Abstract: An exercise device includes two hand-held grips that generate a pneumatic force that opposes reciprocating movement. Each hand-grip has a piston that moves within and relative to a cylinder. An air outlet associated with each cylinder can be adjusted to adjust the pneumatic force generated by reciprocation. The higher the pneumatic force, the more work is performed to reciprocate the hand-grips.

Abstract: A collapsible treadmill includes a base, a pivot seat at a front portion of the base, an upright bar mounted in the pivot seat, a securing bar fixedly disposed on the upright bar, and two grip bars. The grip bars are locked to the securing bar at their top ends and to the base at their bottom ends. When the treadmill is not in use, the grip bars and the upright bar may be lowered in the direction of the base so as to reduce the size of the treadmill as a whole for easy storage.

Abstract: A body-building machine includes a locating frame having an head portion integrally formed at a top thereof. The head portion defines an open chamber and a pair of opposed holes at two side walls thereof. A locating plate having an inclined end portion is inserted into the open chamber and is received in the locating frame. A pair of tubular lugs are formed at an intersection between the locating plate and the inclined end portion, aligning with the pair of opposed holes. A cladding plate having a plank with an angled portion is received in the open chamber. A tube is formed at an intersection between the plank and the angled end portion, aligning with the tubular lugs. A shaft extends through the opposed holes, the pair of tubular lugs and the tube to engage the locating plate with the plank and to form a short tension arm above shaft and a long tension arm below the shaft. An elastic return mechanism is disposed between the inclined end portion and the angled end portion in the short tension arm portion.

Abstract: The present invention provides an exercise bar for use in rehabilitative therapy of joint structures, especially those of an impaired limb of a user. The exercise bar preferably comprises an elongated shaft having a longitudinal axis and two ends, a loop member comprising a loop attached to a first end of the shaft, and a handle member attached to a second end of the shaft at an angle to both the longitudinal axis of the shaft and the plane defined by the loop of the loop member. The loop preferably is in the shape of an isosceles triangle with the angles forming arcuated notches for receiving a portion of the user's impaired limb. Once the user's limb is seated within one of the notches, the shaft may be rotated about it axis to enable rotational, resistive stretching of a first joint complex or may be reciprocated along its axis to enable the performance of various exercises.

Abstract: A wrist exerciser has a pair of coaxially mounted hand grip bodies. The hand grip bodies can be counter-rotated against a resistance to exercise the muscles in a user's forearms. A friction disk is sandwiched between the two hand grip bodies with a friction surface on one of the bodies bearing against the friction disk. The two hand grip bodies are biased toward each other to clamp the friction disk. The amount of bias force can be varied to set the amount of resistance to the rotation of the hand grip bodies relative to each other. The exerciser includes a spring connected to a member which is slidably mounted in a bore within one of the hand grip bodies. The member is prevented from rotating in the bore. The position of the member can be adjusted by turning an adjustment knob which is threadedly engaged with a threaded rod extending from the member. The bearing is located at one end of the spring. A thrust bearing between the adjustment knob and the hand grip body makes the adjustment knob easy to turn.

Abstract: A multipurpose exercise device includes a stiff bar terminating in limb engagement members and a flexible element connected to the center of the bar, extending away from the bar and being provided with its own limb engagement members. The bar can be positioned so that it engages the feet and the flexible member can be positioned to engage the hands or vice versa to perform a large array of exercises. Preferably the flexible member is elastic.

Abstract: Exercising the wrist and hand of an individual is achieved solely by the individual by anchoring the hand to a fixed support with the palm facing upward and the thumb and fingers free to move. The individual then grasps the thumb of the secured hand by the other hand and pushes the thumb laterally outward and toward the fixed support, thereby stretching the muscles, tendons and ligaments of the hand. Anchoring the hand to a fixed support is achieved by use of a C-shaped clamp, with one open end engaging the underside of the fixed support and the other open end engaging the palm side of the hand in the area between the carpal wrist bones.
