VERTICAL ABDOMINAL CORE STABILIZATION EXERCISER

TECHNICAL FIELD

The present disclosure relates generally to exercise equipment and more particularly to an exercise device and system to aid in abdominal core muscle training.

BACKGROUND

The plank exercise is a popular exercise that is intended to work the core musculature (e.g. upper and/or lower body muscle(s), abdominal muscle(s), back muscle(s), hip muscle(s), gluteal muscle(s), etc.) of the body. Strengthening the core musculature not only provides additional support to the spine, thereby aiding ideal posture, but improves the performance of other exercises. The plank exercise is generally defined as a static exercise where an individual uses his or her arms to raise the individual's body off of the floor and holds the body straight and firm in a generally horizontal position relative to the floor, engaging the core musculature to do so.

Typically, the plank exercise is performed without any equipment, and is commonly performed on the ground where the hands and/or a portion of the arms (such as the forearms, elbows, etc.) are placed on the ground with the body in a prone position. The shoulders are typically positioned in line with the elbows, and the rest of the body is stiffened by contracting the core musculature such that they body forms a substantially straight horizontal line from the shoulders all the way down to the feet, which are supporting the other end of the body by resting on the ground (e.g., the toes are on the ground, the feet are on the ground, the individual is supported by the balls of his or her feet, with feet hip-distance apart, with feet together, the heels are on the ground when performing a reverse planking exercise, etc.).

SUMMARY

The inventors have found that facilitating a similar plank type exercise in a generally vertical condition improves, inter alia, greater muscle activation and blood lactate and force production. Accordingly, a device and system for facilitating a vertical plank exercise is described herein.

DETAILED DESCRIPTION

With reference to FIG. 1, an exercise device 1 is depicted. The exercise device 1 is configured to facilitate a user 2 in holding a vertical plank position on the exercise device 1. Specifically, the exercise device 1 includes a lower base 3 configured to support the exercise device 1 on a floor. The exercise device 1 also includes an upper support 4 disposed above the lower base 3. The upper support 4 is configured to suspend the user 2 on the exercise device 1 above the floor. For example, as depicted, the upper support 4 may be configured to support one or more arms of the user 2 such that the rest of the user's body hangs from the upper support 4 above the floor, with a force of gravity causing the user's body to be suspended generally vertically relative to the floor. The exercise device 1, however, also includes a plank positioner 5 disposed between the lower base 3 and the upper support 4 which is configured to support the user at an acute angle relative to the floor. For example, the plank positioner 5 may be configured to support one or more foot of the user, or one or more knee of the user, such that the user's body is aligned at an acute angle α1 relative to the floor, instead of being suspended exactly perpendicular to the floor. This position is referred to herein as the “vertical plank position”. The acute angle α1 may be in the range of, for example, 60 degrees to 89 degrees, 65 degrees to 88 degrees, 70 degrees to 87 degrees, or 75 degrees to 85 degrees. The exercise device 1 is therefore configured to cause the user to engage their core musculature in order to hold the vertical plank position on the exercise device 1.

With reference to FIGS. 2 and 23 a vertical core exercise device 10 for facilitating a user in performing a vertical plank exercise is depicted. The exercise device 10 includes a lower base 12, an upper platform 14, and an angularly disposed upward support frame 16 fixed to and extending between the lower base 12 and the upper platform 14. The lower base 12 provides a generally horizontal stabilization of the exercise device 10 at a lowermost end of the exercise device 10 and the upper platform 14 provides a generally horizontal stabilization of the exercise device 10 at an uppermost end of the exercise device 10. The support frame 16 is angularly affixed to and extending between the lower base 12 and the upper platform 14 in a stable manner.

