ABSTRACT:
Exercise apparatus has a handle attached to a cable which is extended when tension on the cable exceeds a preset value. A release allows the cable to be moved effortlessly to the starting position of the exercise. The cable is retracted when the cable is slack, and the cable is clamped at a desired position and a signal emitted when the tension in the cable exceeds a preset value. The exercise apparatus has an isometric mode which allows a force to be applied to the cable without motion of the cable.
