DETAILED DESCRIPTION OF EMBODIMENTS

(5) Throughout the specification, wherever practicable, like structures will be identified by like reference numbers. In some figures, components, such as additional electrical connections or fasteners have been omitted for clarity in the drawings. Unless expressly stated otherwise, the term “or” means “either or both” such that “A or B” includes A alone, B alone, and both A and B together.

(6) FIG. 1 is a depiction of one embodiment of the apparatus for assisting in performing the plank exercise. It includes an annular ring platform 101 and four supports 102, 103, 104, 105. The annular ring platform of the embodiment of FIG. 1 is substantially in the shape of a square, but other shapes could be used. The platform includes a first cushion 106 and a second cushion 107 of substantially the same size and shape. The first cushion and second cushion are spaced apart from each other and generally disposes opposite each other such that there is a void 108 between the first and second cushions. The void allows for one bar to press against the upper sternum and have a secondary support for the lower body while avoiding compression of the soft tissue of the chest which can cause discomfort, particularly for women. In the embodiment of FIG. 1, the annular ring is formed of four bars connected together. Bars 120 and 121 are shown, and the other two bars are substantially the same, but not shown as they are covered by cushions 106 and 107. It should be appreciated that the annular ring could be formed a single unitary piece. For example, one embodiment is a single molded rectangular annular ring, and in such an embodiment, each side may still be considered a separate bar, even though the four sides are seamlessly interconnected.

(7) The cushions are further oriented substantially parallel to each other in the horizontal plane. Generally, the cushions may be wrapped around the bars for ease of manufacturing. For example they may be formed of tubular foam and held in place by a cover having a fastening seam, such as a hook and loop, snap, or zipper seam. However, it is only necessary that the cushions be disposed on the upper surfaces of the bars as the upper surfaces form the contact points with the user. For example, rather than tubular bars, the bars may be flat (or affixed with a flat upper surface) which are then covered in a cushion. The broader flat surface may assist in distributing bodyweight to provide a more comfortable resting position for some individuals. While the embodiment of FIG. 1 depicts the cushions as being the same vertical height (that is, the distance from the bottom of the leg to the uppermost surface of the cushion), it is contemplated that they may be vertically offset such that one is higher than the other. The vertical offset may be achieved by altering the vertical height of one bar supporting one cushion as compared to a second bar supporting a second cushion. In another embodiment, the thickness of the foam of one cushion may be greater than the thickness of the foam of a second cushion. The vertical offset may help facilitate holding the plank position in an inclined state. For example, legs 102 and 105 may be made longer than legs 104 and 103 so as to provide a vertical offset between cushion 106 and 107. In an alternative embodiment, each of the legs are telescopic, as discussed in further detail with respect to FIG. 4. For example, the legs may be made of nesting pipes having a plurality of matching holes. The pipes may be slid in and out of one another and a pin may be slid through the matching holes so as to hold the leg at a set height. The use of legs allows for a user to place their chest on the cushions and grab the legs with their hands for support.

(8) The legs may be irremovably attached to the annular ring. However, in one embodiment, the legs are removable. The four corners of the ring may be formed of multi-point connectors, for example, connector 110 having connection ports 111, 112, and 113. Leg 103 may be inserted and secured into port 113 during use. Leg 103 is adapted to be removable from port 113, and legs 104, 105, 102 are similarly adapted, such that after use, the legs may be removed and the exercise device may be easily transported. Each of the legs may further be equipped with stabilizing feet, such as foot 210 in FIG. 2. It is contemplated that the stabilizing feet may articulate to ensure that the bottom of the foot is able to sit flush to the ground even when one or more legs is oriented at an angle to the ground. It is preferred that the articulation of the feet is such that the legs are not permitted to form an vertical angle of greater than 45 degrees to a horizontal surface so as to keep the center of mass oriented over the feet and preventing the equipment from tipping over under its own weight.

(9) FIG. 2 is a depiction of an alternative embodiment of the apparatus for assisting in performing the plank exercise. It includes an annular ring platform 201 and at least one support 202. It should be appreciated that the support holds the annular ring platform 201 above the ground in a stable manner. While legs are shown the support could alternatively be a solid panel, or a pedestal connected to a base that provides stability. In such an embodiment, the pedestal may include upper branches that connect to the annular ring so as to maintain the void between the first cushion 206 and the second cushion 207. For example the pedestal may be in the form of a Y or U having branches that connect to the bars 208 and the bar opposite 208 (covered by cushion 206 in FIG. 2 for example) that support the cushions. In such an embodiment the platform may be made of just the two separated bars 208 and the bar opposite 208 (covered by cushion 206 in FIG. 2 for example) rather than a fully formed ring.

