The Reebok 55cm Women's Training Stability Gym Ball features a weighted base which provides extra grip to prevent the ball from following away during exercise. It is ideal for training strength, flexibility, balance and fitness in general. The weighted base also provides an extra challenge when performing various exercises for more intense workouts.

The stability exercise ball is manufactured with high density rubber which ensures longevity and features anti-burst technology which means in the event of a puncture, the ball will deflate slowly and safely. A pump is included as well a workout DVD to help kick-start your training. The 55cm ball is most suitable for users between 5'1" and 5'6" tall.
