Short excerpt from a YouTube video by Jeffrey Jaime describing use of blood flow restriction (BFR) bands during bodyweight exercises while traveling. The speaker claims that restricting blood flow "fools" muscles into responding as if lifting heavy loads, producing similar hypertrophy/fitness responses while using light weights or bodyweight movements.
Like, I just got back from Park City, Utah, and all I did was work out in my hotel room and the bedroom I was staying in. But I just put on blood flow restriction bands and do a series of squats, push ups, pull ups, et cetera, you know. And the TLDR on that is essentially, you are fooling a muscle into thinking it's lifting a heavy load because you're restricting blood flow to the muscle. And the response to that physiologically is you get the same type of muscle building or fitness response you'd be looking for from using heavy weights, but you can do so with lightweights or with just your own body weight.