(10) In the embodiment of FIG. 2, cushion 206 has a width of X.sub.1 while cushion 207 has a width of X.sub.2. In the embodiment of FIG. 2, X.sub.1 is greater than X.sub.2. While not shown in FIG. 2, it is contemplated that cushion 206 and 207 may be vertically offset from one another. Providing an offset where X.sub.1 is vertically higher than X.sub.2 helps facilitate an angled plank position where the upper chest or sternum can comfortably rest on the larger cushion while the upper abdominals can engage and lift the body away from the bar 208 but still rest and balance on the smaller cushion 207. In the embodiment of FIG. 2, bar 208 extends beyond that edges of the cushion 207. The extension allows for a user to feel the bar if the user begins to tilt to one side and may support the user even when the user tilts rather than allowing the user to fall off the side of a narrow cushion.

(11) FIG. 3 is a depiction of an embodiment of the apparatus in a disassembled state. embodiment includes an annular ring 301 a plurality of bars 310, 311, 312, and the bar covered by cushion 323. Each bar further includes a cushion, 320, 321, 322, 323. Each of the legs, shown in a separated state, may be inserted into one of the multi-point connectors, of which connector 110 is exemplary. In one embodiment the legs frictionally engage the multi-point connectors. However, the connections may be threaded or may include a lock. One example of a lock is a system where a leg includes a resilient pin 330. Resilient pin is adapted to be depressed so that the leg may be inserted into a multi-point connector. Once inserted the resilient pin may engage a detent or hole (not shown) to lock the leg in place. The resilient pin may then be manually depressed to release it from the detent or hole such that the leg may be removed.

(12) FIG. 4 is a depiction of an alternative embodiment. It includes telescopic bars 420, 421, 422, 423. The bars telescope into and out of one or more of the multi-point connectors 410, 411, 412, 413. In one embodiment, bars may lock in place, for example through the use of one or more resilient pins that engage with a mating hole. For example, bar connector 413 may have resilient pin 433 and connector 412 may have resilient pin 432. Bar 423 may include one or more holes, such as hole 443 adapted to engage with one of the resilient pins. It should be appreciated that the other bars and multipoint connectors may be similarly structured. In an alternate embodiment, the bars and connectors are threaded so that screwing and unscrewing the bar brings the connectors closer and further apart, respectively. In such an embodiment the threads of the connectors that are adapted to engage either end of the bar are opposites.

(13) The legs may also be adapted to be telescopic. As shown in FIG. 4, leg 403 includes an upper section 450 and a lower section 451. The sections are configured to telescope, and a lock, such as a resilient pin 452 may be adapted to engage one or more holes 453, 454. As shown in FIG. 4, pin 452 engages with a hole (not shown as it is obscured by being engaged by the pin) to lock the leg at a particular height. It should be appreciated that the embodiment of FIG. 4 may further be provided with cushions as in FIG. 1 or 2.

(14) The method of using the apparatus for assisting with the plank exercise is described below. The embodiments may be used in stages to increase strength and endurance. For example, a beginner may start with the embodiment of FIG. 1. First the embodiment of FIG. 1, which may be referred to as the Plank Helper, may be placed on a substantially flat surface, such as the ground. A user places their upper breast bone on the first cushion 106, their lower torso or abdominals (depending on the height of the person) on the separated cushion 107. The person may also place their toes on the ground as well as their hands or elbows (depending on the heights of the cushions). The person then engages their core muscles to lift their lower body away from the ground while allowing a portion of their upper body to remain supported by one or more of the cushions. The person may also grab legs 105 and 102 with their hands for additional support.

(15) As the user gets stronger, the user may adjust the equipment (such as by utilizing the embodiment of FIG. 4) to provide vertically offset bars. In use, the user raises their abdominals away from the second cushion. When fatigue sets in, the user may rest on both cushions. Alternatively, the user may maintain contact with both cushions at all times and engage their core to focus on training muscles to keep good plank form throughout the legs and hips. The user may further use the embodiment of FIG. 2. Once again the user places their chest on the larger cushion and their abdominals on the smaller cushion. The user engages their core to form the plank position. The user attempts to maintain balance over the smaller cushion while keeping good plank form.

(16) The user may further adjust the positioning of the equipment to enhance the difficulty by placing the upper chest on the cushion 107 in FIG. 1, for example. Used in that manner, the user may rest their chin on cushion 106, but more of the user's bodyweight will be extended from the equipment that when the user positions the upper chest on 106 and the lower chest (or upper abdominals) on 107. That increases the difficulty of the plank exercise while still providing support and stability.

(17) Utilizing one or more of the embodiments, a user is able to train to perform the plank exercise and train the supporting muscle groups over sufficient periods of time to gain the benefits of performing the exercise even when their muscles or balance is not sufficient to perform an unassisted plank. The apparatus allows for staged development and reinforces proper plank form.

(18) Although the present invention has been described in terms of various embodiments, it is to be understood that such disclosure is not intended to be limiting. Various alterations and modifications will be readily apparent to those of skill in the art. Accordingly, it is intended that the appended claims be interpreted as covering all alterations and modifications as fall within the spirit and scope of the invention.
