Yoga gym ball/ balance ball is one of the most popular modern fashionable fitness products, which can improve the flexibility and counterbalance, keep fit and strengthen cardio-pulmonary function.

With the skid-proof bars on the surface, the yoga gym ball, which is made of high-intensity and harmless PVC, is as soft as spongy and as pressure-proof as tyres. It is 65 cm in diameter. With the hollow structure, the gym ball is required to fulfill the air with the pump. In such case, the ball can bear a pressure about 100kg, which makes it much more comfortable and safer. Using it as the balance ball chair while resting, it can keep your backbone straight and prevent you from a humpback. Please exhaust gas when store it up.
