A support garment for use during resistance training. The support garment includes a band of elastomeric material having a front perimeter and a rear perimeter. The front perimeter and rear perimeter are folded together at two points, each point forming a segment. The segments are then affixed to each other at a midpoint. In addition, openings are formed on both sides of the segments with upper arm sleeves encompassing the openings. Each upper arm sleeve is configured for wear on an upper arm of a user above an elbow of the user. The upper arm sleeves are biased inwardly by the attached segments. The user positions one arm in each upper arm sleeve and positions the attached segments across a chest of the user during resistance training.

Exerciser (3) for hanging that can be positioned around a door (16), usable by tall and short persons, having an adjustable bar for hanging (1) which can be easily removed to free the passage through the door. It is meant either for hanging exercises, than for vertebral column stretching. It comprises a bar for hanging (1) supported by two uprights (2,2′) resting on the floor (8) and fixed to a wall (14) with spacers (12). The existence of said two uprights (2,2′) permits: 1) to place the bar (1) also above a door lintel (6), for tall users 2) to removably place the bar (1) internally to the door (16) passage, for short users, thanks to rotating adjusting junctions (18,18′). Therefore this structure does not prevent the use of a door, and permits the user to make brief exercises at any time he passes through the door.

An isometric force resistant exercise tool has a left handle form interfaced to a right handle form over an axle shaft locked to the right handle form, the axle shaft supporting a pressure plate, a compress able spring or set of springs, and a compression adjustment handle threaded onto the axle shaft and abutting the compress able spring or spring set, the pressure plate adjacent in assembly to a friction-resistive material fixed on the left handle form, the left handle form including a piston form interfacing with a ring housing on the right handle form, the piston form adjacent in assembly to a friction-resistive material fixed on the right handle form. Gripping the handle forms and rotating the against force resistance exercises one or more muscle groups.

An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.

An abdominal exercise device includes a frame comprising top, middle, and bottom frame sections. The middle frame section has a curved shape for creating a teeter-totter movement during exercise. The device includes a headrest connected to the bottom frame section, a plurality of connectors for connecting elastic bands to the frame, and an elastic band connected to at least two connectors. The two ends of the elastic band are connected to two straps. The device creates the teeter-totter movement to exercise the abdominal muscles in response to a person lying down in supine position with the back of the head on the headrest and the feet in the two straps, the person applying a downward pressure with the feet to the straps to move the headrest from a resting position, and the person removing the downward pressure to allow the headrest to go back to the resting position.

A motion assist crane device can include a base, a support tower extending upwardly from the base, a counterbalance beam attached to the support tower at a position between the ends of the counterbalance beam by a hinge, a tether attached to a first end of the counterbalance beam, the tether configured to attach to an arm of a user, and one or more weights positioned on a second end of the counterbalance beam. A method for assisting motion of a user's arm can include providing the device, attaching the tether to the user's arm, and moving the user's arm, wherein the movement is at least partially supported by the weights.

A device for training and rehabilitation of a limb is provided. The device provides a board with a plurality of movement tracks to allow for controlled movement of the limb in various directions. Blockers and other controlling structures may be arranged on the device to limit range of motion of the movement of the limb.
