The Grafco Wrist and Ankle Weight series is designed to provide progressive resistance for physical therapy, rehabilitation, and general fitness. These weights feature a color-coded system that allows for easy identification of different resistance levels at a glance. Each weight is constructed from heavy-duty, reinforced vinyl that is easy to wipe clean, and the long hook-and-loop closure strap ensures a secure and comfortable fit on either the wrist or ankle (except for the 1 lb model which is wrist-specific).
