How Suji works
Wrap. Press start.
Train for 15 minutes.
No gym, no barbell, no guesswork. The whole program is three short sessions a week, the app handles the rest.
Lightweight cuffs strap on in seconds. Suji reads your body and auto-calibrates a safe, personalized pressure. No manual tightening, no risk-it-and-see.
Strength, recovery, or pain relief. Expert-built 15-minute sessions guide every rep. Light loads only: bodyweight, bands, or nothing at all.
Compression makes light work feel heavy to your muscles, so they adapt like you lifted. Clinically shown in as little as a few weeks, with a fraction of the joint load.
The mechanism
Light loads.
Heavy-lift signal.
Targeted compression gently restricts blood flow to the working muscle, just enough that light effort feels like heavy effort to the muscle. Your body responds the way it does to heavy lifting: it builds strength. Your joints never feel the difference.
An advancement of BFR. The blood-flow-restriction method used in sports science for decades, minus the guesswork.
Auto-calibrated, not eyeballed. Unlike $40 BFR straps, Suji measures your limb and sets a safe personal pressure in real time.
Active and passive modes. Train with it for strength, or run compress-and-release cycles for recovery and pain relief.

THE COMPARISON
Suji vs. the alternatives.
BFR straps, massage guns, and traditional training each solve one piece. Suji is the only one built to solve all three. Strength, low joint load, and faster recovery, without the guesswork.

Frequently Asked
Questions
Everything you need to know about our products – craftsmanship, care, and more.
Suji is a smart, portable compression training device that helps you warm up, build strength and recover faster without the need for heavy lifting or joint stress. Backed by expert-guided workouts and auto-calibrated compression, it's a smarter way to exercise and recover so you can play harder.
Suji uses targeted compression, which is an advancement of traditional BFR (blood flow restriction). Unlike standard BFR bands, Suji is safer, smarter, and auto-calibrated for your body, removing the guesswork while enhancing muscle activation and recovery. Paired with our app, Suji offers expert-guided workouts tailored to your goals, making it easy to exercise effectively from anywhere.
Suji’s cuffs gently inflate to deliver precise compression to your limbs, which activates muscles faster and improves blood flow. The device pairs with an app offering guided workouts and real-time calibration based on your body.
Suji is trusted by professional athletes, active adults, golfers, tennis and pickleball players, runners, CrossFit and endurance athletes, military professionals, and healthcare experts. It’s also used by individuals recovering from injury or surgery, or managing joint pain, tendonitis, or overuse injuries common in racket and endurance sports.

Many use Suji’s smart, targeted compression therapy to build strength without joint strain, improve mobility, and speed up recovery. Whether you’re training for performance, rebuilding strength after injury, or staying active as you age, Suji makes it easy to exercise smarter, move better, and recover faster, anytime, anywhere.
Yes. Suji is ideal for strength gains without the joint stress of heavy weights. It simulates the effects of traditional resistance training using science-backed compression protocols.
Yes. Suji is designed with safety at its core. It automatically calibrates to your body and adjusts compression levels in real time, making it safer than traditional BFR bands, which can be risky when used incorrectly.
