A gymball 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 gymballs all perform to these optimal levels even if you are simply using the ball to sit on at a desk or performing dynamic exercises. 65cm diameter gym ball. Anti-burst material. Dual grip texture for extra stability. Hand pump included. Maximum user weight 110kg (17st 5lb).
