The Wrist Gyro Ball is a hand and arm strength builder. Made of a transparent green plastic, it consists of a 2-1/2 inch diameter hollow ball with a yellow plastic gyroscope inside it. The gyroscope has a channel that runs along its axis. Included with the ball is a thin red cord. One end of the cord is inserted into a hole in the channel. You then wrap the cord along the channel and then give it a sharp pull to start the gyroscope spinning.
Once it starts spinning, you rock your hand back and forth left to right to increase the spin. If you do it correctly, the gyro will rev up faster and faster making it harder and harder to hold on to the ball. As the spinning increases, so does resistance and the feeling that the ball is going to just fly out of your hand. As a result, you have to keep a tight grip which helps to strengthen your hand, fingers and forearm. This ball also has flashing red led's that will light up when the ball starts spinning at a certain speed.
Using gyro balls have proven to benefit people with arthritis and carpal tunnel syndrome.It can also help to strengthen your grip for things such as golf, tennis, guitar playing, etc.
Regardless, it is actually fun after you get the hang of it and can be done sitting, standing, while you watch TV or talk on the phone.
