Dyna Flex Powerball Amber Gyro Ball
Price: $34.95
| Addictive fun and arm and wrist strengthening to boot. We put a Power Ball in the Warehouse, and soon everyone wanted to try it. Exercise with the Power Ball is started by spinning a gyroscope inside the Power Ball. By rapidly rotating your wrist, the gyroscope gains speed, placing torque on the muscles in your arm and hand. Once perfected, the Power Ball provides a solid workout. |
