As you use Baoding Balls to exercise and improve dexterity in your hand, you may be interested in an exerciser capable of more resistance. The powerball is the high tech version of a hand exercising ball. The ball is about the size of a tennis ball and contains a balanced gyroscopic exerciser. As you rotate the ball with your wrist, the gyro inside the ball creates a gyroscopic force generating heavy resistance against your hand, wrist, arm, and upper body. You control the amount of resistance by altering the speed of rotation. The powerball makes a great tool and has been used by physiotherapists for rehabilitation and sport trainers as a training aid.
This video shows a demo of the powerball. It comes with a string to pull start the ball, but the person in the video is skilled enough to start it with his thumb.