The lower base 12 may be formed of a pair of lower parallel joists 18 spaced apart from each other by a width W1. The width W1, for example, may be in the range of 25.40 centimeters (10 inches) to 76.20 centimeters (30 inches), 30.48 centimeters (12 inches) to 68.58 centimeters (27 inches), or 38.10 centimeters (15 inches) to 60.96 centimeters (24 inches). The width W1 may be adjustable to other widths. The lower parallel joists 18 may have an overall length L1 of sufficient size to support the exercise device 10 and a user during a typical operation of the exercise device 10, which will be described in greater detail below. The length L1, for example, may be in the range of 50.80 centimeters (20 inches) to 177.80 centimeters (70 inches), 63.50 centimeters (25 inches) to 165.10 centimeters (65 inches), or 76.20 centimeters (30 inches) to 152.40 centimeters (60 inches). The length L1 may be adjustable to other lengths. The lower parallel joists 18 may be spaced apart and supported by a lower transverse joist 20 fixed to and extending between the lower parallel joists 18. A length of the lower transverse joist 20, therefore, may be equal to the width W1 of which the lower parallel joists 18 are spaced apart. The lower transverse joist 20 may be fixed to each of the lower parallel joists 18 by welding. However, it is understood that the lower transverse joist 20 may be fixed to each of the lower parallel joists 18 with any other suitable fixing means, such as screws or bolts. The lower transverse joist 20 may be fixed to each of the lower parallel joists 18 at any point along the length L1 of the lower parallel joists 18 and may extend between the lower parallel joists 18 at any angle. In the depicted embodiment, for example, the lower transverse joist 20 is fixed to each of the lower parallel joists 18 at or near an end thereof and extends between the lower parallel joists 18 generally perpendicular to each of the lower parallel joists 18. The lower parallel joists 18 and the lower transverse joist 20 are described herein as non-limiting examples, and it is understood that other supporting members other than joists may be used with the exercise device 10 described herein.

The lower base 12 may additionally include at least one handling bar 22 fixed to the lower base 12 and configured to assist a user in handling or moving the lower base 12 of the exercise device 10. As depicted, the at least one handling bar 22 includes two handling bars 22, each fixed to one of the lower parallel joists 18 at or near an end thereof and cantilevered from the respective ends of the lower parallel joists 18, extending parallel therewith. However, it is understood that the at least one handling bar 22 may include one handling bar 22 or more than two handling bars 22 and may be fixed to any other part of the lower base 12, such as for example another position on the lower parallel joists 18 or on the lower transverse joist 20. The at least one handling bar 22 may also be configured to be used as grasping points for a user to perform various other exercises, such as push-ups or exercises using resistance bands, on the exercise device 10.

The lower base 12, including the lower parallel joists 18, the lower transverse joist 20, and the at least one handling bar 22 may be formed of tubular or angular steel or aluminum members. However, it is understood that such materials and constructions should be considered merely exemplary and may be alternately substituted within a broad range of functional equivalents. The at least one handling bar 22 may include a cover or coating on at least a part of the at least one handling bar 22 configured to make handling or moving the lower base 12 more comfortable for a user when engaging the at least one handling bar 22. The cover or coating may be made of, for example, rubber, foam, fabric, leather, or any other suitable material configured to promote comfortable handling of the at least one handling bar 22.

The upper platform 14 may be formed by a pair of upper parallel joists 24 spaced apart by the same width W1 that the lower parallel joists 18 are spaced apart. The upper parallel joists 24 may also have the same overall length L1 as the lower parallel joists 18, but may be offset from the lower parallel joists 18 such that the upper parallel joists 24 are not disposed directly above and aligned with the lower parallel joists 18. It is understood, however, that the upper parallel joists 24 may alternatively have different dimensions than the lower parallel joists 18 that are still sufficient to support a user during a typical operation of the exercise device 10, which will be described in greater detail below.

The upper parallel joists 24 may be spaced apart and supported by an upper transverse joist 26 fixed to and extending between the upper parallel joists 24. A length of the upper transverse joist 26, therefore, may be equal to the width W1 of which the upper parallel joists 24 are spaced apart. The upper transverse joist 26 may be fixed to each of the lower parallel joists 24 by welding. However, it is understood that the upper transverse joist 26 may be fixed to each of the upper parallel joists 24 with any other suitable fixing means, such as screws or bolts. The upper transverse joist 26 may be fixed to each of the upper parallel joists 24 at or near an end thereof and may extend between the upper parallel joists 24 at any angle. In the depicted embodiment, for example, the upper transverse joist 26 extends between the upper parallel joists 24 generally perpendicular to each of the upper parallel joists 24. The upper parallel joists 24 and the upper transverse joist 26 are described herein as non-limiting examples, and it is understood that other supporting members other than joists may be used with the exercise device 10 described herein.

