FIELDThe 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.
BACKGROUNDA 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 inFIGS. 1 and 2. This variety of the glute bridge, where the back is elevated with respect to the feet, is often called a “hip thrust.” InFIG. 1, the athlete's back is supported by a bench and his feet are supported by the floor. He is in the down or hip flexed position and an angle of approximately 90° is formed at his hip by his torso and femur. An angle of approximately 90° is also formed at his knee by his femur and tibia (shin bone). InFIG. 2, the athlete's back is still supported by the bench and his feet are still supported by the floor. He is in the up or hip extended position and an angle of approximately 180° is formed at his hip by his torso and femur. However, an angle of approximately 90° is still formed at his knee by his femur and tibia. This approximate 90° angle formed at the knee remains constant throughout the exercise.
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 inFIGS. 1 and 2. However, a disadvantage of performing a weighted glute bridge using a free barbell is that balancing the weight can be difficult, particularly for novice athletes. Additionally, because the motion of the barbell is unrestricted, it may travel along different motion paths from one repetition to the next, which can impact its effectiveness and the consistency of results.
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 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.
SUMMARYThe 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.

DETAILED DESCRIPTIONReferring now toFIGS. 3-6, there is provided anapparatus100 for use in performing a weighted glute bridge exercise according to an embodiment of the present invention. Theapparatus100 generally includes aback support102 and afoot support104, at least one rigidelongate arm106 extending at least partially along the length of the apparatus, ahip bar108 extending at least partially across the width of the apparatus, and at least oneresistance loading area110. To use theapparatus100, a user first assumes the hip flexed positioned by placing his back against theback support102, his feet on thefoot support104, and his hip region under thehip bar108. Next, the user brings his hip region into contact with thehip bar108 and, by pressing his hips upwards, moves from the hip flexed position to the hip extended position. During this motion, theelongate arm106 pivots upwards away from thefoot support104 in a first direction A from a first pivotal position to a second pivotal position. The user then moves from the hip extended position to the hip flexed position by lowering his hips and allowing thehip bar108 to be lowered towards thefoot support104. During this movement, theelongate arm106 pivots in a second direction B from the second pivotal position to the first pivotal position, which completes the repetition.
In the illustrated embodiment, theapparatus100 includes a supporting frame orbase112 that is placed onto a ground surface. The base has a front114, rear116,left side118, andright side120.Risers122 extend generally vertically upwards from the left andright sides118,120 at the rear116 of thebase112. Theback support102 is mounted between the tworisers122 at approximately ⅔ the height of the risers. Theback support102 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 inFIG. 8) that is rigidly mounted between therisers122 and that is covered by a padded outer covering.
Thefoot support104 is a plate-like surface that preferably extends from just in front of thehip bar108 to thefront114 of thebase112. Preferably, thefoot support104 includes afirst end104A and a hingedsecond end104B that is closer to theback support102 than the first end. Preferably, thefirst end104A of thefoot support104 may be raised and lowered about the hingedsecond end104B and fixed in at least two positions.
As shown best inFIGS. 5 and 9, ahinge130 connects thesecond end104B of thefoot support104 to the to the base112 to allow thefirst end104A to be raised and lowered about the second end. One end of acollapsible leg132 is mounted near thefirst end104A of thefoot support104 by anotherhinge130. The opposite end of thecollapsible leg132 is mounted torods134 that extend through each of the left andright sides118,120 of thebase112. Ends of therods134 extend out of correspondingslots136 that are formed in each of the left andright sides118,120 of thebase112 and guide the motion of the rod along the slot and their enlarged ends secure the rod in the slot. When therod134 is positioned at the end of theslot136 nearest thefirst end104A of thefoot support104, the foot support is held at an inclined angle. When therod134 is positioned at the end of theslot136 nearest thesecond end104B of thefoot support104, the foot support is held substantially horizontally. Preferably, in the inclined position, thefoot support104 is inclined approximately 5°-20° from the horizontal position. More preferably, in the inclined position, thefoot support104 is inclined approximately 10° from the horizontal position. In other embodiments, thefoot support104 may be fixed at three or more positions, including a horizontal position and at least two different inclined positions. In still other embodiments, the angle of incline of thefoot support104 is infinitely adjustable.
