Reebok 65cm Stayball

Finally a stablility ball that you don't have to chase. With the growing popularity of Pilates, yoga and stretching classes, the use of exercise balls is increasing. However, many consumers are still intimidated by working out on a large rolling object. The Reebok Stayball offers an innovative solution to the problem. The StayBall's breakthrough design enables the ball to stay in place, so users can safely change positions and perform the exercises. No more chasing the ball across the room or awkwardly fumbling to complete a workout. However, the StayBall maintains the key function of an exercise ball -- engaging core muscles with its dynamic surface. Using the StayBall strengthens the core muscles -- the source of good posture, balance and stability. The same revolutionary innovation that keeps the StayBall in place also allows consumers to use the ball as a 5 pound weight. The StayBall gives the simpliest exercise the added resistance necessary to get the most out of a workout. The StayBall comes in 2 sizes 55cm and 65cm accomodating users of all heights.
