Blood Flow Restriction (BFR) Training

What is Blood Flow Restriction (BFR) Training?

Training with specialized cuffs or bands that partially restrict venous blood flow from working muscles while maintaining arterial inflow. Allows muscle growth and strength gains at 20-30% of normal training loads, making it ideal for rehabilitation, elderly populations, and injury recovery.

How do you do Blood Flow Restriction (BFR) Training?

1. 1.Obtain proper BFR bands or cuffs (specialized elastic wraps or pneumatic cuffs). Apply to the proximal portion of the limb (upper arm or upper thigh). Tighten to 40-80% of arterial occlusion pressure — roughly a 7/10 perceived tightness. You should still feel a pulse below the band.
2. 2.Select exercises at 20-40% of your 1-rep max. For upper body: bicep curls, tricep extensions, lateral raises. For lower body: leg extensions, leg curls, bodyweight squats, calf raises.
3. 3.Use the standard 30-15-15-15 protocol: 30 reps, rest 30 seconds, 15 reps, rest 30 seconds, 15 reps, rest 30 seconds, 15 reps. Keep bands on between sets (total cuff time under 10-15 minutes per limb).
4. 4.Train with BFR 2-4 times per week. Each session focuses on 2-3 exercises per muscle group. Remove bands immediately after the last set and allow blood to flush back.
5. 5.Can be combined with traditional heavy training: use BFR as a finisher after main heavy sets, or on separate light/recovery days.

How long does it take?

15-25 minutes per session, 2-4x/week.
