triangular or circular. Where the cross-section of the curved box section is square, the height and width of the square cross-section may be in the range of 20-100 mm, 20-50 mm, or 30-50 mm.
The inner curve may be flexible. A flexible inner curve may allow the device to flex to various body shapes of prospective users.
The device may be substantially symmetrical across a sagittal plane and/or a transverse plane of the user’s body when the device is held in a use position by the user.
The curved bow shape may be formed along an arc of 120° or more. The aperture may be formed between a corresponding arc of 240° or less.
The device may comprise a thoracic support adapted in use to engage the front of the user’s torso. The device may comprise a lumbar support adapted in use to contact the back of a user. One or both of the thoracic support and the lumbar support may be padded.
The device may comprise a closure strap that in use extends from the ends of the bow shaped frame behind a user, and may be attached to one or both ends of the bow. One or both of the attachments between the strap and the bow may be releasable attachments. One attachment may be a fixed attachment and the other may be a releasable attachment. The closure strap may be adjustable in length. The closure strap may have the lumbar support on it. The lumbar support may be attached to the closure strap or formed within it.
The resistance member may be attachable or attached to one end of the bow.
The resistance member may be attachable or attached to a centre point of the bow.
A pair of resistance members may be provided, or more than two.
The resistance force may be provided as a tangential force. Using a tangential force can provide the user with a uniform and/or controllable force. This can help a user with form and technique and prevent a user from ‘cheating’ by varying arm position or resistance during an exercise movement.
The resistance force may be configurable by the user. This can allow the user to increase or decrease intensity of exercises accordingly. It can also allow the device to be used by both physically stronger and weaker users.
The exercise device may be light weight and may have a mass of less than 10 kg. The exercise device may be readily picked up by a user and be transportable.
The aperture may have a diameter of between 30 cm and 130 cm. The aperture may be sized to fit a range of human torsos. Various iterations of the device may have varying aperture sizes in order to be used by different target users.
The channel may be situated at, proximal to, or radially inwardly displaced from a perimeter of the frame.
The channel may have a depth that is about 50% as deep as the diameter of the resistance member, or deeper; or about as deep as the diameter of the resistance member or deeper; or of at least twice the diameter of the resistance member, and preferably at least four times or six times.
Having a channel depth greater than a diameter of the resistance member reduces the chances of the resistance member being displaced from the channel. A deeper channel can further reduce the chances of displacement.
The frame may lie on a plane and the channel may extend at one or more points in a direction transverse to the plane. Extending the channel may broaden or deepen or both and broaden and deepen the channel. Broadening and/or deepening the channel can mitigate the resistance member coming unseated from the channel. The broadening may also militate against any rebound of the resistance member should it become detached. This may prevent against the resistance member ‘twanging’ and potentially striking the user. The extension or extensions to the channel may comprise ‘anti-twang’ clips or shields. The clips or shields may be releasable components that are releasably attachable to the frame.
The ‘anti-twang’ clips or shields may extend 5 cm, 10 cm or more transverse to the plane of the frame and may optionally extend substantially equidistantly above and below the plane of the frame.
The aperture may have a central axis that is collinear with a central axis of the frame.
Aligning the axes may provide an ergonomically preferable stance to the user and may also provide improved posture and alignment of the users limbs when exercising with the device.
The exercise device may further comprise handles for providing a device supporting means to the user.
The exercise device may comprise multiple sets of handles, and/or handles that are adjustable relative to the frame, to provide differing hand/arm position for the user when the device is in use.
The frame may define one or more slots that face in a downwards direction when the device is in use. The slots may be configured to receive the handles. The slots may be curved slots. The curved slots may follow the curve of the frame. The handles may be angularly movable within the slots. The handles may be securable at a plurality of positions within the slots. Securing the handles at a position within the slots may comprise locking the handles in place in a position that is appropriate for the user to hold and support the device.
The handles may be positioned on the inner or the outer curve.
Providing multiple handles, or adjustable handles, may allow different users to use the device (for example users having differing arms spans). It may also provide a user with the option to vary his hand position in order to enact different exercise movements.
The frame may lie on a plane and the handles may extend transversely to the plane. Having the handles perpendicular, or otherwise angled to, a plane of the frame may provide a more ergonomic position for the users hands and/or arms.
The handles may be radially outwardly displaced from the aperture.
The frame may comprise a plurality of releasably attachable sections.
Having releasably attachable sections may provide the device with a means for it to be dismantled for storage and/or transport. It may also provide a means for sections of the device to be swapped or modified. For example a size of the aperture may be modified by providing various inner sections that define different sized apertures in order to fit different user body types and sizes.
The exercise device may comprise an attachment point for attaching the resistance member to. The exercise device may comprise a plurality of attachment points for attaching the resistance member to.
The exercise may comprise an attachment point for attaching the resistance member at a first end of the bow.
The exercise may comprise an attachment point for attaching the resistance member at a second end of the bow.
The exercise may comprise an attachment point for attaching the resistance member to at a centre point of the bow.
A plurality of resistance members may be used with a plurality of attachment points. A plurality of resistance members may be used with a single attachment point. Using multiple attachment points and resistance members may provide a user a means to alter a twisting direction without reconfiguring the device, providing a means to vary exercises and ensure balanced work-out routines.
