Gym Ball is a simple and versatile fitness tool designed to encourage continuous movement.

Challenging and fun for all ages, the Gym Ball can help you strengthen and tone muscles, improve balance and coordination, and stretch to increase flexibility.

Inflates easily with an included handy quick-air pump. Durable and manufacturer guaranteed not to leak or puncture with normal use.

Also, because the FitBall is not stable, it forces you to keep an ideal posture. In fact, ideal spinal posture is the easiest to balance with, and can decrease your back pains over time.
