| TenniSpheres are hand exercise balls. They can be used to strengthen the hand, wrist, and warm and for general stress relief. Hand exercise ball are used as tools by sports trainers, physicians, musicians and artists for the development of finger dexterity, hand and arm strength, and general conditioning of the hand, wrist and arm.
TenniSpheres are an innovative product based on an ancient hand exercise technique. Two iron balls are manipulated in the hand(s) with various motions. The exercises are believed to have beneficial effects not only for the hand, wrist and arm, but for the whole body. Relaxation and stress relief is probably the main claim to fame. TenniSpheres do NOT have "chimes" like traditional hand exercise balls, which allow them to be used without annoying others. Use them on airplanes, at home watching TV, or even during a meeting. |
