A gym ball has to offer a fine balance between support and instability, if the ball is too rigid or too soft then the effects on your core stabilising muscles will be compromised. The adidas Gym balls all perform to these optimal levels.
This particular Gym ball has been manufactured with anti-burst material for added safety and features a dual texture grip for extra stability.
Enhancing the effects of your daily workout, the gym ball is used to keep the balance, with the body working different muscle groups that wouldn't be active while exercising on a flat surface. Suitable for sit-ups, back exercises, stretching and resistance work, the adidas Gym ball is a must-have fitness accessory in your collection and comes with the necessary hand pump.
