Powerball Gyroscope for sports and fitness, carpal tunnel, tennis elbow, tendonitis, wrist pain and grip strength

I just found this amazing little device - known as a Powerball!

It increases resistance, the faster it moves - responding directly to the effort put into it by the person using it.

It seems really effortless, and such a powerfull concept! I must get me one of these!!
