Brand New and High Quality. Made from premium quality rubber latex and will not over-stretch unlike the cheaper ones. Allows you to tone and sculpt every muscle group. Both for men and women. Ideal for travel and storage. Our resistance tubings are made of professional quality natural rubber latex. It will not recoil and twinge your chest hair as it may sometimes happen with the metal springs. Rubber bands are easily added or removed by snapping on or snapping off action.