The attachment point may be a hole (through which the resistance member could be passed and tied or restricted by), a strut (around which the resistance member could be tied or a clip/carabiner or the like of the resistance member could be clipped) or a clip or carabiner or the like (which could attach to a corresponding loop, clip or the like of the resistance member).
When in-use, a portion of the resistance member may be seated in the channel.
The resistance member may be seated in the channel along an arc of 90° or more.
Seating the resistance member may provide a tangential relationship between the exercise device and a resistance point, and therefore a tangential resistance force.
The exercise device may comprise the resistance member.
The resistance member may be attached to the frame or another structural part of the device.
The resistance member may comprise a cable (band, strap, rope, or other elongate apparatus) configured to be connected to the frame and further configured to be connected to a resistance point.
The cable may be in the form of a steel rope cable commonly found in commercial gym exercise equipment, or may be of lower gauge. A band may be elasticated.
The resistance member may have a length that is greater than half of a length of a perimeter of the frame. The resistance member may have a length that is greater than 1x, 1.5x, or 2x, or 2.5x, or 3x the length of a perimeter of the frame. This may allow the resistance member to be seated in the channel for a full exercise movement of the user when the user is using the device.
The resistance member may be inextensible. The resistance member may be attached to an external resistance providing apparatus when in use to provide the resistance force.
The resistance member may be extensible. Extension of the resistance member may provide the resistance force.
The device may comprise an indicator to provide a user of the device with information relating to their use of the device. The indicator may comprise a spirit level which enables a user to maintain a given angle of the device relative to the horizontal. The indicator may comprise a rep counter which informs a user of the device of a number of completed repetitions of a particular exercise. The indicator may provide a user of the device with information relating to a force or tension applied to the resistance member. The indicator may comprise an electronic display, such as an LCD screen, or one or more lights, such as an LED, configured to provide a user of the device with information. The indicator may comprise a speaker to provide information to the user in the form of sound. The indicator may comprise an accelerometer, gyroscope or any other suitable sensor or means to determine the motion of the device. The device may comprise mounting and/or attachment means for mounting or attaching an electronic device, such as a mobile phone, tablet or the like, the device. The device may utilise sensors within the electronic device to determine motion of the device in use. This information may be provided to a user of the device by means of a screen and/or a speaker of the electronic device.
The mounting means may comprise a pocket, slot, housing, or holster for the device - such as a phone. The pocket/holster/receiving slot or housing may in use receive the device/phone and hold it securely and rigidly to the device so that it moves with the device and so that movement of the so-mounted phone/electronic device equates to movement of the exercising device.
In an example use case, the indicator may comprise an LED and a speaker. A user of the device may provide an input to a controller of the device which is indicative of a particular exercise the user wishes to perform. The LED may flash red if the user is performing the exercise incorrectly. The LED may flash green and the speaker may emit a reassuring sound, such as a ‘swoosh’, if the user performs the exercise correctly.
The device may comprise digital control units located in the frame and in the handles. The digital control units may provide a feedback mechanism for the motion of the device which would specifically give the user a report on the use of the device in operation. This reporting for example may include the amount of resistance being applied in operation of the device and the orientation of the device in respect to the angle of use and the path motion of use. The device may be configured to dynamically control the amount of resistance when used with a cable system which supports the appropriate digital technology to provide this capability. The device handles may be configured to control resistance by way of buttons e.g., a “Smart Handle” with Bluetooth functionality giving the user the ability to turn the resistance on/off or increase/decrease resistance.
Another aspect of the invention provides a kit of parts. The kit of parts comprises the exercise device of the preceding aspect, a resistance member and a set of instructions for providing a user with methods of using the device.
Another aspect of the invention provides a method of exercising core muscles of one’s torso. The method comprises situating a frame about one’s torso and supporting the frame with one’s hands, applying a tangential force to the frame, and turning through an angular distance to enact a resistance force against the tangential force.
Another aspect of the invention provides a method of exercising core muscles of one’s torso. The method comprises taking the exercise device of the first aspect, attaching one end of a resistance member to the exercise device, attaching another end of the resistance member to a resistance point, putting the device overhead and positioning it around one’s torso, positioning oneself so that there is tension in the resistance member, twisting one’s torso against the tension so as to exercise the core muscles of one’s torso.
Attaching another end of the resistance member to a resistance point may comprise attaching the resistance member to an exercise machine comprising a weight and pulley system.
According to another aspect of the invention, there is provided an exercise device for exercising a user’s core muscles, the exercise device comprising: a frame, wherein the frame defines a central aperture configured to receive a torso or trunk of a user; and an attachment point wherein the attachment point is configured to attach the frame to a resistance member in order to provide a resistance force against which the user can exercise when the device is in use.
The exercise device may be configured such that, in use, the resistance force is provided as a torque about a rotational axis of the frame in response to the twisting or turning his or her torso.
The torque may be a configurable torque. On other words a magnitude of the torque may be adjusted. The direction of the torque can also be reversed so as to exercise difference muscle groups and sides of the user’s body.
The torque may be configurable by adjusting a moment of inertia about a central axis of the device, or by changing the resistance of the resistance member, or by changing a resistance provided by a resistance point to which the resistance member is attached (such as a conventional pulley weight type exercise machine).
The device may further comprise fasteners which are configured to attach a first frame section to a second frame section.
The fasteners may be adjustable fasteners which are configured to vary a diameter of an inner frame section, wherein the inner frame section defines the aperture. The fasteners are adjustable through having a length that is variable, such as through a turnbuckle, strap or ratchet system.