The upper platform 14 may include at least one mounting bar 28 and at least one stabilizing bar 30, each fixed to the upper platform 14 and configured to assist the user in mounting the exercise device 10 and stabilizing themselves on the exercise device 10, respectively. As depicted, the at least one mounting bar 28 includes two mounting bars 28, each fixed to one of the upper parallel joists 24 at a first end thereof and extending out from the end of each of the upper parallel joists 24. For example, the at least one mounting bar 28 may extend out from the first end of each of the upper parallel joists 24 such that they are cantilevered from the upper parallel joists 24 in a direction parallel to each of the upper parallel joists 24. In this way, a user can grasp the at least one mounting bar 28 to hoist themselves up onto the exercise device 10. Once hoisted up, the user may grasp the at least one stabilizing bar 30 to position themselves appropriately on the exercise device 10 and stabilize themselves thereon. The at least one mounting bar 28 may additionally be configured to be used as grasping points for a user to perform various other exercises, such as tricep dips, on the exercise device 10.

As depicted, the at least one stabilizing bar 30 includes two stabilizing bars 30, each fixed to one of the upper parallel joists 24 at or near a second end thereof and extending out from each of the upper parallel joists 24. For example, the at least one stabilizing bar 30 may extend out from each of the upper parallel joists 24 at an angle that is not parallel to each of the upper parallel joists 24. As depicted, the at least one stabilizing bar may extend out from each of the upper parallel joists 24 generally perpendicular to each of the upper parallel joists 24. In this way, the user can grasp the at least one stabilizing bar 30 to comfortably stabilize themselves on the exercise device 10 once mounted. The at least one stabilizing bar 30 may be repositionable on each of the upper parallel joists 24 so as to enable appropriate and comfortable grasping by a variety of users when they are mounted on the exercise device 10. Additionally, the at least one stabilizing bar 30 may be repositionable on another one of the upper parallel joists 24 so that more than one stabilizing bar 30 may be fixed to the same upper parallel joist 24. It is understood that the above-described positioning and orientation of the at least one mounting bar 28 and the at least one stabilizing bar 30 are described as non-limiting examples, and that other suitable arrangements may be suitable for the exercise device 10.

The upper platform 14 may additionally include a plurality of arm pads 32. For example, at least one of the plurality of arm pads 32 may be fixed to a respective one of the upper parallel joists 24 between the first and second end thereof. Another one of the plurality of arm pads 32 may be fixed to the upper transverse joist 26. The plurality of arm pads 32 may be removably fixed to the respective upper parallel joists 24 and the upper transverse joist 26, respectively, such that they are repositionable thereon. For example, the plurality of arm pads 32 may be removably fixed to the respective upper parallel joists 24 and the upper transverse joist 26 with a hook and loop fastener, snaps, buttons, screws, bolts, or any other suitable removable fixing means. As depicted, the arm pads 32 that are fixed to the upper parallel joists 24 may be disposed between a respective mounting bar 28 and stabilizing bar 30 of each of the parallel joists 24. In this way, once a user has mounted the exercise device 10 and is stabilized in the appropriate position by grasping the at least one stabilizing bar 30, the user's arms may rest comfortably on the plurality of arm pads 32 for supporting the user's weight on the exercise device 10. The arm pad 32 that is fixed to the upper transverse joist 26 is positioned so that when a user mounts the exercise device 10 and turns 90 degrees to the side, the user's arm may rest comfortably on the arm pad 32 on the upper transverse joist 26, facilitating the user in performing a side plank position. The plurality of arm pads 32 may be made of foam, fabric, leather, or any other suitable material configured to provide padding.

The upper platform 14, including the upper parallel joists 24, the upper transverse joist 26, the at least one mounting bar 28, and the at least one stabilizing bar 30 may be formed of tubular or angular steel members. However, it is understood that such materials and constructions should be considered merely exemplary and may be alternately substituted within a broad range of functional equivalents. The at least one mounting bar 28 and the at least one stabilizing bar 30 may additionally include a cover or coating on at least a part of the at least one mounting bar 28 and the at least one stabilizing bar 30, respectively, similar to the cover or coating on the at least one handling bar 22 previously described. The cover or coating, therefore, may be made of, for example, rubber, foam, fabric, leather, or any other suitable material configured to promote comfortable handling of the at least one mounting bar 28 and the at least one stabilizing bar 30.

