Summary
Hailey Bieber’s gym selfie showing two tight bands on her thighs sent users searching for Blood Flow Restriction training, a rehab method newly thrust into the social-media spotlight.
BFR works by partially restricting venous blood return while preserving some arterial flow, making muscles respond as if under high-intensity work even with light weights and less joint stress.
A 2022 meta-analysis of 25 studies selected from 327 articles found BFR improved muscle strength, though it did not prove gains in muscle mass or equivalence to heavy-load training.
Physical therapist Noam Klein said the method is most useful after injury or surgery, but pressure must be individually calibrated because improper use can cause pain, bruising, nerve issues or tissue damage.
The technique traces back to Japan in the 1960s, yet Klein said it is unlikely to become a mainstream workout staple because standard strength training remains the core recommendation for most exercisers.
