Dynaflex Powerball with Speedometer
The Dynaflex Powerball and Speedometer is a great workout and strength builder and at the same time improves your coordination. It can also be used as an effective way to warm up before sports such as tennis, golf or bowling. It doesn’t need any batteries, instead you get it moving by giving it a quick pull. You then keep it spinning by rotating your hand, and soon it starts spinning at a great speed. This exercise strengthens your grip and the powerball/speedmeter can also be safely used for rehabilitation and medical therapy, especially for carpal tunnel sufferers or as arthritis relief.
The speedometer is designed to work in conjunction with the powerball for ultimate performance. It measures your current speed, remembers your highest rpm as well as calculates your physical strength index. The set was awarded the PGA Partners Club Tested and Approval seal-of-approval.
