Leverage Discs® are patented air-filled discs specifically designed to improve lower body stability and joint strength during rotational movement patterns. The unique “hole in the middle” design allows for optimal foot positioning to emphasize compression against the ground to help develop powerful rotational movements. Leverage Discs are especially beneficial for sports like golf, tennis, hockey and baseball. Leverage Discs are being used by PGA Tour players and Major winners and NFL teams. U.S. Patent #8,133,125.
