The present invention relates generally to a strength training apparatus. More particularly, the present invention relates to a strength training apparatus for performing a hip thrust exercise for training the gluteus (“glute”) muscles.
A common exercise routine used by athletes to train and specifically target their glute muscles is known as the “glute bridge” exercise. During the typical glute bridge exercise, the athlete places her back and at least one of her feet on a supporting surface to support her weight. Her back and foot remain in contact with these support surfaces throughout the entire exercise. In the concentric phase of the exercise, the athlete pushes her hips forward while contracting her glute muscles (the “up” or “hip extended” position). In this up position, the athlete's upper body and upper leg (i.e., femur) are aligned and form a substantially straight line or an angle of approximately 180° is formed at the athlete's hips and extends from the athlete's shoulders to her knees. In the eccentric phase of the exercise, the athlete flexes her hips rearwards and relaxes her glute muscles (the “down” or “hip flexed” position). In this down position, the athlete's upper body and upper leg are approximately orthogonal to one another such that an approximate angle of 90° is formed at the athlete's hips by her torso and femur.
In its simplest form, the glute bridge may be performed on the floor or other ground surface without any equipment. In that case, the athlete's shoulders and feet are supported by the ground surface. One disadvantage to performing the glute bridge exercise with back and feet supported by surfaces on the same plane (i.e., both supported by the ground) is that it provides limited range of motion, which limits the effectiveness of the exercise. One way to improve the effectiveness of the exercise routine through increasing the range of motion is for the athlete to place her back on a support surface that is on a different plane (typically a higher plane) from the surface supporting her feet, as shown in
The difficulty of the glute bridge exercise may be increased by applying resistance to the movement of the athlete's hips. Often, this is accomplished by placing a barbell across the athlete's hips, which the athlete must then raise during the concentric phase of the exercise, as shown in
Accordingly, what is needed is a method and apparatus that offers the advantages of performing an elevated glute bridge exercise (hip thrust) that addresses the disadvantages discussed above.
The use of the terms “a”, “an”, “the” and similar terms in the context of describing embodiments of the invention are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. The terms “comprising”, “having”, “including” and “containing” are to be construed as open-ended terms (i.e., meaning “including, but not limited to,”) unless otherwise noted. The terms “substantially”, “generally” and other words of degree are relative modifiers intended to indicate permissible variation from the characteristic so modified. The use of such terms in describing a physical or functional characteristic of the invention is not intended to limit such characteristic to the absolute value which the term modifies, but rather to provide an approximation of the value of such physical or functional characteristic.
Terms concerning attachments, coupling and the like, such as “attached”, “connected” and “interconnected”, refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both moveable and rigid attachments or relationships, unless otherwise specified herein or clearly indicated as having a different relationship by context. The term “operatively connected” is such an attachment, coupling or connection that allows the pertinent structures to operate as intended by virtue of that relationship.
The use of any and all examples or exemplary language (e.g., “such as” and “preferably”) herein is intended merely to better illuminate the invention and the preferred embodiments thereof, and not to place a limitation on the scope of the invention. Nothing in the specification should be construed as indicating any element as essential to the practice of the invention unless so stated with specificity.
The term “femur angle” is relative to a linear approximation of the user's spine. The “hip region” is located generally on the front of the user's body and extends generally from the top of the hipbone downwards to approximately midpoint of the femur. The term “hip flexed position” means that the user's hips are generally flexed rearward and (i) the user has a femur angle of approximately 90°, (ii) the user's back is supported by a back support, and (iii) the user's foot of the leg whose femur is angled at approximately 90° is supported by a foot support. The term “hip extended position” means that the user's hips are generally extended forward and (i) the user has a femur angle of approximately 180°, (ii) the user's back is supported by a back support, and (iii) the user's foot of the leg whose femur is angled at approximately 180° is supported by a foot support.
The above and other needs are met by an apparatus for use in performing a weighted glute bridge exercise where a user alternates between a hip flexed position and a hip extended position. The apparatus includes a back support that contacts a user's back and supports a portion of the user's weight and a foot support that contacts at least one of the user's feet and also supports a portion of the user's weight when the user's back is supported by the back support. The back support and the foot support remain fixed in place throughout the exercise. However, in certain preferred embodiments, the foot support includes a first end and a hinged second end such that the first end of the foot support may be raised and lowered about the hinged second end and fixed in at least two positions.
