Ankle cuffs are devices used to secure an individual's ankles, often made of materials like leather, nylon, or metal. They are commonly associated with law enforcement and security settings, where they help restrain a person's movement. Ankle cuffs can also be used in various sports and fitness activities to enhance workouts by adding resistance. In addition to their use in security, ankle cuffs are sometimes found in rehabilitation settings, where they assist in physical therapy exercises. They can also be used in fitness training to target specific muscle groups, improving strength and stability during workouts.
