ABSTRACT:
A disk is provided with two diametrically opposed handles. A resilient ball is tethered to the center of the disk by a flexible, but substantially inelastic line, said line being slightly shorter than the radius of the disk. Weights may be attached to the device. Proper flexions and extensions of the arms or of other parts of the user's body set the ball in a periodic bouncing motion. The rhythm thus established regulates the various exercises of the user.
