Abstract: An abdominal exercise device includes a first U-shaped frame member pivotally attached to a second U-shaped frame member. Each frame member includes a pair of spaced parallel legs and a cross section extending therebetween. A head rest is mounted on the cross section intermediate the legs of the first frame member. An adjustable pivot tube is telescopically mounted within each leg of the first frame member to adjust the length of the legs. The legs of the first and second frame members are pivotally attached to each other generally adjacent the free ends thereof. A pair of spaced flexible straps extend between the cross sections of the frame members. A spring-biased detent pin is mounted within the hollow interior of each of the legs of the first frame member and is selectively engaged in holes formed in the legs of the first frame member to provide linear adjustment to the first frame member.

Abstract: A low-impact aerobic exercise device includes a base which supports a generally vertically extending frame member and an angularly extending brace member. Two spaced levers are pivotally mounted to the vertical frame member and have pedals mounted on their outer ends for independent reciprocal pivotal movement when used as a stair-stepping type of exercise device. Two resilient elastomeric members are adjustably attached between the brace member and the two levers to provide vertical downward resistance when the user pivotally oscillates the levers in an up-and-down motion. A handle is attached to the vertical member for grasping by the user. An insert can be removably mounted between the lever pedals to provide a single continuous platform joining the two levers, enabling the lever to be used as a rebounding type of exercise device. The frame member is pivotally attached to the vertical frame member, enabling the device to be moved to a compact collapsed position for storage.

Abstract: An exercise device for performing a variety of resistance exercises for toning various parts of the body. A rigid one-piece frame member has a substantially "H"-shaped configuration with a central support and two pairs of outwardly extending spaced parallel rails or leg members terminating in outer open ends. Elastic bands extend between the spaced rails and across the end openings. A user performs various arm and leg exercises by selectively pushing in or pulling out on the bands.

Abstract: An exercise apparatus as described and includes a support, a lever arm pivotally mounted to the support adjacent a first lever end. An exercise fitting, such as handle bars and other linkages, are placed adjacent a second end of the lever arm for allowing pivoting of the lever arm. Weights are movable along the lever arm a distance between the first and second ends and such that the movement has a horizontal component with respect to the support. A motor is provided for moving the weights.