The moment of inertia of the exercise device about the central axis of the device may be adjustable.
The frame may comprise receiving means configured to support a resistance member. That is the receiving means can both receive and support the resistance member. The receiving means may be in the form of a channel. The receiving means reduces the likelihood of the resistance member from coming unseated from the exercise device when in use as the resistance member is kept support by the receiving means.

The exercise device may comprise multiple attachments points, wherein the multiple attachment points are configured to be attached to the first end of the resistance member. The multiple attachment points may also form the receiving means in that the attachment points also attach a top section of the frame to a bottom section of the frame and the resistance member can be supported against the attachment points when the resistance member is under tension when in use.
According to another aspect of the invention there may be a kit of parts, the kit of parts comprising an exercise device according to the first aspect, and a resistance member.
The device may be configured such that when a resistance member is attached to the frame, the resistance member provides a resistance force. The resistance force may increase and decrease in response to the user twisting the exercise device. The resistance force may be applied in a direction which is substantially tangential to the perimeter of the frame. The resistance force may be applied in a direction such that a component of the force acts in a direction which is tangential to the perimeter of the frame. The resistance force may provide a torque. The torque may be generated in a direction opposite to that in which the user rotates. The user resists (i.e. provides an opposing torque to) this torque as a means of exercise. The user twists against this torque as a means of exercise.
The frame may comprise multiple attachment points. The different attachment points may be used by a user to provide exercise at different intensity levels. The resistance member may be configured to be attached to the different attachment points in order to produce different torques for the user to exercise against. The resistance member may be configured to be attached to the different attachment points in order to allow the user to exercise different muscle groups.
The frame may be configured such that an axis of rotation of the frame aligns with a central axis of the user during exercise. The frame may be configured to ensure that the user maintains a correct posture whilst exercising. The term correct posture is used throughout this application to refer to a stance during exercise wherein a user minimises his or her chance of sustaining an injury.
The frame of the exercise device may have the shape of a circle. The frame of the exercise device may have the shape of any regular polygon, any ovoid or conical section, or any irregular polygon any other irregular shapes, such as a pear shape.
The frame may comprise an inner diameter and an outer diameter. The inner diameter may be defined by the size of the central aperture of the frame. The outer diameter may define the overall radial extent of the frame.
The inner diameter of the frame may range between 40 cm to 100 cm, or 50 cm to 90 cm, or between 60 cm to 80 cm. The inner diameter of the frame may be adjustable. The inner diameter of the frame may adjustable to enable a variety of different users to fit within the central aperture of the device.
The outer diameter of the frame may range between 70 cm to 120 cm, or between 80 cm to 110 cm, or between 85 cm to 105 cm. The outer diameter of the frame may be no greater than 10 cm wider than an average user’s arm span.
The frame of the exercise device may comprise a single frame section. The frame of the exercise device may comprise a plurality of frame sections. The frame sections may be held together via adjustable fasteners. The frame sections may be held together via rigid fasteners. The frame section with the smallest diameter may be referred to as the innermost frame section. The frame section with the largest diameter may be referred to as the outermost frame section.
The frame may comprise a first frame section and a second frame section. A diameter of the first frame section may be smaller than a diameter of the second frame section. The first frame section may define the inner diameter of the frame. The second frame section may define the outer diameter of the frame. The first frame section may be the innermost frame section. The second frame section may be the outermost frame section.
The innermost frame section may be configured to fit proximally around the waist of a user. The term “proximally” in this context means there is a gap between the user’s waist and the innermost frame section. The gap between the user and the innermost frame section may range between 0 cm and 30 cm, or between 0 cm and 20 cm, or may range between 0 cm and 10 cm.
The attachment point may be attached to or formed as part of the outermost frame section. The attachment point may be attached to or formed as part of the innermost frame section. Multiple frame sections may have an attachment point attached to or formed as part of them. There may be multiple attachment points on each frame section.
The attachment point may be configured to have the resistance member tied around it. The attachment point may be configured by comprising a projecting rod around which the resistance member can be tied without the subsequent knot slipping off, such as by terminating ends of the rod into the frame. The attachment point may be configured to support a hook which is attached to the resistance member. The attachment point may be configured such that the resistance member can clip on to the frame of the exercise device. The attachment point may be configured to limit the motion of the resistance member from sliding around the frame of the exercise device. The attachment point may be configured to reduce the chance of the resistance member becoming detached from the frame when compared with a device which does not have an attachment point. The attachment point may be configured to have the resistance member attached to it through the provision of corresponding features on the resistance member and the attachment point, such as the attachment point comprise a clip (such as a carabiner) and the resistance member comprise a closed loop, or vice-versa.
A user may selectively connect the resistance member to a particular frame section in order to select a desired resistance torque to exercise against.
The component of the resistance force which acts in a tangential direction to the perimeter of the frame creates a moment about the centre of rotation of the device. This moment is proportional to the distance between the centre of rotation and the position at which the force is being applied. As such, the attachment points to which the resistance member may be attached provide a greater moment, and hence a greater torque for a user to exercise against, when he or she is positioned further from the centre of rotation of the device. The device enables the resistance member to be attached at differing radii in order to provide differing torques to the user.
