TWISTABLE GRIPABLE EXERCISE DEVICE

Abstract

A wrist-grip exercise device is disclosed comprising two partial spheroids interconnected by an elastic central bridge, which partial spheroids may be rotatable axially 90 degrees in opposite directions around a longitudinal axis under the force, with each partial spheroid acting as a graspable handle. In some embodiments the partial spheroids are in the shape of hemispheres. The elastic bridge provides resistance to facilitate exercise and power to return the device to its original shape after being twisted and contorted during use. The elastic central bridge may be an elastomeric polymer material interconnecting the two partial spheroids. In other embodiments the central bridge is a coil spring. In some embodiments the handles are inflatable to facilitate compression grip exercises. In some embodiments the handles are attached to the coil spring by male-female connection system. Another embodiment of the present invention substitutes polyhedrons for the two partial spheroids.
