How It Works
Strap on & calibrate
Place the SmartCuffs® on your upper arm or thigh and press the button. In just 30 seconds, the cuffs automatically measure your limb occlusion pressure and dial in your ideal restriction level — no guesswork, no manual adjustments.
Train with light weight
Work out at just 20–40% of your normal load. The gentle pressure restricts venous blood flow while flooding your muscles with metabolic stress — building strength and size far faster than conventional training alone.
Recover & repeat
After your session, the cuffs automatically release. You'll experience less soreness, faster muscle repair, and greater gains — in as little as 5–20 minutes per session. Suitable for strength training, rehab, and active recovery.