The resistance member may apply a rotational force to the frame consistently around the entire perimeter of the frame. The resistance member may apply a rotational force along a continuous section of the frame. The resistance member may apply a rotational force to the innermost frame section. The resistance member may apply a rotation force to the outermost frame section. The resistance member may apply a rotational force to a frame section which does not comprise the attachment point. The resistance member may be attach to the frame via an attachment point on the first frame section and apply a rotational force to the frame via the second frame section or vice versa.
The exercise device may comprise handles. The handles may be positioned on the frame. The exercise device may alternatively comprise detachable handles. The detachable handles may be configured to be attached to or detached from the frame. The term “handles” used throughout the application may now refer to either permanent, or detachable handles. The exercise device may comprise a plurality of handles at varying distances from the centre of the device. Having detachable handles may provide a more compact storage and transport solution as well as allowing a user to position handles according to his or her preference/ according to an exercise requirement.
The handles may be positioned on the innermost frame section. The handles may be positioned on the outermost frame section. There may be handles on any of the frame sections. There may be handles positioned on multiple frame sections at the same time. There may be handles positioned at different distances from the centre of rotation of the device. The handles positioned on different frame sections may be configured to enable the user to exercise different muscles or muscle groups. The handles positioned on different frame sections may be configured to enable the user to vary the intensity of exercise he or she experiences. The handles may be positioned at various distances from the centre of the device so that users with different arm spans can reach the handles.
The handles positioned on the outermost frame reduce the force a user needs to apply to rotate the device. The handles positioned on the innermost frame sections increase the force a user needs to apply to rotate the device.
The force which the user may apply via the handles creates a moment about the centre of rotation. The moment is proportional to the distance between the centre of rotation of the device and the position at which the force which creates the moment is applied. As such, the user can apply a greater moment to the device whilst applying the same force by applying the force using handles which are positioned at a greater distance from the centre of rotation of the device.
The exercise device may comprise attachment points at various positions relative to the handles of the device. The attachment points at various positions relative to the handles may be configured to allow a user to exercise different muscles or muscle groups.
The or each handle of any of the above described embodiments may comprise two upright sections and a transverse section extending between the upright sections. The or each handle may be attached to the frame at a first end of each upright section. The or each handle may be substantially U-shaped. The angle between the transverse section and each of the upright sections may be substantially a right angle. Each upright section may extend substantially perpendicularly to the plane of the frame, or each upright section may extend at an angle of less than or greater than 90 degrees to the plane of the frame.
Providing a handle with multiple connection points with the frame, i.e. via the upright sections, may increase the stability of the handle. In addition, the fastening load at each of the connection points would not be required to be as great compared to a handle comprising a single connection point. Such a handle also provides multiple grip positions with a single handle, such as an overhand or underhand horizontal grip on the transverse section, or a vertical grip on the upright sections.
The exercise device may comprise straps attached to the frame. The straps may be configured to attach the device to the user. The straps may be configured to suspend the device from the body of the user. The straps may be configured to be worn over the shoulders of the user.

The user may choose from one of the plurality of resistance members in order for the device to provide a desired torque against which the user can exercise. The resistance member may be configured to wrap around the outer perimeter of the frame multiple times to increase the tension throughout the resistance member, which would increase the torque against which the user exercises. A plurality of resistance members may be attached the frame at the same time. A plurality of resistance members may be attached to a plurality of different attachments points at the same time. A plurality of resistance members may be attached to the same attachment point at the same time.
The frame may comprise a receiving means in the form of a channel configured to receive the resistance member attached to the frame. The receiving means may prevent the resistance member from losing contact with an outer perimeter of the frame. The receiving means may be configured to support the resistance member. The receiving means may be a receiving groove. The receiving means may be present along all or most of an outer perimeter of the frame. The receiving means may prevent the resistance member from slipping off the frame and hitting the user.

The stationary resistance point may be a wall, a floor, or an object which is sufficiently heavy such that it will not be moved by a force from the resistance member. The resistance member may comprise a loop of clip in order to be retained by the resistance point or may be simply tied and/or knotted around the resistance point (such as when the resistance member comprises a rope or band).
The resistance point which may be attached to the second end of a resistance member may be a moveable resistance point. The moveable resistance point may be a pulley weight system. The resistance point may be attached to a system such that the resistance member is configured to apply a variable force to the device. The user may increase the weight on the pulley weight system in in order to experience a greater torque to exercise against. The resistance point may be an exercise device already known in the art.
The user may attach the second end of the resistance member to a pulley weight system, and in this situation, the user may use a non-stretchable resistance member. The device may be configured to be used in combination with pre-existing devices. The user may vary the weight system in order to increase or decrease the tension throughout the resistance member. The user may increase or decrease the tension throughout the resistance member in order to experience a different amount of torque to exercise against.
The user may stand closer or further away from the resistance point in order to increase or decrease the tension throughout the resistance member. The user may choose to wrap the resistance member around the outer perimeter of the device a multiple number of times in order to increase the tension throughout the resistance member.
The user may rotate in a first direction to exercise a first group of muscles, and may rotate in a second direction to exercise a second group of muscles. The user may use the device whilst in a standing position in order to exercise. The user may keep the device substantially perpendicular to his or her upper body whilst exercising. The user may rotate the device by rotating his or her upper body only. The user may rotate the device by rotating his or her arms relative to his or her body. The user may rotate his or her body forward at the hips or knees whilst using the device in order to strengthen the specific muscle groups associated with swinging a racket, club or bat. The user may use the device in various positions in order to exercise different muscle groups.
