Gliding discs look similar to frisbees and are used on the feet and hands to provide a smooth gliding surface. Use these workout discs to lengthen and strengthen all the major muscle groups in your body through engaging their full range of motion. Gliding discs can help to tone the inner and outer thighs, sculpt the legs, and can firm and lift the buttocks. And because your hands and feet never leave the floor while using the discs, it is a low-impact workout that is especially useful for those who have had a recent injury or who have joint pain.