The support frame 16, angularly extending between the lower base 12 and the upper platform 14, may be formed by a pair of parallel connecting struts 34, spaced apart from each other by the width W1. Each of the connecting struts 34 are fixed to respective lower parallel joists 18 of the lower base 12 at a lower end thereof and are fixed to respective upper parallel joists 24 of the upper platform 14 at an upper end thereof. The connecting struts 34 may have an overall length H1 of a sufficient size to support a user during a typical operation of the exercise device 10, as will be described in more detail below. For example, the length H1 of the connecting struts 34 may be in the range of 76.20 centimeters (30 inches) to 177.80 centimeters (70 inches), 88.90 centimeters (35 inches) to 165.10 centimeters (65 inches), or 101.60 centimeters (40 inches) to 152.40 centimeters (60 inches).

The connecting struts 34 may be spaced apart and supported by at least one supporting transverse joist 36 fixed to and extending between the connecting struts 34. A length of the at least one supporting transverse joist 36, therefore, may be equal to the width W1 of which the connecting struts 34 are spaced apart. The at least one supporting transverse joist 36 may be fixed to each of the connecting struts 34 by welding. However, it is understood that the at least one supporting transverse joist 36 may be fixed to each of the connecting struts 34 with any other suitable fixing means, such as screws or bolts. The at least one supporting transverse joist 36 may be fixed to each of the connecting struts 34 at any position along the length H1 of the connecting struts 34 and may extend between the upper parallel joists 24 at any angle. In the depicted embodiment, for example, the at least one supporting transverse joist 36 includes two supporting transverse joists 36 each disposed at or near a respective upper and lower end of the connecting struts and extending between the connecting struts 34 generally perpendicular to each of the connecting struts 34. The supporting transverse joist 36 is described herein as a non-limiting example, and it is understood that another supporting member other than a joist may be used with the exercise device 10 described herein. Alternatively, the exercise device 10 may not include a supporting transverse joist 36 whatsoever.

The upper and lower ends of each of the connecting struts 34 may be fixed to the respective lower parallel joists 18 and upper parallel joists 24 by welding. However, it is understood that the upper and lower ends of each of the connecting struts 34 may be fixed to the respective lower parallel joists 18 with any other suitable fixing means, such as screws or bolts. The upper and lower ends of each of the connecting struts 34 may therefore include respective mounting flanges 38 through which the screws or bolts may pass to fix the connecting struts 34 to the respectively lower parallel joists 18 and the upper parallel joists 24. It is understood, however, that upper and lower ends of each of the connecting struts 34 may be fixed to the respective lower parallel joists 18 and the upper parallel joists 24 with any other suitable fixing means, such as for example, welding.

The connecting struts 34 extend from the lower parallel joists 18 at an angle α1 that is of a sufficient arc to allow a user to position themselves in an upright and straight planking position when mounted on the exercise device 10, as will be described in more detail below. The angle α1 may therefore be an acute angle. Specifically, the angle α1 may be between approximately 60 degrees to 89 degrees, 65 degrees to 88 degrees, 70 degrees to 87 degrees, or 75 degrees to 85 degrees. The connecting struts 34 similarly extend from the upper parallel joists 18 at the angle α1, as depicted.

The support frame 16 includes a plank positioning plate 40 fixed to and extending between the connecting struts 34 of the support frame 16. The plank positioning plate 40 may additionally be fixed to at least one of the at least one supporting transverse joists 36 for additional support of the plank positioning plate 40. For example, as depicted, the plank positioning plate 40 is fixed to the connecting struts 34 on respective side edges of the plank positioning plate 40 and is fixed to a lower one of two supporting transverse joists 36 on the support frame 16. The plank positioning plate 40 may have a relatively flat polygonal shape. For example, the plank positioning plate 40 may have a quadrilateral shape, such as a square or a rectangle. In this manner, the plank positioning plate 40 can securely affix to each of the connecting struts 34 along the entirety of the respective side edges of the plank positioning plate 40 and can securely affix to the at least one supporting transverse joist 36 along the entirety of a respective top edge of the plank positioning plate 40.