A pendulum, or swinging member, may be provided for use with or as part of the exercise device. The pendulum may be provided instead of or in addition to a resistance member. The pendulum may be configured to swing when the user rotates the device using their core. The forces exerted by the pendulum on the user may further condition or strengthen core muscles, and train the user. The pendulum may oscillate in use and a user’s attempt to control the oscillation, when the device is in use, may provide guidance to the user for improving his or her form (wherein form may refer to exercising in a particular way and/or in a way that is in imitation of performing a particular sporting action - such as a golf swing).
The device may be configured to predominantly exercise the user’s core muscles during exercise. The device may be configured to also exercise other muscles groups during exercise.
The device may be configured such that if the user accidently releases the device during exercise, it will not be repelled towards the resistance point to avoid someone being injured or something being damaged.
The use of the term “diameter” throughout the description and claims should be taken to mean the widest point when referring to a non-circular feature.
According to another aspect of the invention there may be a kit of parts, the kit of parts comprising an exercise device according to the first aspect and a stability training device. The stability training device may be of the type that a user stands on in use. The stability training device may be designed to be deliberately unstable when a user is standing on the stability training device, so as to train the core muscles of the user as the user attempts to maintain stability. The stability training device may comprise a board or a cylinder or curved surface for standing on, and the stability training device may be compressible, for example a compressible cellular or foam structure..
Examples of the invention will now be described, with reference to the accompanying drawings, in which:
In each of the prior art exercise machines 10, 20 the user is provided with control over the positioning of his or her hands and arms relative to his or her body. Whilst this freedom can provide for a variety of exercises to be performed it can also lead to injury or ineffective exercises due to poor technique and body positioning.
An example of an exercise device 100 for improving core strength is shown being used in the photograph of
A simplified, plan view of the exercise device is shown in
The frame 110 comprises a first frame section 116 and a second frame section 118. The second frame section 118 has a greater outer diameter than the first frame section 116. An inner diameter of the first frame section 116 defines an inner diameter of the frame 110. The outer diameter of the second frame section 118 defines an outer diameter of the frame 110. The first frame section 116 and the second frame section 118 share a common central axis. In this example, in which the first and second frame sections are circular, the first frame section 116 and the second frame section 118 are therefore concentric. In other examples, the frame may comprise only a single frame section or any multiple number of frame sections. In other examples, the frame sections 116, 118 may not share a common centre.
The frame 110 is substantially circular. The first frame section 116 and the second frame section 118 are also substantially circular. In other examples the frame 110 may have another shape, such as any regular polygon or any irregular polygon, a conic section or a pear shape. Different shaped frames 110 may be used in order for the user to exercise different muscles or muscle groups with the device.
The inner diameter of the first frame section 116 is configured to be greater than the girth of a user, such that the user can fit his or her torso within the central aperture 112 of the frame 110. The outer diameter of the second frame section 118 is not too large so that the user can reach the second frame section 118 when he or she is positioned within the central aperture 112.
The first frame section 116 and the second frame section 118 are attached together via a plurality of fasteners 120.
The first frame 116 section may comprise an elastic ring. The elastic ring may be constructed such that it has a diameter which is large enough to fit proximally around the torso of the user when there are no forces being exerted on it. The elastic ring 116 may be configured such that its diameter increases when there are forces being exerted on it via the fasteners 120. The fasteners 120 may be adjustable fasteners, and may be adjusted in order to adjust the force exerted on, and the inner diameter of, the elastic ring 116. The elastic ring 116 may be configured such that its diameter can be increased and/or decreased to a size at which it can fit proximally around the torso of users with various girths.
The frame 110 and its components (116, 118, 120) can be made from any suitable material such as plastic, wood, or metal. The materials used are sufficiently strong so that he or she does not significantly bend or deform under his or her own weight or when in use. The materials are lightweight so that a user is able to lift the device 100 without great effort. The frame 110 may be constructed using hollow tubes in order to reduce its weight. In this example the frame 100 and its components are formed from a polymer. Each part is formed from polyethylene. More specifically the outer frame section 118 is formed from high-density polyethylene and the other components are formed from low-density polyethylene. Different materials may be used in dependence on design criteria and the envisaged end user. For example, a device designed for an adult to use may be stronger (and potentially heavier) than a device designed for use by a child. Lightweight materials are preferred, having sufficient structural rigidity for the frame sections (plastics and metal, e.g. aluminium, for example).
The handles 114 provide a grip for the user. The handles 114 may be profiled or coated with an appropriate material, such as rubber, in order to provide comfort for the user when grasping the handles 114. In the present example, the handles 114 are shown as protrusions extending from the second frame section 118. However, in other examples, the handles may be integrally formed as part of the frame 110. The handles 114 may be formed from indents in the frame sections (116, 118) which are configured to receive the user’s fingers. The handles 114 may be constructed from, or coated with, a material which increases the grip a user can get on the handles 114.
