1. Quick and flexible: The 2 foot cuffs can be attached to the cable machine quickly and easily. The Velcro fastener makes the foot straps flexibly adjustable and allows a one-size-fits-all for men and women. 2. Tone and strengthen lower body muscles: Kickback ankle straps help you target calves, lower legs, lower body and even glutes to tone, strengthen and tighten muscle groups to create a leaner, stronger body. 3. Versatile training routines: Gym ankle straps can be used with most standard cable systems, functional and resistance trainers and similar equipment for leg extensions, leg curls, hip abductors and glutes. 4. Strong, stable resistance: We use a sweat-resistant, breathable neoprene ankle cuff that is gentler on the body, reinforced double D-ring in steel and double stitching to ensure long-lasting equipment strength and wide attachment comfort. 5. Classic colors: These ankle straps for men and women are also available in both singles or pairs as well as a variety of fun colors you will love.
