The Claim

BFR training doesn't make you stronger at lifting your heaviest weight — it helps with endurance and muscle size, but not with max strength tests like a one-rep max.

BFR training doesn't make you stronger at lifting your heaviest weight — it helps with endurance and muscle size, but not with max strength tests like a one-rep max.

See the scientific wording

Blood flow restriction training (BFR-RT) does not produce superior muscle strength gains compared to high-load resistance training (HL-RT) when assessed using dynamic 1RM tests, indicating that strength gains from BFR-RT may be less specific to high-load movement patterns.

  1. Study: Potential Moderators of the Effects of Blood Flow Restriction Training on Muscle Strength and Hypertrophy: A Meta-analysis Based on a Comparison with High-Load Resistance Training

    The study found that lifting heavy weights gives beginners more strength than BFR training, but it doesn’t say why—so we can’t conclude BFR is worse because it doesn’t mimic heavy lifting.
