The Body Sculpture Adjustable Balance Board is ideal for increasing core strength and overall strength. It is adjustable, meaning you can change the height of the board to three different levels - 6cm, 8cm or 9.5cm. The higher the board, the greater angle of movement that can be achieved (16°, 23° or 27°) and the harder your core needs to work. Great for toning and muscle strengthening. The wobble board has a good diameter of 16 inches, meaning it will be suitable for users of all sizes and ability.
