Hailey Bieber posted a gym mirror selfie in a weighted vest and blood flow restriction bands wrapped around her thighs and below her glutes. After recently calling Pilates “out,” she is now signaling a different lane in celebrity training: lower-load work with a more technical piece of kit.
BFR Bands on Bieber
Molly Gearin said, “BFR bands are placed around an arm or leg and temporarily limit blood flow to that extremity.” She added, “It mimics the effects of heavier resistance training while utilizing only 20 to 40 percent of one’s repetition maximum.”
Louis Chandler, who directs fitness at Alo Wellness Club, said, “I use them with light weights and high reps, usually for accessory exercises or at the end of a workout to get more out of the session without lifting heavy.” He also said, “They’re great for anyone wanting to build muscle with less joint stress, especially if you’re recovering from an injury or looking to add more training volume.”
Gearin And Chandler On Use
Gearin said the bands are used in her physical therapy practice for rehabilitation, and that therapy clinics frequently use them for postoperative patients or those who cannot tolerate heavy resistance. She also said most cuffs have a time limit for how long blood flow can be occluded, which is the practical limit readers should pay attention to before turning a celebrity post into a workout plan.
The broader shift is clear enough without overreading one selfie. The fitness cycle has moved from HIIT toward Pilates and Lagree, and now Bieber is showing the accessory version of that move, with weighted vests still hanging on as a strength-training add-on.
Safety Before Style
Chandler warned that people with circulation issues, vascular disease, a history of blood clots, uncontrolled high blood pressure, or pregnancy should check with a doctor first. Gearin said people with unhealed incisions after surgeries, open wounds, or infections should steer clear of the device.
That leaves Bieber’s post as a trend signal, not a prescription. The useful read for anyone tempted to copy it is simple: BFR is built for lighter loads, but it is not a casual add-on for everyone, and the safest move is to treat the bands like a training tool with rules rather than a fashion piece with a caption.
