ABSTRACT:
A portable exercise device has a frame which is adapted for the sliding linear motion of plates attached to opposed hand grips. First and second opposed wedges are mounted within the frame, one of which is moved linearly to adjust the compression of perpendicular oriented springs within each of the hand grips. Corresponding slot and pin means are used to prevent linear movement of the hand grips if inadequate perpendicular force is applied. In operation, the device provides both isometric and isotonic exercise.