Preferably, ahandle138 is provided on thefoot support104 to facilitate raising and lowering the foot support. Theslot136 and hinge130 are preferably configured such that pulling upwards on thehandle138 to lift thefoot support104 automatically causes therod134 to slide along the slot and, once the handle is released, to automatically be seated at the end of the slot nearest thefirst end104A of thefoot support104, such that the foot support is held at an inclined angle. To lower thefoot support104, thefirst end104A is first raised and then therod134 is pushed rearward along theslot136 towards thesecond end104B of the foot support. Since bothrods134 are connected to thesame hinge130, which acts as a linkage, moving a rod on one side of the apparatus100 (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 thefoot support104 to be adjusted from either the left or right side of theapparatus100.
Thefoot support104 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 theback support102. As discussed above, thefoot support104 is preferably a plate-like surface. However, in other embodiments, thefoot support104 could be a ground, floor, or other surface. To mimic the elevated hip thrust discussed above, theback support102 andfoot support104 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 theback support102 is raised to a vertical height above thefoot support104 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 theback support102 andfoot support104 may be moved, pivoted, rotated. An example of a pivotingfoot support104 is described below. However, theback support102 andfoot support10 preferably remain fixed in place throughout the exercise in order to provide a stable support surface for the user.
Referring again toFIGS. 3-6, the rigidelongate arms106 are pivotally mounted adjacent a left side or a right side of theback support102 at apivot point124 that is located on the outside surface of therisers122. Due to their being pivotally mounted at one end, the motion of theelongate arms106 is constrained to an up and down circular path about thepivot point124. As a result, the motion path of each repetition of the glute raise remains consistent, which provides more consistent results than the convention glute raise discussed above. It is possible for theelongate arms106 to each pivot about their respective pivot points124 independently of one another. However, in preferred embodiments, theelongate arms106 pivot simultaneously with one another during the exercise. To ensure that theelongate arms106 pivot simultaneously with one another, arigid connection member126 connects the two elongate arms together. More particularly, eachelongate arm106 includes afirst portion106A that is located on one side of thepivot point124 and asecond portion106B located on an opposite side of the pivot point that is closer to thefoot support104 than the first portion of the elongate arm. Therigid connection member126 is connected between thefirst portions106A of theelongate arms106. Thus, the rigid connectingmember126 is spaced sufficiently far enough behind theback support102 that it does not interfere with the user while they perform the exercise.
As shown inFIGS. 3 and 4, thehip bar108 is connected between thesecond portions106B of theelongate arms106 via ahip bar connection140. Thehip bar108 is located between theback support102 and thefoot support104 and is positioned such that it contacts the user's hip region when the user's back is supported by theback support102 and at least one of the user's feet is supported by thefoot support104. The user's hip region remains in contact with thehip bar108 throughout the exercise. When the user moves from the hip flexed position to the hip extended position, theelongate arm106 moves from a first pivotal position to a second pivotal position. When the user moves from the hip extended position to the hip flexed position, theelongate arm106 moves from the second pivotal position to the first pivotal position. In some embodiments, aseparate hip bar108 extends from each of thehip bar connections140 located on the left and right sides of theapparatus100. In that case, each hip bar would contact one side (i.e., left or right) of the athlete's hip region during the exercise. However, more preferably, asingle hip bar108 extends across the width of theapparatus100 and is connected at opposing ends between thehip bar connections140. Thus, a pivoting enclosure that surrounds at least the left and right sides and the front of theback support102 is formed by theelongate arms106 and thehip bar108. When theapparatus100 is equipped with therigid connection member126, it also forms part of the pivoting enclosure and surrounds the back of theback support102. The pivoting enclosure surrounds the user's upper body during the exercise and pivots, as a single unite about the pivot points124.
As discussed above, to perform the exercise, the user first assumes the hip flexed position with his hip region located below thehip bar108. To accomplish this, the user may first step into the pivoting enclosure between theback support102 andhip bar108 and then seat himself on amiddle support142, which may be provided with apadded seat144. Once seated, the user then positions his back against theback support102 and his feet onto thefoot support104, raises his hip region to thehip108, and begins the exercise.