A rigid elongate arm is pivotally mounted adjacent a left side or a right side of the back support at a pivot point. A hip bar is connected to the elongate arm at a hip bar connection and is configured to contact the user's hip region throughout the exercise. When the user moves from the hip flexed position to the hip extended position, the elongate arm moves from a first pivotal position to a second pivotal position (in a first direction). When the user moves from the hip extended position to the hip flexed position, the elongate arm moves from the second pivotal position back to the first pivotal position (in a second direction). A resistance loading area may be used to optionally apply a resistance force to the elongate arm that resists pivotal movement of the elongate arm in the first direction to increase the difficulty of the exercise. The resistance loading area is located on the elongate arm near the hip bar connection such that the resistance force is applied substantially directly onto the user's hip region in order to closely replicate conventional weight hip thrust exercises.
In certain preferred embodiments, rigid elongate arms are pivotally mounted adjacent both sides of the back support and the hip bar is connected between the elongate arms. Each of the elongate arms has a first portion located on one side of the pivot point and a second portion located on an opposite side of the pivot point that is closer to the foot support than the first portion of the elongate arm. The hip bar is preferably connected between the second portions of the elongate arms and may be selectively disconnected from at least one of the elongate arms. A rigid connection member connects the first portions of the elongate arms together such that the elongate arms pivot simultaneously with one another during the exercise.
According to certain embodiments, a hinged side of the hip bar is hinge mounted to one of the elongate arms such that the hip bar may swing between an open position and a closed position. When the hip bar is in the closed position, a locking side of the hip bar (located opposite the hinged side) may be removably connected to the other elongate arm via a lock. The lock moves between an unlocked position, where the hip bar may be pivoted about the hinge to the open position, and a locked position, where the hip bar is prevented from being pivoted about the hinge to the open position. The lock may include a first tube located on the elongate arm that is located proximate the locking side of the hip bar. In that case, a corresponding second tube is also located on the back support and it aligns with the first tube when the hip bar is in the closed position. A sliding bolt is configured to slide through the first and second tubes. When the lock is in the locked position, a portion of the sliding bolt is located in each of the first and second tubes. When the lock is in the unlocked position, the sliding bolt is located in only one of the first and second tubes.
In certain preferred embodiments, the resistance loading area is an elongate post extending laterally outwards from the elongate arm that is configured to receive weight plates. In certain embodiments, rigid elongate arms are pivotally mounted adjacent both sides of the back support and resistance loading areas are provided on each elongate arm. The resistance loading areas preferably allow a separate resistance force to be applied to each of the elongate arms. In preferred embodiments, each resistance loading area is an elongate post extending laterally outwards from the elongate arm that is configured to receive weight plates. The elongate arms have a first portion located on one side of the pivot point and a second portion located on an opposite side of the pivot point that is closer to the foot support than the first portion of the elongate arm. Preferably, the hip bar is connected between the second portions of the elongate arms and the elongate posts are concentrically aligned with the hip bar to closely replicate the appearance and performance characteristics of a conventional weight hip thrust exercises with a barbell.
Certain embodiments of the apparatus are provided with a pivot-limiting leg. A first end of the pivot-limiting leg is mounted to the elongate arm and a second end is configured to contact a bearing surface once the elongate arm has pivoted sufficiently far enough about the pivot point in the second direction. Through that contact, the pivot-limiting leg automatically prevents further pivoting of the elongate arm about the pivot point in the second direction.
