A padded cuff secured around the ankle with a D-ring or other attachment point facilitates connection to resistance equipment like weight stacks and pulley systems. This apparatus allows targeted exercises for the lower body, particularly the muscles surrounding the ankle, calf, and hip.
Strengthening these muscles offers numerous benefits, including improved balance, increased power for activities like jumping and sprinting, and injury prevention. Historically, similar principles were applied using simple resistance bands, but dedicated adjustable weight systems provide a more controlled and measurable approach to strength training.
