Stackable weight plates comprised of a front and a rear lateral faces with a protrusion at a proximal radial center of the front lateral face and corresponding recess at a proximal radial center of the rear lateral face is provided. The rear lateral face with the recess section at the proximal radial center of a top weight plate in a stack may rest (or be stacked) on the front lateral face with the protrusion at a proximal radial center of another weight plate. Because each plate is restrained along its center axis by the mating or interlocking of the protruded area of one plate with the recessed area of another weight plate, the stacked plates are therefore generally stable and do not fall due to lateral shearing of the stack. When mounted on a handle bar to form an inertial force exercise device, the recessed area of the rear lateral face of the weight plates of the present invention house the mounting or fastener mechanism.

The portable device (10) for rehabilitating an impaired user having difficulties in executing simultaneous reaching and lifting tasks comprises an armrest (12) whereto the forearm of the user can be fastened and means (16) for enabling the movement of the armrest on a surface. It furthermore comprises means (18) for monitoring the movement of the armrest and means (13) for sensing a force exercised by the arm of the user in an orthogonal direction to the surface. The device enables the user to conduct reaching movements in a large workspace having the forearm supported and fastened. The fact that the forearm is supported and fastened to the device allows for better control of the shoulder training movements, avoiding uncontrolled trajectories at the level of the elbow that are possible in case only a handle is grasped.

A resistance module for an exercise machine for providing a substantially constant force through a range of motion includes at least one cantilever spring and at least one rigid member movable with respect to one another along a path of travel. The rigid member causes the cantilever spring to deflect and produce a resistance force. The cantilever spring has an anchored end and a deflection end. The rigid member engages the deflection end of the cantilever spring, and constrains the deflection end to a predetermined path of deflection as the cantilever spring and the rigid member move with respect to one another. The rigid member can be a non-planer contact surface along which the deflection end tracks, or a pivot link. The module can include means for operatively coupling at least one of the cantilever spring and the at least one rigid member to an exercise machine.

The present invention is a portable isometric exercise device with resistance generated by a spring force including an electronic light or sound indicator to signal that a constant force level is being maintained. When a force is applied to the spring and a desired level of resistance is achieved, a continuous signal will be generated to advise the user that the isometric force exercise is being maintained. If the force is reduced, the signal will terminate to advise the user that the user has not maintained the required level of resistance.

The present invention uses an inertial force exercise device comprised of an ergonomically snug grip handle bar, racking collars on either side of the handle including head plates in combination with a storage racking system that enables appropriate mating with the racking collars of the inertial force exercise device.
