A hand exerciser device, comprised of a body having a thumb opening, a plurality of finger openings spaced apart from the thumb opening, and a central enlarged portion interposed between the thumb opening and the finger openings where the body is fabricated from a gelatinous elastomeric composition having both sufficient stretchability for extension of the hand exerciser device by opposing pressures applied by the thumb and at least one finger and sufficient resistance for compression of the hand exerciser device by cooperating pressures applied by the thumb and at least one finger and also returning to the original shape with release of the pressures, even after extensive repeated extending and/or flexing.