However, more preferably, at least one side of thehip bar108 may be selectively disconnected from at least one of theelongate arms106 in order to provide more convenient access to the pivoting enclosure. For example, in some embodiments, both sides of thehip bar108 may be disconnected from theelongate arms106 via a removablehip bar connection140. In other embodiments, only one side of thehip bar108 is disconnected. For example, as illustrated inFIG. 7, thehip bar108 is provided with a hinged hip bar connection located on one side of the hip bar and a locking hip bar connection located on the opposite side of the hip bar. This hinged and locking hip bar may swing open on one side to provide an opening to allow the user more convenient access to the pivoting enclosure.
More detailed views of the hinged hip bar connection and the locking hip bar connection are provided inFIGS. 10-13. Thehip bar108 swings between an open and closed position. When thehip bar108 is in the closed position, the locking side (FIG. 12) of the hip bar may be removably connected to the adjacentelongate arm106 via a lock. The lock moves between an unlocked position, where thehip bar108 may be pivoted about the hinged side (FIG. 13) to the open position, and a locked position, where the hip bar is prevented from being pivoted about the hinged side to the open position. In this particular embodiment, the lock is formed by a pair oftubes146, including one tube in thehip bar108 and another tube mounted to theelongate arm106, whose open ends align when the hip bar is in the closed position and a slidingbolt148 that slides through the tubes. In the illustrated embodiment, ahandle150 extends through aslot152 formed in one of thetubes146 and connects to thebolt146. To engage the lock, the user aligns the open ends of thetubes146, grasps thehandle150, and slides thebolt148 to the right (as shown inFIG. 12) along theslot152 until a portion of the bolt is located in each of the tubes. To disengage the lock, the user grasps thehandle150 and slides thebolt148 to the left (as shown inFIG. 12) along theslot152 until the bolt is located in only one of the tubes.
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, theapparatus100 is provided with theresistance loading area110, which may be used for applying a resistance force to the user's hip region. Referring again toFIGS. 3-6, theresistance loading area110 is located on theelongate arm106 near thehip bar connection140 such that the resistance force is transmitted to thehip bar108 and is applied substantially directly onto the user's hip region throughout the entire exercise. That resistance force resists pivotal movement of theelongate arm106 as the user extends his hips forward. Applying the resistance force directly over the user's hip region (rather than at some distance spaced away from the hip region) causes the performance of the glute bridge exercise using theapparatus100 to more closely resemble performing conventional glute bridge exercises with a weighted barbell placed across the user's hip region.
Theresistance loading area110 and the type of resistance applied may take many forms. For example, a resistance band could be connected between the elongate arm and thebase112 via hooks that are located on each structure. Alternatively, one end of a cable could be connected to theelongate arm106 at theresistance loading area110. The cable could then be routed to a weight stack using known methods to provide an easily adjustable resistance load. In the illustrated embodiment, theresistance loading area110 is an elongate post that extends laterally outwards from theelongate arm106 and that is configured to receive weight plates.
In order to more closely replicate the feel and performance of conventional weighted glute bridge exercises, theapparatus100 preferably includes a pair ofelongate posts110 that extend laterally outwards in opposite directions from theelongate arms106. These posts are preferably concentrically aligned with the hip bar108 (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-disclosedapparatus100 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 inFIG. 6, certain preferred embodiments of theapparatus100 may include a pivot-limitingleg154 that is rigidly mounted underneath theelongate arm106 and that pivots with the arm. In this particular embodiment, thehip bar108 is indirectly mounted toarms106 by being directly mounted toleg154 viahip bar connection140. The pivot-limitingleg154 automatically limits the distance that the pivoting enclosure can pivot in the second direction B as the athlete lowers his hips to hip flexed position. A first (top) end of the pivot-limitingleg154 is fixedly mounted to theelongate arm106. Theleg154 extends downwards from this mounting location and is sized such that, in the event theelongate arm106 pivots downwards too far (such as during an accidental drop), a second (bottom) end the leg contacts a bearing surface and prevents the arm from pivoting further. Among other things, the pivot-limitingleg154 is intended to prevent thehip bar108 from falling onto and pinning the athlete against thebase112. The bearing surface that the pivot-limiting leg could be a ground surface that theapparatus100 rests on, the apparatus itself, or some other surface. Preferably, the bottom end ofleg154 is protected by apad156, such as a rubberized bumper.
