Abstract
Exerciser for strengthening the grip of the hand having a pair of handles which are removably mounted on the arms of a helical torsion spring in a manner permitting springs having different strengths or resistances to be used interchangeably with the handles. The handles can be constrained against rotation on the spring arms, allowed to rotate freely, or allowed to rotate to a limited degree, depending upon the needs of the user.
