The exercise apparatus of the present invention allows an exerciser to do more push-ups or bench press repetitions than the exerciser could do without using the exercise apparatus. The exercise apparatus comprises an elongated elastic center region for resting against the chest of the exerciser and right and left arm cuffs for wrapping around a portion of the arms near the elbow of the exerciser. The center region may be disposed against the chest during exercise. The exerciser inserts his or her arms into arm cuffs of the exercise apparatus with a central portion of the apparatus across the chest of the exerciser. As the exerciser lowers the barbell towards his chest during a bench press, the central region and the arm cuffs of the exercise apparatus stretch, and as the exerciser lifts the barbell away from his chest the exercise apparatus contracts to thereby assist in the lifting of the barbell. Similarly, during push-ups, as the exerciser lowers his body toward the ground, the central region and the arm cuffs of the exercise apparatus stretch, and as the exerciser pushes his body away from the ground the exercise apparatus contracts to thereby assist in the lifting of his body.
FIG. 1 is a perspective view of an exercise apparatus 100 according to the innovations herein. The exercise apparatus 100 comprises an upper elongate member 102 and a lower elongate member 104. The upper elongate member 102 has a substantially rectangular shape with ends 110 and 111 and sides 112 and 113. The lower elongate member 104 has a substantially rectangular shape with ends 120 and 121 and sides 122 and 123. The side 113 of the upper elongate member 102 is attached to the side 122 of the lower elongate member 104 to form an elongate member having a substantially rectangular shape. The sides 113, 122 may be attached to each other by sewing using a polyester thread. The upper elongate member 102 and the lower elongate member 104 are folded at both ends with the ends 110 and 120 attached to the upper elongate member 102 and the lower elongate member 104, respectively, to form an arm cuff 130 and the ends 111 and 121 attached to the upper elongate member 102 and the lower elongate member 104 to form an arm cuff 131. A central portion 132 is formed between the arm cuffs 130, 131. The ends 110, 111 and the ends 120, 121 may be attached to the upper elongate member 102 and the lower elongate member 104, respectively, by sewing using a polyester thread.
The arm cuffs 130, 131 are configured to encircle the right and left arms, respectively, of an exerciser. Each arm cuff 130, 131 is configured, shaped and sized to encircle the arm of the user in the area adjacent to and including the elbow, for example, between a point on the forearm below the elbow of the arm and a point on the upper arm above the elbow. The arm cuffs 130, 131 may be have a width selected based on the size of the exerciser or the exercise. The arm cuffs 130, 131 may be tapered so that the upper part of the cuffs 130, 131 are larger to accommodate large biceps and triceps. The arm cuffs 130, 131 may be contoured to accommodate the changing width of the upper arm and lower forearm.
Slots 140 and 141 are formed in the arm cuffs 130 and 131, respectively, between the upper elongate member 102 and the lower elongate member 104 to form openings to allow the exerciser to grasp the arm cuffs 130, 131 while putting on or taking off the exercise apparatus 100. In some embodiments, the slots 140 and 141 are formed by not sewing portions of the side 113 of the upper elongate member 102 to corresponding portions of the side 122 of the lower elongate member 104. In other embodiments, the slots 140 and 141 are formed by sewing the side 113 of the upper elongate member 102 to the side 122 of the lower elongate member 104 and cutting portions of the sewn sides to form the slots 140, 141. The edges around the slots 140, 141 may be sewn for reinforcement. In some embodiments, the upper elongate member 102 and the lower elongate member 104 are formed as a single member and the slots 140, 141 are formed by cutting openings in the single member.
The central portion 132 has a length sufficient to extend across a chest of the exerciser and for the first and second arm cuffs 130, 131 to encircle the right and left arms, respectively, of the exerciser. The central portion 132 may be have dimensions selected based on the size of the exerciser or the exercise. In some embodiments, both the upper elongate member 102 and the lower elongate member 104 have a length of about 45 inches and a width of about 4 inches. In various embodiments, both the upper elongate member 102 and the lower elongate member 104 have a length of about 36 inches and a width of about 3 inches. The arm cuffs 130, 131 have a loop inner diameter of about 12 to 16 inches. The arm cuffs 130, 131 may be formed with various sizes, such as small, medium, large, extra large (XL), extra extra large (XXL) and triple extra large (3XL).