Additionally, in some preferred embodiments, theapparatus100 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 bar108 (and leg154) in a raised position away from thebase112 and the pivoting enclosure at a slightly pivoted position. Having thehip bar108 spaced away from thebase112 facilitates the athlete's entry and exit of theapparatus100. 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 points124. 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 anelongate bar158 having a bottom end that is pivotally mounted to a lower portion of theframe112 to enable the bar to swing rearwards towards theback support102 to an angled and disengaged position. When disengaged, thebar158 is preferably supported by anangled rest160 that is also mounted to a lower portion of theframe112. Thebar158 also swings forward about its pivotal mounting point to a substantially vertical and engaged position. Acradle162 is located on a forward face of the bar158 (i.e., on the side nearest the foot support104). When thebar158 is engaged, thecradle162 is positioned under and vertically supports apost164 that extends laterally outwards from the side of the elongate arm106 (or, in this particular case, theleg154 mounted to the elongate arm106), which supports the pivoting enclosure in a slightly pivoted location.
Thebar158 is mounted between theback support102 and thefoot support104. Preferably, thebar158 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 theback support102 and his feet are on thefoot support104. Therefore, as a safety and convenience feature, thebar158 and post164 are sized and positioned such that the bar cannot swing beyond thepost164. Therefore, in order to swing thebar158 forward, it must be engaged and placed under thepost164. In this case, thebar158 extends upwards past thepost164 and thepost164 extends outward from theleg154 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 theapparatus100 in order to provide added safety (i.e., higher weight capacity) and stability or balance. Additionally, as shown best inFIGS. 8 and 9, alinkage166 extends through thebase112 below themiddle support142 and rigidly connects the two catches together. As such, engaging or disengaging one catch automatically engages or disengages the opposite catch, respectively. Some embodiments may also include ahandle160 for moving thebar158 between the engaged and disengaged positions. In the illustrated case, ahandle160 is mounted at the top of onebar158. In certain embodiments, thehandle160 is removable and may be moved to either the left or right side of theapparatus100 to accommodate user's with either a right- or left-hand preference. In other embodiments, handles160 are located on both the left and right side of theapparatus100.
As shown inFIGS. 14 and 15, the above-described apparatus may100 be used to perform a weighted glute bridge exercise more conveniently, consistently, and safely than conventional methods, such as that shown inFIGS. 1 and 2. InFIG. 14, a user is located in theapparatus100 in the hip flexed position. In particular, her back is in contact with theback support102, such that a portion of her weight is supported by the back support. Next, at least one of her feet is in contact with thefoot support104, such that a portion of her weight is supported by the foot support. Thehip bar108 is in contact with the user's hip region. An angle of approximately 90° is formed at the user's hips by her upper torso and the upper portion of her leg. An angle of approximately 90° is also formed at the user's knee by the upper and lower leg portions on either side of the knee. With thehip bar108 contacting her hip region, the user extends her hips forwards and moves to the hip extended position, shown inFIG. 15, which causes the pivoting enclosure to pivot in the first pivotal direction (counterclockwise in the illustrated views) and thehip bar108 moves upwards away from thefoot support104 andbase112.
InFIG. 15, the user is shown in the hip extended position. An angle of approximately 180° is formed at the user's hips by her upper torso and the upper portion of her leg. An angle of approximately 90° is also still formed at the user's knee by the upper and lower leg portions on either side of the knee. With thehip bar108 contacting her hip region, the user moves back to the hip flexed position such that the pivoting enclosure pivots in the second pivotal direction (clockwise in the illustrated views) and thehip bar108 moves towards thefoot support104. This completes one repetition of the glute bridge or hip thrust exercise.
