ABSTRACT:
A self-contained, hand held and operated exerciser for the hand, wrist, arm, shoulder, chest and back muscles is disclosed. A pair of spaced parallel handles having freely rotatable gripping pads are biased apart by main torsion springs anchored to the handles near their ends. The main torsion springs are restrained by substantially rigid keepers and allow lateral displacement of the handles toward and away from each other over a limited distance during use of the exerciser. Supplemental torsion springs increasing the ability of the exerciser to resist forces exerted on it are conveniently installed and removed without the necessity for fastener elements or the use of tools.
