Contours to snugly fit the ankle, wrist and thigh. Its Velcro® closure strap assures a secure and comfortable fit… even during the most strenuous exercise program. Features heavy-duty materials and double stitching throughout. Color-coded, marked with pounds and kilograms and grommeted for hanging on any weight rack. Other features include: An extra-long loop adjustment strap that permits the weight to be used for larger appendices like the thigh and two added hook tabs. The loop strap can adhere to these added tabs to prevent the strap end from getting in the way when the weight is used for arm and leg exercises. Sold individually.
