The handles are rotatable about their respective longitudinal axes, and they are hinged to the cross-bar at the respective longitudinal axis, and they are hinged to the cross-bar at the respective ends thereof. Each handle, when held by the user, may be turned back and forth pivotally above the corresponding end of the cross-bar with adjustable force adjustment characteristics, and each handle may be rotated about as longitudinal axis with adjustable torque adjustment characteristics.

Abstract: A compact, portable foot/hand hold device used to perform sit-up, leg-raise and other type exercises with the help of any ordinary, interior, walk-through door. The device has two modes: "assembled" and "stored/travel". In the "assembled" mode the device provides a secure, comfortable foot and hand hold for the user while performing several type exercises. Constructed of three simple parts; an anchor, a connecting line and a foot/hand bar, the device assemblies in seconds. It is secured to the door by the anchor. For sit-up type exercises the user places his feet behind the foot/hand bar, one on each side of the connecting line, so that the bar is resting snugly but comfortably in the hollows above the insteps of the feet. His feet are necessarily positioned such that the heels are resting on the floor and the balls of his feet are pressed firmly against the vertical plane of the door.

Abstract: A stretching machine for performing the Chinese split includes a base, two generally horizontal tracks extending colinearly from the base, a foot platform sliding on each track, and a vertical column with handles. The user stands on the platforms, which travel outward from the base while the split is performed, and maintains balance by holding the handles. The platforms are moved along the tracks by cables fixed to either side of each platform. The cables run over pulleys to a drum mounted in the column, which can be turned by a crank. A novel aspect is a slight angular inclination between the tracks, allowing a deeper split.

Abstract: A low row exercise machine includes a frame, a seat and chest support connected to the frame along a vertical midplane, and a paiar of levers with first ends pivotally connected to the frame above and in front of an exerciser supported on the seat. Each lever includes an intermediately located hub for holding a selectable weight resitance and a handle located at a second, lower end thereof adapted to be grasped and pulled rearwardly through a low row exercise motion by an exerciser supported on the seat. The levers pivot through planes which converge with respect to the forward facing direction of the exerciser. The orientation of the frame, the seat and the levers, and particularly the convergence of the levers and the angles of connection of the handles with respect to the levers readily accommodate the natural musculoskeletal makeup of the human body during the performance of a low row exercise motion, thus maximizing the muscular benefit attainable through performance of this exercise motion.

Abstract: A kinesthetic diagnostic and rehabilitation device enables the user to measure the extent of kinesthetic impairment resulting from a bodily injury, particularly an injury to the lower limbs, and also enables the user to rehabilitate the injury. The device is provided with a rigid platform resting atop an unstable support. The ability of the patient to maintain a fixed position on the platform as a function of the instability of the support enables quantification of the patient's kinesthetic impairment. The device further provides rehabilitative exercise.

Abstract: A treadmill equipped with a pair of spring loaded handles that allow the user to exercise the arms and shoulders while walking on the treadmill surface. The handles can be mounted in different rotative positions on stub shafts so that they can be oriented to meet the desires of the user. Pivotal movement of the handles is resisted by compression springs mounted on rods which slide axially when the handles are pivoted back and forth.
