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. It’s one of the most versatile pieces of equipment designed to be inexpensive and productive towards your fitness goals. Suitable for users between 5’ 7” and 6’ 1” tall, the 65cm Premium Gymball has been manufactured with anti-burst material for added safety.