The resistance member may be supplied separately or with the frame 110 of the exercise device 100 and be attachable to the frame. The resistance member 142 may be formed integrally with the frame 110 in other examples. A first end of the resistance member 142 is attached to the frame 110 via an attachment point 140. In other examples, there may be multiple attachment points. In this example the attachment point 140 is positioned on the second frame section 118. In other examples, the attachment point(s) 140 may be positioned on the first frame section. Having multiple attachment points allows for the position of the resistance member relative to the user to be modified. This can allow for further configuration in order to account for different exercise regimes. The attachment point (or attachment points) may also be re-positionable on the frame as an alternate or supplementary means to provide further configuration options. The attachment point may be re-positionable using a clamping means, by which the attachment point clamps to the frame, or by any other suitable, releasable attachment means. Various attachment points are envisaged. The attachment point used is configured to be co-operable with the resistance member and/or vice-versa. For example, a hook-and-eye system may be used, in which the resistance member comprises a loop (i.e. the eye) at a first end and the attachment comprises a hook, peg, or similar, over which the loop may be secured. The attachment point may comprise a clamp, configured to be releasably clamped onto the first end of the resistance member,
In this example, the resistance member 142 is a stretchable member, such as an elastic resistance band. The resistance force to the user twisting his or her torso is provided through stretching the resistance member. The strength required of the user to exercise with the member being proportional to the spring constant of the resistance member 142. In other examples, the resistance member 142 may be a relatively inelastic resistance cable (i.e. one that is not meant to be stretched during use), for example a steel or nylon cable such as steel wire rope often used in fixed gym equipment. In these examples resistance is generally not provided by the resistance member, but through a system (e.g. a weight or separate spring) to which the resistance member may be attached at its second end.
The second end of the resistance member 142 is configured to be attached to an external resistance point. The external resistance point may be stationary, fixed point such as a wall, a floor, a post, or a door handle (on a closed door) or may be a dynamic resistance point such as a pulley weight system. For an exercise device using a stretchable member a fixed resistance point is used. For an exercise using an in-elastic resistance member a dynamic resistance point is used.
The resistance member 142 may be wrapped or partly wrapped around the perimeter of the frame 110 when the device is in use or when in storage. The resistance member may be wrapped around the second frame section 118 once or any number of times. Wrapping the resistance member around the device can be used to increase the tension throughout the resistance member. Wrapping the resistance member around the device also provides a storage means, by which the resistance member can be kept with the frame 110 for improved storage and transportation (compared with keeping the resistance member 142 separate from the frame 110). Wrapping the resistance member around the perimeter of the frame may apply an inwardly directed force (i.e. towards the central axis of the device) which may also assist the resistance member with locating on the device and reducing the likelihood of the resistance member becoming unseated from the device during use.
The exercise device 100 comprises a receiver which is configured to receive the resistance member 142 when the resistance member is wrapped around the frame 110. The receiver is comprised within the frame 110 in this example. The second frame section 118 comprises connecting rods (not shown in
The top section 122 and the bottom section 124 of the second frame section 118 are connected via the connecting rods 126. The connecting rods 126 can be curved, such that the centre of the connecting rods 126 (the centre being the point midway between the top section 122 and the bottom section 124) is closer to the centre of the exercise device 100.
The connecting rods may be constructed from any suitable material which will not break under the inwardly (i.e. towards the central axis of the frame) directed force exerted by the resistance member 142. In the example shown, the top section 122 and bottom section 124 of the second frame section are hollow In other examples the top section 122 may be hollow and the bottom section 124 may not be hollow, or vice versa. In other examples, the top and bottom sections 122, 124 may both be solid throughout.
The curvature of the connecting rods 126 creates a channel which provides a receiving means in which the resistance member 142 is received. In this example, the channel 130 is formed by the groove. In other examples, the receiving means 130 may be a receiving tube or other receiver. The channel 130 prevents the weight of the resistance member 142 from causing the resistance member 142 to fall away from the second frame section 118.
The connecting rods 126 may also be used as an attachment point to attach the resistance member 142 to the device 100. In such examples, the first end of the resistance member 142 can be tied around one of the connecting rods 126 in order to connect the resistance member 142 to the exercise device 100.
In other examples the channel 130 may be constructed from a single section. The single section may be of semi-circular cross section wherein the centre of the cross section curves towards the centre of the frame 110. The semi-circular cross section may be configured to support the resistance member 142. In other examples, the single section may be of circular cross section (i.e. a tube) configured to contain a portion of the resistance member 142.
The first frame section 116 (shown in
The user 150 in
The user may use different resistance members 142 to increase or decrease the tension throughout the resistance member 142. The user may use a resistance member 142 with a shorter natural length in order to increase the tension throughout the resistance member 142 without having the stand in a different position. In contrast, the user 150 may use a resistance member 142 with a greater natural length in order to decrease the tension throughout the resistance member 142 without having to stand in a different position.
Further, the user 150 may use a resistance member 142 with a greater spring constant in order to increase the tension throughout the resistance member 142. In contrast the user 150 may use a resistance member 142 with a smaller spring constant in order to decrease the tension throughout the resistance member 142. The user may choose to increase or decrease the tension throughout the resistance member 142 in this way in order to vary the intensity of exercise he or she experiences.
In
The component of the resistance force which acts tangentially to the perimeter of the second frame section 118 creates a clockwise torque, indicated by the arrow 152. The user 150 resists against this torque and uses it as a means of exercise. The user 150 may twist in an anti-clockwise direction to increase the amount of torque being applied or reduce the torque through twisting clockwise. As the user twists through a greater angle, the torque applied to the device 100 increases. In this example the user twists between the positions shown in
In order to exercise the other side of his or her body the user can turn the other way from the starting position shown in
By twisting it is meant that the user keeps his or her feet in position or at least does not move his or her position much, and the movement comes from turning of the torso. Such actions are common in many sports, particularly sports which involve striking - such as golf, hockey and racquet sports.
