for stretching & exercise
Just sitting on the ball contracts muscles throughout your body to prevent you from rolling off. The shape allows athletes to perform weight-training exercises at various angles and to train certain muscles through a greater range of motion.
The Gym Ball helps to work core muscles, which include abdominal, mid-back, and lower-back muscles. Weak core muscles can lead to poor posture, which often results in low-back pain. Strengthening those muscles by exercising with the ball may help to relieve chronic lower-back pain.
Users of all skill levels can benefit from the Gym Ball: Beginners can inflate it less, making the ball more steady; advanced users can inflate the ball more, making it more responsive to movement.
