Abstract: A portable exercise device that uses a single centrally located bungee to provide equal tension on both sides of a user's back. A seat attachment strap secures the device to a seat back. In one embodiment, an optional pad worn by the user is secured to a tension strap which is attached at its ends to the bungee. The tension strap is held in place on the seat attachment strap by retaining straps mounted on the seat attachment strap. To exercise the abdominal muscles, the user leans forward causing the single tension cord to exert equal pressure on the side straps thereby exercising the abdominal muscles. By reversing position, the user may exercise back muscles by leaning backward, or exercise chest and arm muscles by pushing against the seat back with the user's arms. An alternative embodiment uses a chest strap that is centrally attached to the tension strap by a centrally located attachment strap. Another alternative embodiment attaches the tension strap directly to the chest strap.

Abstract: The invention is combination arm exercise apparatus and propulsion aid for a wheelchair. Typically, a wheelchair user pushes a wheelchair using the triceps, pectorals, and deltoids, exercising these muscle groups extensively without exercising the opposing muscle groups: the biceps, the trapezius, and the latissimus dorsi. The invention is an elastomeric member connected at one end to a strap around the user's wrist, and at the other end to a pivoting arm attached above the footrest of a wheelchair. The invention exercises the biceps, the trapezius, and the latissimus dorsi when stretched, and assists the triceps, pectorals, and deltoids in pushing the wheelchair forward as it retracts. The invention hereby balances the level of exercise for the opposing muscle groups as it helps move the wheelchair forward.
