Suji Smart Compression System A smart compression training system that builds strength without the joint stress. Suji is a wearable compression training system — FDA-registered cuf fs paired with a guided iOS app — that lets you build strength, improve movement, and recover faster using a fraction of the weight traditional resistance training requires. The technology is an advancement of blood flow restriction (BFR) training, with one critical difference: Suji's cuffs auto-calibrate to your individual blood pressure and health data in real time, removing the safety guesswork that makes traditional BFR risky when used incorrectly. The mechanism is targeted compression. During use, Suji's cuffs deliver precisely controlled compression and release cycles to the limb being trained, increasing local muscle activation and blood flow response. The result is that exercises performed at 20–30% of your normal load produce muscle-building stimulus closer to what 70–80% loads typically deliver. For sleepers, weekend athletes, post-surgery patients, anyone with joint pain, or anyone trying to maintain muscle without grinding through heavy weights — the math changes. You get the training stimulus without the joint cost. Three use cases are built into the app: warm up (improve blood flow and prime the muscle before a workout), build strength (low-load resistance training that produces high-load adaptation), and recover faster (post-workout sessions that accelerate clearance and reduce soreness). Available as an Arm Cuff Set, Leg Cuff Set, or both. Compatible with iOS via the Suji app. Basic features free; advanced expert-guided programs available on subscription. Type Cuffs + App Wearable system Cuffs FDA-Registered Targeted compression Calibration Automatic Personalized in real time App iOS Compatible Expert-guided sessions Auto-Calibrated Safety FDA-Registered Cuffs Expert-Designed Sessions USB-C Charging Train Anywhere How Suji Works Three systems doing three different jobs. Suji is more than cuffs — it's a complete training system where each piece has a specific job. The hardware delivers the stimulus, the app personalizes it to you, and the auto-calibration keeps it safe regardless of your starting point. ⊙ Targeted Compression Cuffs FDA-registered wearable cuffs that wrap around the arm or leg and deliver precise pneumatic compression in controlled cycles. The compression activates muscles at lower loads than traditional resistance training requires while protecting the joints from heavy mechanical stress. Designed and built to medical-grade tolerances — not a stretchy BFR band you tighten by feel. FDA-Registered · Precise Pneumatic ⚡ Smart Device + Auto-Calibration A small smart device powers and calibrates every session. It uses your blood pressure and health data from your iPhone to set compression precisely for your body, then adjusts in real time during the session. This is the safety advance over traditional BFR — you don't have to guess the right tightness or worry about over- or under-tensioning the band. The system handles it. Auto-Calibrated · Personalized 📱 Expert-Guided App Sessions The Suji iOS app pairs with the device to deliver expert-designed sessions for three use cases: warm up, strength training, and recovery.