The support frame 16, including the connecting struts 34, the at least one supporting transverse joist 26 may be formed of tubular or angular steel members. The plank positioning plate 40 of the support frame 16 may be formed of a plate-like steel or aluminum member. It will be understood, however, that such materials and constructions should be considered merely exemplary and may be alternately substituted within a broad range of functional equivalents.

The exercise device 10 described herein is configured to assist a user in maintaining an appropriate vertical plank position when operating the exercise device 10. Specifically, in operation, the user mounts themselves on the exercise device 10 with assistance from the at least mounting bar 28, as previously described. The user then positions their body with the assistance of the at least one stabilizing bar 30 such that their forearms are positioned approximately at a 90 degree angle relative to their upper arms and are resting on the plurality of arm pads 32, while the user grasps the at least one stabilizing bar 30 with their hands. In this position, the user's feet naturally fall against the plank positioning plate 40 with the force of gravity. As the user's feet engage the plank positioning plate 40, the user is able to position their body along a generally straight line from the crown of their head to their heels, angled relative to the floor between approximately 85 degrees to approximately 75 degrees (referred to herein as a vertical plank position). The user can hold the vertical plank position for any duration of time, such as 30 seconds, or may choose to hold the vertical plank position for as long as possible, engaging their core musculature to do so. Unlike a free-style plank performed without any equipment, the use of the exercise device 10 described herein allows the user to maintain the vertical plank position without putting undesirable stress on the user's lower back.

Now turning to FIGS. 4-6, an exercise system 50 for facilitating a user in performing a vertical plank exercise is depicted. The exercise system 50 includes a discrete upper platform 52 and a discrete lower plank positioning platform 54, both of which are configured to be removably mounted onto a support frame 56, as depicted in FIG. 6. Specifically, the upper platform 52 and the lower plank positioning platform 54 are configured to be removably mounted onto the support frame 56 such that the upper platform 52 is positioned above the lower plank positioning platform 54, spaced apart from the lower plank positioning platform 54 a suitable distance so that the user's forearms can engage the upper platform 52 while the user's feet can engage the lower plank positioning platform 54 when the user is in the vertical plank position. The support frame 56 may be part of another exercise machine, for example a vertical frame member of a support frame of the other exercise machine. Alternatively, the support frame 56 may be a discrete stand-alone support frame 56. The support frame 56 may be formed of tubular or angular steel members. However, it is understood that such materials and constructions should be considered merely exemplary and may be alternately substituted within a broad range of functional equivalents.

Referring to FIG. 4 in particular, the upper platform 52 will be described in detail first. The upper platform 52 may be formed by a pair of upper parallel joists 58 adjustably spaced apart by a variable width W2. The variable width W2 may be, for example, in the range of 25.40 centimeters (10 inches) to 76.20 centimeters (30 inches), 30.48 centimeters (12 inches) to 68.58 centimeters (27 inches), or 38.10 centimeters (15 inches) to 60.96 centimeters (24 inches). The upper parallel joists 58 may be adjustably spaced apart with and supported by an upper transverse joist 60 adjustably fixed to and extending between the upper parallel joists 58. The upper parallel joists 58, for example, may each have a perpendicularly extending protrusion 59 configured to adjustably mate with the upper transverse joist 60 such that the perpendicularly extending protrusions 59 can slide in and out of the upper transverse joist 60. In this manner, a desired width W2 may be established and the perpendicularly extending protrusions 59 of the upper parallel joists 58 may be fixed to the upper transverse joist 60 accordingly. The perpendicularly extending protrusions 59 of the upper parallel joists 58 may be fixed to the upper transverse joist 60 with, for example, screws or bolts. The upper parallel joists 58 may have an overall length L2 to support a user's forearms during a typical operation of the exercise system 50, which will be described in greater detail below. The length L2 may be, for example, in the range of 25.40 centimeters (10 inches) to 101.60 centimeters (40 inches), 38.10 centimeters (15 inches) to 88.90 centimeters (35 inches), or 50.8 centimeters (20 inches) to 76.20 centimeters (30 inches). The upper parallel joists 58 and the upper transverse joist 60 are described herein as non-limiting examples, and it is understood that other supporting members other than joists may be used with the exercise device 10 described herein.