The user 150 may twist in clockwise and anti-clockwise directions periodically as a means of exercise. The user 150 may rotate through small angles to repeatedly exercise a specific muscle group. The user may rotate through larger angles to exercise a wider variety of muscle groups.
In other examples, the user 150 may rotate clockwise from the starting position. In such examples, the torque which the user 150 exercises against would then be in an anti-clockwise direction.
In some situations the user may turn the device through an angle greater than 360° in order to get into a starting position. In such a situation, the resistance member 142 will wrap around the perimeter of the second frame section 118. As the user 150 rotates, the resistance member 142 may be supported within the channel 130. The channel may decrease the chance of the resistance member 142 losing contact with the second frame section 118 than if the resistance member simply wrapper around a perimeter of the device.
In the examples shown in
In other examples, the resistance member 142 may be non-extendable and the resistance point 144 may be a pulley weight system. Examples are shown in
As the user 150 rotates the device 100, the attachment point 140 moves the resistance member 142 via the first end of the resistance member 142. The second end of the resistance member 142 is attached to the pulley weight system 144. As the user rotates, the resistance member 142 exerts a force on the pulley weight system 144 in order to lift a set of weights. The user may periodically rotate clockwise and anti-clockwise in order to repeatedly lift the weights as a means of exercise.
The non-extendable resistance member 142 is made from a material which is sufficiently strong to avoid it snapping when a large force is imposed on it from the pulley weight system.
When a force is applied to the first frame section 116 as indicated by arrow A, the moment produced about the centre of the rotation 102 of the device 100 is given by the equation: Moment = d1 × Size of force A. Similarly, When a force is applied to the second frame section 118 as indicated by arrow B, the moment produced about the centre of the rotation 102 of the device 100 is given by the equation: Moment = d2 x Size of force B. As such, the same moment can be applied by applying less force when the force is applied to the second frame section 118 rather than the first frame section 116. Similarly, the same moment can be applied by applying a greater force when the force is applied to the first frame section 116 rather than the second frame section 118. A user may use handles and/or attachment points positioned on the various frame sections according to this principle.
The adjustability may also provide the option to position the device to exercise different muscle groups.
In
In some examples the device is not used with an external resistance point in order to provide a resistance torque. Instead, a user can simply exercise against a moment of inertia of the device. In order to vary the moment of inertia the resistance member can be provided to increase mass rather than to be fixed to an external resistance point. Such an example is shown in
Another example of an exercise device 500 is shown in
The channel 530 is extended in at least one area to offer more protection to the user in case of accidental disconnection of the resistance member 142. The extension is provided through the addition of at least one releasably attachable shield 540. The shield is substantially concave to locate the resistance member in the same manner as the channel 530. The shield 540 extends vertically in both directions to provide protection in either direction. There are preferably a plurality of shields, at least one for each of the left and right sides of the device 500. Each shield 540 clips into a hole 570 formed in the frame 510. The holes 510 also provide light weighting to the device and walls of the holes provide stiffness to the device 500. Adjustable handles 514 are provided for the user to grip when the device 500 is in use.
The frame 510 has a pad 550 attached to it. The pad 510 sits opposite to the cushioned section 591 of the support strap 590 when in use. The pad 550 is a thoracic pad in that is it is a pad that engages with the torso of the user when in use. In use, a user may position the device 500 such that pad 550 is adjacent to the front of the user’s torso. The user may then close the aperture 512 by means of the support strap 590, such that the cushioned section 591 of the support strap 590 is adjacent to the rear of the user’s torso. Alternatively, the device 500 may be operable with the pad 550 adjacent to the rear of a user’s torso. The aperture 512 does not necessarily have to be closed by means of the support strap 590 in use - the user may just put the device around the front of their torso, possibly with the pad between their torso and the frame of the device, with nothing behind their back. This may be quicker an d easier to do than to pass straps behind them. In some embodiments, the support strap 590 may not be present.
In addition or alternatively to the frame pad 550 and the cushioned section 591 of the support strap 590, the frame 510 may comprise further padding. For example, padding may be provided on inner surfaces of the frame 510 which could come into contact with a user if the device 500 in use, such as at the edges of the inner section of the frame 510.
Mode detail regarding the pad 550 is shown in
The handles 514 and their adjustment means are shown in more detail in
In some embodiments, the handle 514 may comprise a longitudinal threaded bore to receive the bolt 516. In this way the handle 514 may be removed from the frame 510 by tightening the collar 515 to close the gap 519, thereby gripping the collar 515 against the frame 510 and holding the bolt 516 in a stationary position, before rotating the handle 514 about its longitudinal axis so as to loosen the handle 514 from the bolt 516. The handle 514 can be reattached by receiving the bolt 516 in the longitudinal threaded bore of the handle 514 and rotating the handle 514 about its longitudinal axis so as to tighten the handle against the bolt 516.
Removability of the handle 514 allows interchangeable handles to be used with the frame 510. For example, a plurality of different handles may be provided. Each handle may comprise a different grip or different dimensions. The handles can be interchanged by removing a currently attached handle from the frame 510 before attaching a different handle. The interchangeable handles enable the exercise device to be used by different users with different preferences in terms of grip and handle dimensions, and/or for training for different sports with different requirements.

Various configurations of the device can have one, two, or all three of the above described attachment points. The device can be supplied with one or two resistance members so that the user can use the device with one or two resistance members as preferred.
