I have a question about this episode Dr. Andy Galpin: How to Build Strength, Muscle Size & Endurance | Huberman Lab Podcast #65 and this Hypertrophy Training What is blood flow restricted training?

Blood flow restricted (BFR) training is a technique where a cuff is applied to a limb to restrict blood flow while performing exercises at low resistance, typically 20-30% of one’s maximum. This method can effectively induce muscle hypertrophy due to the metabolic stress it creates, despite using minimal weight. BFR training is noted for its intensity and potential for promoting hypertrophy with less mechanical load, reducing muscle and joint strain 1 2. Proper equipment is crucial to safely restrict blood flow without risking complications like blood clots 1.
