发明名称 Ring shaped exercise apparatus
摘要 A cushioned exercise apparatus is disclosed which preferably includes a single spring steel band or strap coiled into a plurality of spiral wraps forming a circular ring and a pair of handles fastened to the ring. This ring and handle assembly is covered with an enclosing and cushioning layer of rubber or elastomeric plastic material substantially enclosing the assembly and forming a hermetic seal around the assembly to prevent moisture from entering into and damaging the coiled strap ring. The cover also provides a comfortable, cushioning non-slip surface for contact with the user's skin, hands and/or legs during exercise.
