Abstract: A muscle enhancement device having two elongated tubes telescopically engaged with one another so that a first of the tubes slides axially within a second of the tubes. A spring is positioned within the second tube so as to bias the first tube to normally extend outwardly away from the second tube. The first tube provides a horizontally oriented, curved contact force distribution means designed to be positioned in contact with a surface, such as the abdomen, and the second tube provides an elongate horizontally oriented handle designed to be grasped in the hand. Thus, to exercise a muscle group such as the abdominals, the user simply positions the curved force distribution means against that portion of the body and pulls the handle toward the body with enough force to compress the spring between the two tubes. A visual monitoring means allows the exerciser to see how far each cycle of exercise motion progresses so as to motivate and control the exercise in terms of difficulty and consistency.

Abstract: A ski-type exercise or therapy apparatus for use with liquid contained within a pool having walls utilizes a frame positionable in a stationary condition with respect to the walls of the pool and a pair of pump assemblies wherein each pump assembly includes a piston and a cylinder within which the piston is slidably received for movement therealong in conjunction with the movement of a corresponding foot of an individual between two positions of movement. A port provides flow communication between the interiors of the cylinders so that as the piston is moved along the cylinder in conjunction with the motions of the individual's foot during an exercise or therapy routine, liquid flows between the interiors of the cylinders by way of the port. By controlling the flow of liquid between the interiors of the cylinders by way of the ports, the motions of the individual's feet during the exercise or therapy routine can be controlled.

Abstract: A hand developing device comprises two handles, one elastic element and one adjusting member. The two handles are so pivoted together at one end thereof as to form a pivoting point serving as a fulcrum on which the two handles turn. The elastic element is disposed between the two handles such that the elastic element can be forced out of shape by the pressing portions of the two handles so as to bring about a damping effect.