In other embodiments, the arm cuffs 130, 131 are formed separately from the central portion 132 and are attached to the central member 132. In various embodiments, the arm cuffs 130, 131 are detachable from the central portion 132, and fasteners or other attachment apparatus provide sufficient force for maintaining the attachment of the arm cuffs 130, 131 to the central portion 132 during exercise.
In some embodiments, the upper elongate member 102 and the lower elongate member 104 are formed of an elastically yielding, stretchable, and shape restoring material. The material may permit repeated deformations within a defined range without degrading its elasticity. In some embodiments, the upper elongate member 102 and the lower elongate member 104 are formed of a material that is elastic in a longitudinal direction and is substantially inelastic in a transverse direction. The upper elongate member 102 and the lower elongate member 104 may be, formed of an elastic material, such as elastance (spandex or lycra), or a nylon supportive material. The type, properties and characteristics of the elastic material may be selected based on a desired assistance level for the exercising. In some embodiments, the elasticity of the upper elongate member 102 and the lower elongate member 104 provides an increase of about 10 to 20 percent in weight for bench pressing, or about 10 to 20 percent of bodyweight assistance for push-ups.
Although the central portion 132 has been described as being formed of a single layer, in some embodiments, the central portion 132 may include one or more layers of elastic material. In various embodiments, an elastic member (e.g., elastic webbing, or cord or tubing, such as surgical tubing) may be disposed between the layers or on a layer.
During exercise, the exercise apparatus 100 may mimic natural muscle movement, by lengthening and shortening with the muscles to provide support during the eccentric and concentric phases of a bench press or push-up to thereby reduce stress on the shoulders, elbows, and chest.
FIG. 2 is a drawing illustrating an exerciser wearing the exercise apparatus 100. For push-ups or bench press, the exercise device 100 is put on and worn in the same manner. The exerciser places an arm through one arm cuff (e.g., arm cuff 130), and slides the arm cuff 130 up the arm so that the arm cuff 130 covers the lower bicep and the upper forearm with the elbow near the center of the arm cuff 130. The arm cuff 130 should be secure on the arm. The slots 140, 141 may be used to grasp the exercise apparatus 100 for pulling the apparatus 100 up the arm. The exerciser repeats the process for the other arm cuff (e.g., arm cuff 131). The exerciser may put on the exercise apparatus 100 without the assistance of a training partner. The exerciser should select a size of arm cuffs 130, 131 so that the exerciser may install the exercise apparatus 100 without assistance.
FIGS. 3 and 4 are drawings illustrating an exerciser using the exercise apparatus 100 while bench pressing. As shown in FIG. 3, the exerciser lays on a bench, and grabs and holds the bar in a similar manner as the exerciser would bench press without using the exercise apparatus 100. As the exerciser lowers the bar, the arm cuffs 130, 131 and the central portion 132 stretch. As shown in FIG. 4, the exercise apparatus 100 is stretched across the chest of the exerciser and the arm cuffs 130, 131 below the front of the chest of the exerciser. The stretched exercise apparatus 100 provides a force to contract to thereby assist the exerciser in lifting the bar as the exerciser lifts the bar. The exercise apparatus 100 may be used for various forms of bench presses, such as flat bench press, incline bench press or decline bench press.
FIGS. 5 and 6 are drawings illustrating an exerciser using the exercise apparatus 100 while doing push-ups. As shown in FIG. 5, the exerciser assumes the start position of a push-up with arms extended and hands on the floor in a similar manner as the exerciser would prepare for push-ups without using the exercise apparatus 100. As the exerciser lowers his body, the arm cuffs 130, 131 and the central portion 132 stretches. As shown in FIG. 6, the exercise apparatus 100 is stretched across the chest of the exerciser and the arm cuffs 130, 131 above the front of the chest of the exerciser. The stretched exercise apparatus 100 provides a force to contract to thereby assist the exerciser in lifting his body as the exerciser pushes his body upward. The exercise apparatus 100 may be used for various forms of push-ups, such as normal push-ups, decline push-ups or push-ups with various hand spacing.
While particular embodiments and applications of the present invention have been illustrated and described herein, it is to be understood that the invention is not limited to the precise construction and components disclosed herein and that various modifications, changes, and variations may be made in the arrangement, operation, and details of the methods and apparatuses of the present invention without departing from the spirit and scope of the invention as it is defined in the appended claims.