The upper platform 52 includes an upper mounting bracket 51 and an upper mounting bracket arm 53 configured to removably mount the upper platform 52 to the support frame 56. The upper mounting bracket arm 53 is fixed to and extends between the upper mounting bracket 51 and the upper transverse joist 60. The upper mounting bracket arm 53 may be fixed to the upper mounting bracket 51 and the upper transverse joist 60 by welding. However, it is understood that the upper mounting bracket arm 53 may be fixed to the upper mounting bracket 51 and the upper transverse joist 60 with any other suitable fixing means, such as screws or bolts. The upper mounting bracket 51 may be a U-shaped bracket configured to fit around and be removably fixed to the support frame 56. For example, the upper mounting bracket 51 may be removably fixed to the support frame 56 with screws or bolts.

The upper platform 52 may additionally include at least one mounting bar 62 and at least one stabilizing bar 64, each fixed to the upper platform 52 and configured to assist the user in mounting the exercise system 50 and stabilizing themselves on the exercise system 50, respectively. As depicted, the at least one mounting bar 62 includes two mounting bars 62, each fixed to one of the upper parallel joists 58 at a first end thereof and extending out from the end of each of the upper parallel joists 58. For example, the at least one mounting bar 62 may extend out from the first end of each of the upper parallel joists 58 such that they are cantilevered from the upper parallel joists 58 in a direction parallel to each of the upper parallel joists 58. In this way, a user can grasp the at least one mounting bar 62 to hoist themselves up onto the upper platform 52 of the exercise system 50 once the upper platform 52 has been mounted to the support frame 56 at an appropriate height. Once hoisted up, the user may grasp the at least one stabilizing bar 64 to position themselves appropriately on the exercise system 50 and stabilize themselves thereon. The at least one mounting bar 62 may additionally be configured to be used as grasping points for a user to perform various other exercises, such as tricep dips, on the exercise system 50.

As depicted, the at least one stabilizing bar 64 includes two stabilizing bars 64, each fixed to one of the upper parallel joists 58 at or near a second end thereof and extending out from each of the upper parallel joists 58. For example, the at least one stabilizing bar 64 may extend out from each of the upper parallel joists 58 at an angle that is not parallel to each of the upper parallel joists 58. As depicted, the at least one stabilizing bar 64 may extend out from each of the upper parallel joists 58 generally perpendicular to each of the upper parallel joists 58. In this way, the user can grasp the at least one stabilizing bar 64 to comfortably stabilize themselves on the exercise system 50 once mounted. The at least one stabilizing bar 64 may be repositionable on each of the upper parallel joists 58 so as to enable appropriate and comfortable grasping by a variety of users when they are mounted on the exercise system 50. Additionally, the at least one stabilizing bar 64 may be repositionable on another one of the upper parallel joists 58 so that more than one stabilizing bar 64 may be fixed to the same upper parallel joist 58. It is understood that the above-described positioning and orientation of the at least one mounting bar 62 and the at least one stabilizing bar 64 are described as non-limiting examples, and that other suitable arrangements may be suitable for the exercise system 50.

The upper platform 52 may additionally include a plurality of arm pads 55, each fixed to a respective one of the upper parallel joists 58 between the first and second end thereof. The plurality of arm pads 55 are similar to the arm pads 32 of the exercise device 10, described above with reference to FIGS. 2 and 3. For example, at least one of the plurality of arm pads 55 may be removably fixed to a respective one of the upper parallel joists 58 between the first and second end thereof such that they are repositionable thereon. Another one of the plurality of arm pads 55 may be fixed to the upper transverse joist 60. The plurality of arm pads 55 may be removably fixed to the respective upper parallel joists 58 and the upper transverse joist 60 with a hook and loop fastener, snaps, buttons, screws, bolts, or any other suitable removable fixing means. The arm pads 55 that are fixed to the upper parallel joists 58 may be disposed between a respective mounting bar 62 and stabilizing bar 64 of each of the upper parallel joists 58. In this way, once a user has mounted the exercise system 50 and is stabilized in the appropriate position by grasping the at least one stabilizing bar 64, the user's arms may rest comfortably on the plurality of arm pads 55 for supporting the user's weight on the exercise system 50. The arm pad 55 that is fixed to the upper transverse joist 60 is positioned so that when a user mounts the exercise system 50 and turns 90 degrees to the side, the user's arm may rest comfortably on the arm pad 55 on the upper transverse joist 60, facilitating the user in performing a side plank position. The plurality of arm pads 55 may be made of foam, fabric, leather, or any other suitable material configured to provide padding.

