For the golfers in your life who want to safely improve strength without strain, this portable, wearable cuff for arms or legs can be slipped on during warm-up or recovery. Beloved by physical therapists and pros alike (namely Justin Rose who counts himself a fan), the app-operated device works by activating key muscles groups through targeted, science-backed compression technology, working smarter, not harder, to relieve stiff joints, reduce pain, increase mobility, and encourage circulation.