Certain embodiments of the apparatus includes a catch that (i) when engaged, statically holds the elongate arm in a pivotal position that is between the first pivotal position and the second pivotal position and (ii) when disengaged, allows the elongate arm to freely pivot between the first pivotal position and the second pivotal position. Preferably, the catch includes an arm that is pivotally mounted at one end between the back support and the foot support and that pivots about the one end between an engaged position and a disengaged position. A cradle is formed near an end of the arm that is opposite the pivot point. The catch is engaged by pivoting the arm to the engaged position and placing the elongate arm into the cradle such that the elongate arm is statically held between the first pivotal position and the second pivotal position. The catch is disengaged by pivoting the elongate arm in the first direction to remove the elongate arm from the cradle and moving the arm to the disengaged position. In certain embodiments, rigid elongate arms are pivotally mounted adjacent both sides of the back support and a catch is located on each side of the back support to support an elongate arm, as described above. Preferably, a linkage connects the two catches together, such that engaging or disengaging one catch will also automatically engage or disengage the opposite catch, respectively.
Further advantages of the invention are apparent by reference to the detailed description when considered in conjunction with the figures, which are not to scale so as to more clearly show the details, wherein like reference numerals represent like elements throughout the several views, and wherein:

Referring now to
In the illustrated embodiment, the apparatus 100 includes a supporting frame or base 112 that is placed onto a ground surface. The base has a front 114, rear 116, left side 118, and right side 120. Risers 122 extend generally vertically upwards from the left and right sides 118, 120 at the rear 116 of the base 112. The back support 102 is mounted between the two risers 122 at approximately ⅔ the height of the risers. The back support 102 is configured to contact a user's back and to support a portion of the user's weight. In this embodiment, the back support is formed by a rod (128, shown in
The foot support 104 is a plate-like surface that preferably extends from just in front of the hip bar 108 to the front 114 of the base 112. Preferably, the foot support 104 includes a first end 104A and a hinged second end 104B that is closer to the back support 102 than the first end. Preferably, the first end 104A of the foot support 104 may be raised and lowered about the hinged second end 104B and fixed in at least two positions.
As shown best in
Preferably, a handle 138 is provided on the foot support 104 to facilitate raising and lowering the foot support. The slot 136 and hinge 130 are preferably configured such that pulling upwards on the handle 138 to lift the foot support 104 automatically causes the rod 134 to slide along the slot and, once the handle is released, to automatically be seated at the end of the slot nearest the first end 104A of the foot support 104, such that the foot support is held at an inclined angle. To lower the foot support 104, the first end 104A is first raised and then the rod 134 is pushed rearward along the slot 136 towards the second end 104B of the foot support. Since both rods 134 are connected to the same hinge 130, which acts as a linkage, moving a rod on one side of the apparatus 100 (e.g., the right side) also simultaneously moves the rod on the opposite side of the apparatus (e.g., the left side). This allows the angle of incline of the foot support 104 to be adjusted from either the left or right side of the apparatus 100.
The foot support 104 is configured to contact at least one of the user's feet and to support a portion of the user's weight when the user's back is supported by the back support 102. As discussed above, the foot support 104 is preferably a plate-like surface. However, in other embodiments, the foot support 104 could be a ground, floor, or other surface. To mimic the elevated hip thrust discussed above, the back support 102 and foot support 104 are preferably located on two different vertical planes (i.e., the back support is vertically higher than the foot support). More preferably, the top of the back support 102 is raised to a vertical height above the foot support 104 by a distance that replicates the height difference between the top of a standard weightlifting bench and the ground surface that it rests on (approximately 18″ to approximately 24″). In some embodiments, either of the back support 102 and foot support 104 may be moved, pivoted, rotated. An example of a pivoting foot support 104 is described below. However, the back support 102 and foot support 10 preferably remain fixed in place throughout the exercise in order to provide a stable support surface for the user.

As shown in
As discussed above, to perform the exercise, the user first assumes the hip flexed position with his hip region located below the hip bar 108. To accomplish this, the user may first step into the pivoting enclosure between the back support 102 and hip bar 108 and then seat himself on a middle support 142, which may be provided with a padded seat 144. Once seated, the user then positions his back against the back support 102 and his feet onto the foot support 104, raises his hip region to the hip 108, and begins the exercise.