The upper platform 52, including the upper parallel joists 58, the upper transverse joist 60, the at least one mounting bar 62, and the at least one stabilizing bar 64 may be formed of tubular or angular steel members. However, it is understood that such materials and constructions should be considered merely exemplary and may be alternately substituted within a broad range of functional equivalents. The at least one mounting bar 62 and the at least one stabilizing bar 64 may additionally include a cover or coating on at least a part of the at least one mounting bar 62 and the at least one stabilizing bar 64, respectively. The cover or coating may be made of, for example, rubber, foam, fabric, leather, or any other suitable material configured to promote comfortable handling of the at least one mounting bar 62 and the at least one stabilizing bar 64.

Referring to FIG. 5, in particular, the lower plank positioning platform 54 will now be described in detail. The lower plank positioning platform 54 includes an adjustable plank positioning plate 66, a lower mounting bracket 68, and a lower mounting bracket arm 70. The lower mounting bracket 68 and the lower mounting bracket arm 70 are configured to removably and adjustably mount the lower plank positioning platform 54 to the support frame 56 below the mounted upper platform 52. Specifically, the lower plank positioning platform 54 is configured to be removably mounted to the support frame 56 such that it is spaced below the upper platform 52 at least a distance sufficient to allow the user's feet to engage the lower plank positioning platform 54 while the user's forearms engage the upper platform 52 when the user is in the vertical plank position. The lower mounting bracket arm 70 is fixed to and extends between the lower mounting bracket 68 and a back face of the plank positioning plate 66. The lower mounting bracket arm 70 may be fixed to the lower mounting bracket 68 and the back face of the plank positioning plate 66 by welding. However, it is understood that the lower mounting bracket 70 may be fixed to the lower mounting bracket 68 and the back face of the plank positioning plate 66 with any other suitable fixing means, such as screws or bolts. The lower mounting bracket 68 may be a U-shaped bracket similar to the upper mounting bracket 51, configured to fit around and be removably fixed to the support frame 56. For example, the lower mounting bracket 68 may be removably fixed to the support frame 56 with screws or bolts.

The lower mounting bracket arm 70 may be adjustable so as to adjust the spacing between the lower mounting bracket 68 and the back face of the plank positioning plate 66. For example, the lower mounting bracket arm 70 may be extended to space the plank positioning plate 66 further from the lower mounting bracket 68. The further that the plank positioning plate 66 is spaced from the lower mounting bracket 68, the more difficult the exercise will be for the user.

The plank positioning plate 66 may include at least one handling bar 72 fixed to a front face of the plank positioning plate 66 and configured to assist a user in handling or moving the lower plank positioning platform 54. As depicted, the at least one handling bar 72 includes two handling bars 72, each fixed to the front face of the plank positioning plate 66 at or near side edges thereof. However, it is understood that the at least one handling bar 72 may include one handling bar 72 or more than two handling bars 72 and may be fixed to any other part of the lower plank positioning platform 54. The at least one handling bar 72 may also be configured to be used as grasping points for a user to perform various other exercises with the exercise system 50.

The plank positioning plate 66 may have a relatively flat polygonal shape. For example, the plank positioning plate 66 may have a quadrilateral shape, such as a square or a rectangle. The plank positioning plate 66 is configured to extend at an angle α2, relative to the support frame 56, that is of a sufficient arc to allow a user to position themselves in an upright and straight planking position when mounted on the exercise system 50, as will be described in more detail below. The angle α2 may therefore be an acute angle. Specifically, the angle α2 may be between approximately 60 degrees to 89 degrees, 65 degrees to 88 degrees, 70 degrees to 87 degrees, or 75 degrees to 85 degrees.

