Although strength training helps maintain bone density some high-impact weight bearing exercises trigger injuries. Using a gliding disc while performing high-impact activities can reduce the risk of an injury. Gliding discs look like frisbees and are placed on the floor to provide a smooth gliding surface for you as you rest your hands and feet on them. It is available in two forms- one for carpets and the other for hard floors. When placed under your hand and feet they can offer a full range of motion. The gliding discs can add a whole new dimension to your fitness regimen.