However, more preferably, at least one side of the hip bar 108 may be selectively disconnected from at least one of the elongate arms 106 in order to provide more convenient access to the pivoting enclosure. For example, in some embodiments, both sides of the hip bar 108 may be disconnected from the elongate arms 106 via a removable hip bar connection 140. In other embodiments, only one side of the hip bar 108 is disconnected. For example, as illustrated in
More detailed views of the hinged hip bar connection and the locking hip bar connection are provided in
As discussed above, the difficulty of the glute bridge exercise may be increased by applying resistance to the movement of the athlete's hips. Traditionally, this is done by placing a weighted barbell across the athlete's hip region. Accordingly, in preferred embodiments, the apparatus 100 is provided with the resistance loading area 110, which may be used for applying a resistance force to the user's hip region. Referring again to
The resistance loading area 110 and the type of resistance applied may take many forms. For example, a resistance band could be connected between the elongate arm and the base 112 via hooks that are located on each structure. Alternatively, one end of a cable could be connected to the elongate arm 106 at the resistance loading area 110. The cable could then be routed to a weight stack using known methods to provide an easily adjustable resistance load. In the illustrated embodiment, the resistance loading area 110 is an elongate post that extends laterally outwards from the elongate arm 106 and that is configured to receive weight plates.
In order to more closely replicate the feel and performance of conventional weighted glute bridge exercises, the apparatus 100 preferably includes a pair of elongate posts 110 that extend laterally outwards in opposite directions from the elongate arms 106. These posts are preferably concentrically aligned with the hip bar 108 (i.e., they are collinear or placed along a straight line). The arrangement gives the appearance and performance characteristics (i.e., motion path) of having a traditional weighted barbell placed across the athlete's hip area.
The presently-disclosed apparatus 100 may be provided with a number of optional safety and convenience features that are not available when performing the glute bridge according to conventional methods. For example, as shown in
Additionally, in some preferred embodiments, the apparatus 100 may include a catch that contacts a portion of the pivoting enclosure and that holds the pivoting enclosure between the first pivotal position and the second pivotal position. The catch is used between exercise sets to hold the hip bar 108 (and leg 154) in a raised position away from the base 112 and the pivoting enclosure at a slightly pivoted position. Having the hip bar 108 spaced away from the base 112 facilitates the athlete's entry and exit of the apparatus 100. Having the pivoting enclosure at a slightly pivoted position makes beginning and ending the exercise more comfortable and controlled.
The catch may take any form that is capable of holding the pivoting enclosure in a partially pivoted position away. For example, a spring-loaded or detent pin could be configured to engage an opening formed in the elongate arm. In other cases, the catch could take the form of a brake mounted to the pivot points 124. However, in the illustrated embodiment, the catch is a bar that, when swung to a vertical position, contacts and vertically supports a lower portion of the pivoting enclosure. More particularly, the catch includes an elongate bar 158 having a bottom end that is pivotally mounted to a lower portion of the frame 112 to enable the bar to swing rearwards towards the back support 102 to an angled and disengaged position. When disengaged, the bar 158 is preferably supported by an angled rest 160 that is also mounted to a lower portion of the frame 112. The bar 158 also swings forward about its pivotal mounting point to a substantially vertical and engaged position. A cradle 162 is located on a forward face of the bar 158 (i.e., on the side nearest the foot support 104). When the bar 158 is engaged, the cradle 162 is positioned under and vertically supports a post 164 that extends laterally outwards from the side of the elongate arm 106 (or, in this particular case, the leg 154 mounted to the elongate arm 106), which supports the pivoting enclosure in a slightly pivoted location.
The bar 158 is mounted between the back support 102 and the foot support 104. Preferably, the bar 158 is sized and configured such that it may always be easily grasped by a user in either the engaged or disengaged position when that user's back is on the back support 102 and his feet are on the foot support 104. Therefore, as a safety and convenience feature, the bar 158 and post 164 are sized and positioned such that the bar cannot swing beyond the post 164. Therefore, in order to swing the bar 158 forward, it must be engaged and placed under the post 164. In this case, the bar 158 extends upwards past the post 164 and the post 164 extends outward from the leg 154 far enough that the two will always contact one another when the bar swings forward. In preferred embodiments, catches are located on both sides of the apparatus 100 in order to provide added safety (i.e., higher weight capacity) and stability or balance.
