Smart Cuffs 4.0

Blood flow restriction (BFR) is a training technique that involves applying a specialized cuff or band to partially restrict blood flow to the muscles being exercised. This partial occlusion limits venous return while allowing arterial inflow, creating a hypoxic environment in the muscle. The reduced oxygen supply stimulates muscle growth and strength gains even at low loads, typically 20-30% of one-repetition maximum (1RM). BFR is commonly used in rehabilitation and athletic training to enhance muscle hypertrophy, strength, and endurance while minimizing joint stress. Proper application and monitoring are essential to avoid complications.
