发明名称 Aquatic exercise device
摘要 An elastomeric band exercise device is modified by adding a cushion to the band to permit it to be comfortably stepped on with a bare foot without discomfort. The modification is particularly advantageous when the device is used in performing aquatic exercises. Each handle has a waterproof friction grip covering a steel weight bar. The handle is connected to the band by a retainer ball in the end of the band and a washer inserted between the ball and a throat in the handle through which the band is extended.