The plank positioning plate 66 may include a flange 74 on a bottom edge thereof and the lower plank positioning platform 54 may additionally include a foot pad 76 positioned on a bottom face of the flange 74. The foot pad 76 is configured, for example, to provide cushioning for the user's heels while performing a Nordic curl exercise. Specifically, a user may use the lower plank positioning platform 54 to support the user's feet between the Nordic curl pad 76 and the floor as the user performs the Nordic curl exercise. The foot pad 76 may alternatively be used to assist the user in performing a variety of other exercises. The foot pad 76 may be removably fixed to the bottom face of the flange 74 or may be permanently fixed thereto.

The lower plank positioning platform 54, including the lower mounting bracket 68, the lower mounting bracket arm 70, and the at least one handling bar 72 may be formed of tubular or angular steel members. The plank positioning plate 66 of the lower plank positioning platform 54 may be formed of a plate-like steel or aluminum member. The foot pad 76 may be made of foam, fabric, leather, or any other suitable material configured to provide padding. It will be understood, however, that such materials and constructions should be considered merely exemplary and may be alternately substituted within a broad range of functional equivalents. The at least one handling bar 72 may include a cover or coating on at least a part of the at least one handling bar 72. The cover or coating may be made of, for example, rubber, foam, fabric, leather, or any other suitable material configured to promote comfortable handling of the at least one handling bar 72.

The exercise system 50 described herein is configured to assist a user in maintaining an appropriate vertical plank position when operating the exercise system 50. Specifically, in operation, the user mounts themselves on the exercise system 50 with assistance from the at least mounting bar 62 of the upper platform 52. The user then positions their body with the assistance of the at least one stabilizing bar 64 of the upper platform 52 such that their forearms are positioned approximately at a 90 degree angle relative to their upper arms and are resting on the plurality of arm pads, while the user grasps the at least one stabilizing bar 64 with their hands. In this position, the user's feet naturally fall against the plank positioning plate 66 of the lower plank positioning platform 54 with the force of gravity. As the user's feet engage the plank positioning plate 66, the user is able to position their body along a generally straight line from the crown of their head to their heels, angled relative to the floor between approximately 85 degrees to approximately 75 degrees (referred to herein as the vertical plank position). The user can hold the vertical plank position for any duration of time, such as 30 seconds, or may choose to hold the vertical plank position for as long as possible, engaging their core musculature to do so. Unlike a free-style plank performed without any equipment, the use of the exercise system 50 described herein allows the user to maintain the vertical plank position without putting undesirable stress on the user's lower back.

With reference to FIG. 7, a method 100 of performing a vertical plank exercise on an exercise device is depicted. The exercise device may be the same as the exercise device 1, 10 or the exercise system 50 described herein. The method includes a step 102 of mounting the exercise device so as to suspend a user's body above a floor. The step 102 of mounting the exercise device, for example, may include supporting at least one arm of the user on an upper support of the exercise device. For example, the user may mount themselves on the exercise device with assistance from at least mounting bar (such as the at least one mounting bar 28 or 62 described herein) of the upper support.

The method 100 then includes a step 104 of positioning the user's body at an acute angle relative to the floor with the use of a plank positioner. The step 104 of positioning the user's body may include positioning the user's body with the assistance of at least one stabilizing bar (such as the at least one stabilizing bar 30 or 64 described herein) such that their forearms are positioned approximately at a 90 degree angle relative to their upper arms and are resting on a plurality of arm pads (such as the plurality of arm pads 32 or 55 described herein), while the user grasps the at least one stabilizing bar with their hands. In this position, the user's legs will naturally fall against the plank positioner with the force of gravity. The step 104 of positioning the user's body therefore may also include supporting at least one leg of the user with the plank positioner. The plank positioner may be the same as the plank positioning plate 40 or 66 described herein. As the user's legs are supported by the plank positioner, the user's body is positioned along a generally straight line from the crown of their head to their heels, angled relative to the floor at the acute angle. The acute angle may be between approximately 60 degrees to 89 degrees, 65 degrees to 88 degrees, 70 degrees to 87 degrees, or 75 degrees to 85 degrees. The user can hold this vertical plank position for any duration of time, such as 30 seconds, or may choose to hold the vertical plank position for as long as possible, engaging their core musculature to do so. Unlike performing a free-style plank without any equipment, performing the method 100 described herein allows the user to maintain the vertical plank position without putting undesirable stress on the user's lower back. The user performing the method 100 is also depicted in FIG. 1.
