These foam balls are ideal for strengthening the muscles in your hands and forearms. Since they have no bounce, they can also be used for throwing, catching, and handling exercises. Squeeze the ball with your hands and then release it; within a few seconds, it returns to its original shape. Stress balls in school can help children focus better on tasks and increase concentration.
