Exclusive Tri-Pressure™ Technology offers three customizable BFR modes: Continuous, Intermittent, and Resting. Bluetooth® connectivity pairs seamlessly with the SmartCuffs® app (iOS & Android).

Frequently Asked Questions

What size should I choose?

Measure the circumference of the limb where you’ll apply the cuff. For arms, measure between your shoulder and bicep. For legs, measure the thigh closest to your hip. If you’re between sizes, choose the larger size for optimal comfort.

What are the three BFR modes?

Continuous BFR inflates during both exercise and rest — ideal for advanced rehab or joint unloading. Intermittent BFR inflates only during exercise — great for beginner rehab or joint de-loading. Resting BFR inflates during rest and deflates during exercise — perfect for easing into BFR or advanced rehab protocols.

Does it connect to an app?

Yes — SmartCuffs® 4.0 pairs via Bluetooth® with the SmartCuffs® app, available on the Apple App Store and Google Play for iOS and Android devices. Smartphone not included.

Is it safe to use at home?

Yes — inflation is automatically capped at 80% LOP, providing a built-in safety limit for effective and secure BFR training at home or in a clinical setting.

Do you offer financing?

Yes! Flexible financing options available at checkout.
