Blood Flow Restriction Leg Cuff (pair)

The Blood Flow Restriction (BFR) Leg Cuff is a versatile tool designed for recovery and performance enhancement. Made for practicality and comfort, it aids recovery, hypertrophy, endurance, and strength gains (backed by research). With a lightweight and portable design, it can be easily applied and removed in seconds.

Designed by the Founder of Build & Recover, Kyle Wareing MSc ASCC CASES, who has 10+ years working in Elite Sport as a Strength & Conditioning Practitioner, who has prescribed the use BFR on a daily-basis for several years. 

This product is one size fits all, as there are 7 strap points to accommodate for all leg sizes. This product is designed for athletes 16+ who are looking to take their recovery and performance to the next level. 

This product comes as a pair. 

How can BFR aid your recovery? 

Just sit and strap our cuffs around the highest point possible on both legs at a 5-8/10 level of tightness (from your feel). Quick tip - pull the straps to a 10/10 tightness and then work backwards. Strap-in for 5mins and relax, doing absolutely nothing, unstrap completely for 2mins, then repeat the process for a total of 3 times. 

Using a 5-minute occlusion : 2-minute reperfusion × 3 cycles of passive blood flow restriction (BFR)—often called passive strap-in—can aid recovery through several key physiological mechanisms, supported by research:

How It Aids Recovery

1. Metabolic Stress and Hormonal Boost
   Passive BFR creates a hypoxic (low-oxygen) environment in the muscle, leading to metabolite buildup—particularly lactic acid—which stimulates growth hormone and IGF-1 release. These anabolic hormones promote muscle repair, protein synthesis, and overall recovery. 
2. Cellular Swelling (Pump Effect)
   Pressure from the cuff increases fluid within muscle cells (cell swelling), triggering anabolic signaling and reducing muscle damage. 
3. Fast-Twitch Fiber Recruitment Under Low Load
   As fatigue sets in quickly due to restricted blood flow, the body compensates by recruiting fast-twitch muscle fibers—even though no active exercise is performed. This can help maintain neuromuscular readiness. 
4. Enhanced Perceptual and Performance Effects
   Studies involving athletes—such as rugby players—show that passive BFR before high-intensity efforts reduced perceived effort during repeat sprints and helped attenuate performance fatigue, especially in later reps. 
5. Faster Nutrient Flush Upon Reperfusion
   Releasing the cuff (reperfusion) floods the previously restricted muscles with oxygen-rich blood and nutrients, aiding recovery, flush-out of waste products, and enhancing tissue repair.

This systematic review analysed nine studies on passive BFR as a recovery tool. Findings suggest potential benefits for reducing muscle soreness, lowering creatine kinase levels, and improving recovery of performance, although results were inconsistent due to methodological differences between studies.

This review outlines BFR protocols used in rehabilitation, noting that the most common passive approach is 5 minutes of occlusion followed by 3 minutes reperfusion, repeated for 3–4 cycles. It reports evidence for attenuating muscle atrophy, particularly in post-surgical and immobilised patients.

This paper reviews both active and passive BFR applications in rehabilitation and strength conditioning. It highlights that BFR promotes anabolic signalling, improves strength gains with low loads, and can be applied passively to maintain muscle health when exercise is restricted.
