The Claim

If you're new to lifting weights, heavy lifting makes you stronger faster than light lifting with blood flow restriction, but both methods build muscle about the same.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

If you're new to lifting weights, heavy lifting makes you stronger faster than light lifting with blood flow restriction, but both methods build muscle about the same.

See the scientific wording

Untrained individuals achieve greater muscle strength gains from high-load resistance training (HL-RT) than from blood flow restriction training (BFR-RT), with an effect size of −0.552 (95% CI: −0.722 to −0.382), while muscle hypertrophy gains are similar between the two methods (ESdiff = −0.128, 95% CI: −0.272 to 0.015).

1 study

  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

    This study found that if you're new to lifting weights, you'll get stronger faster with heavy weights than with the blood-flow-restriction method, but both methods help you build muscle equally well.
