By Xpeed
The Commercial Gym Balls by Xpeed are a durable ball that can handle high use and significant weight. Why do they work? The main benefit of exercising with a gym ball is that the body responds to the instability of the ball to remain balanced, creating a greater activation of core muscles, which can result in improved back and spine health, core stability, posture and muscle balance. Even simply sitting on the ball activates the stabiliser muscles and helps you connect with your centre of gravity.
