When an Olympic decathlete tore his hamstring just 17 days before the Games, his medical team faced an impossible timeline. Traditional rehabilitation called for up to four weeks of recovery. He had less than three.
The solution? Blood flow restriction training — a form of targeted compression that allowed him to complete up to six sessions per day, rebuild strength without heavy loading, and reach 95% of his maximum sprint velocity in time to compete. He finished the decathlon. No adverse effects.¹
This isn't an isolated story. It's the reason targeted compression has quietly become one of the most clinically supported rehabilitation tools in professional sports.
What Is Targeted Compression Training?
Targeted compression — also called Blood Flow Restriction (BFR) training — works by applying controlled pressure to the limbs during exercise. This partial restriction of blood flow creates a low-oxygen environment in the muscles that triggers the same growth signals as heavy lifting, at a fraction of the load.
The result: muscle strength and hypertrophy using weights as light as 20–40% of your one-rep max.²
For injured or post-surgical patients who can't tolerate heavy weight, this isn't just convenient — it's a clinical breakthrough.
Why Elite Athletes Use It
NFL teams, NBA franchises, and Olympic programs have integrated BFR into their rehabilitation protocols because the research consistently shows what coaches and physios have known for years: you don't need to load heavy to get strong.
Jadeveon Clowney became the first publicly documented NFL player to use BFR training in 2015 after a lower leg injury. Florida became the first college athletic program to adopt the method, followed by at least 13 NFL and NBA teams within the same year.
The reason is simple. Traditional rehabilitation after surgery or injury carries a significant risk: muscle atrophy. Without the ability to load the muscle, strength declines rapidly — sometimes within days. BFR interrupts that decline.
Research published in the Journal of Sport Rehabilitation found that low-resistance BFR training increased both strength and muscle size compared to traditional high-resistance training in as little as four weeks in Division I collegiate athletes recovering from ACL reconstruction.³
The Science: What's Actually Happening
When targeted compression is applied to the arms or legs during exercise, it restricts venous blood flow out of the muscle while maintaining arterial flow in. This creates metabolic stress and cellular swelling that activates the body's muscle-building pathways — the same pathways triggered by heavy lifting.
According to a peer-reviewed review published in PMC (PMC8811521), BFR training:
- Prevents muscle atrophy following injury or surgery
- Improves muscle strength and hypertrophy with loads of 20–30% of 1RM
- Reduces stress on joints and connective tissue
- Accelerates return to full strength and function²
A companion study (PMC8811501) found that BFR enhances rehabilitation outcomes in both preoperative and postoperative phases, and that the method produces meaningful neuromuscular adaptations even in athletes who cannot perform standard resistance training due to injury.⁴
The results match heavy lifting. The strain doesn't.
From Elite Rehab Rooms to Your Living Room
For decades, targeted compression lived in military hospitals, professional training facilities, and Olympic medical programs. The equipment was large, expensive, and required clinical supervision. The original KAATSU device — the first commercialized BFR system — cost over $16,000.
That's changed.
Suji brings the same clinically validated technology into a compact, app-controlled system anyone can use at home. Smart cuffs auto-calibrate to your limb size, the app guides your sessions, and the pressure cycles are managed automatically — no guesswork, no clinical setting required.
Three 15-minute sessions a week. The same method that got an Olympic athlete back on the track in 17 days.
Who It's For
Targeted compression is particularly valuable for:
People recovering from injury — maintaining muscle while the body heals, preventing the atrophy that makes recovery longer and harder.
Pre-surgical patients — building strength before surgery (prehabilitation) to improve post-operative outcomes and accelerate return to function.
People over 40 — who need effective strength training without heavy joint loading, especially during perimenopause and menopause when muscle loss accelerates.
Busy people — who need short, effective sessions that fit around a real schedule.
The Bottom Line
Pro athletes don't use targeted compression because it's easy. They use it because it works — clinically, measurably, and safely. The research base is deep, the adoption is widespread, and the results speak for themselves.
You don't need to be a professional athlete to train like one.