In another example the device may be fitted with a pendulum or swinging member 600 or similar. The pendulum 600 is attached to the frame of the device at one end and is configures to freely swing in at least one plane and preferably is completely free to swing and not restricted to any particular direction. In the example shown in
The motion of the pendulum can be controlled by the user of the device when the device is in use. It is envisaged that the user can take a golf-like stance and use the device to improve their golf swing technique. Smooth twist movements from the user will allow for the pendulum to be controlled smoothly and its oscillation to be likewise controlled. Poor, jerky or mistimed technique will result in the oscillation of the pendulum being interrupted. The images provided in
The pendulum may be positioned elsewhere and not necessarily on the frame.
The pendulum may comprise an elongate member. The elongate member may be rigid, or it may be flexible. The elongate member may have a mass at a location, for example its end, remote from where it is affixed to the frame of the device.
The construction of the frame of the device is shown in
Further detail regarding the resistance member attachment point is shown in
In use, a user may grip either upright section 615 of each handle 614, or the transverse section 616 of each handle to vary their grip on the device 500. In the embodiment of

Another example of an exercise device 600 is shown in
The device 600 comprises a discontinuous radially outwardly facing channel. Each of the second frame sections 118 comprises part of the channel. Each part of the radially outwardly facing channel is configured to receive a portion of a resistance member 142. In use, a first end of the resistance member 142 is attached to the device 600 and a second end of the resistance member 142 is attached to an external resistance point, as described above with reference to other embodiments. When the resistance member 142 is received in the channel in use, the resistance member 142 forms an arc which is tangential to one or more of the second frame sections 118;
In the embodiment of
The device 600 further comprises a substantially U-shaped handle 714. The handle 714 comprises a semi-circular body extending from a first end to a second end. The first and second ends are mounted to the first frame section 116. The handle 714 provides various grip positions and different points along the length of the body of the handle 714.
Another example of an exercise device 700 is shown in
The device 700 of
Another example of an exercise device 800 is shown in
The device 800 further comprises an upper rail 815 and a lower rail 816. The rails may form upper and lower lips of a discontinuous (or reduced depth) channel in which in use a cable, resilient rope or band or other or other resistance member is retained or held as the user twists their torso. The rails may provide a castellated series of projections and lands between the projections. The castellations of the upper and lower rail form radially outwardly flaring grooves or valleys in which the resistance member is received.
The resistance member may be a bungee cable or the like, for example an elastic resistance band that exerts progressively more resistance as it is stretched, or an inelastic cable such as a metal cable or the like.
The upper rail 815 is coupled to the second frame member 118 at the apex of the adjacent first portions 8171 of adjacent sections 817 of the upper rail 815 by a joint 819, such that the upper rail 815 protrudes from the second frame member 118 in a direction parallel to the plane of the second frame member 118. The lower rail 826 is coupled to the second frame member 118 in the same manner. The joints 819 may be any suitable joint, such as a weld joint. The joints 819 of the upper and lower rails 815, 816 are aligned with the same point along the circumference of the second frame member 118. The joints 819 of the upper and lower rails 815, 816 are spaced apart from each other in a direction perpendicular to the plane of the second frame member 118 to form a discontinuous (or periodically reduced depth) channel 830 extending about the circumference of the second frame member 118. The channel 830 is configured to receive a resistance member.
The rails of the embodiments shown may be continuous pieces of material (eg metal rod) attached to the frame of the device at spaced apart regions.
The rails may be welded to the outside surface of the frame, as shown in
The radially outwardly facing wall of the frame that part-defines the channel and that in use contacts and receives the resistance member may have a concave curvature so as to assist in positioning /holding the resistance member. That concave curve may be formed naturally by the act of bending rectangular hollow section tube to form the curved frame. The flat metal wall on the outside of a bent hollow rectangular cross section metal (e.g. steel) tube may naturally have an outwardly facing concave curve or camber on the outer “flat” face.
The arrangement of
The castellated/ intermittent/interrupted projections nature of the upper and lower rails, with projecting sections that are spaced from the frame member, and “gap” sections that are close to the frame member allows for gaps (viewed from above) between projection portions of the rails, and the resistance member can naturally use the gaps to feed into the groove defined by the upper and lower rails. By sliding to one end or the other, in use, of a castellated pair of upper and lower rail sections the resistance member is automatically placed adjacent the gaps in use at the point where it is connected to the selected rails. This makes threading the resistance member into the channel defined by the upper and lower rails easy for a user.
It will be appreciated that in other embodiments, the resistance member 142 may be attached to a different section of the upper rail 815, or to a section of the lower rail 816. A user may attach the resistance member 142 to any section of the upper or lower rails 815, 816 as appropriate.
In another variant the resistance member may be attached directly to one of the rails.
A second end of each resistance member 142, opposite the respective first end, is attached to an external resistance point 144. In this example, each external resistance point 144 comprises a bracket mounted to a wall by suitable means, such as one or more bolts. The user is facing away from the wall, with the device 800 in front them, and is gripping the handles of the device. The user can then rotate in either a clockwise or anticlockwise direction from the position shown to train the core muscles. In the example of
The various features and characteristics of the examples and embodiments described within this specification are interchangeable between the various examples and embodiments. Any attachment means, adjustment means, methods of using the device, to name just a few examples, are not limited to the example with which they are associated in the description but may be added or substituted in to any of the other examples and embodiments of the exercise device.
