Inside the Spaceball Armtrainer rotates a ball, which is kept in motion by muscle power. The gyroscopic force can target different muscle groups, depending on the posture of the grippy little ball. All people who wish to train their hands and arms can easily strengthen wrists, lower and upper arms with the Spaceball. Athletes like golfers, boxers, tennis players but also climbers use the training effect of the hand trainer.
