Summary

What if the secret to bigger gains is doing LESS work? In this episode of the Align Podcast, Aaron is joined by Alex Birks and Ethan Hill for a conversation on blood flow restriction (BFR) training and why it's gaining traction across rehab, fitness, and performance. They break down how BFR works, when to use it, what to avoid, and the technology that is helping make it more accessible.

0:00.0	Alex Berks and Ethan Hill. Thank you guys for making time to do this. So I spent a good part of last
0:08.9	year doing the rehab and training for Aaron Rogers during his Achilles injury. He ended up having
0:15.5	one of the most kind of like monumental recoveries. I think maybe you could say like in the history of Achilles injuries at least.
0:24.1	And one of the things that we used every day, regularly, multiple times a day in different
0:29.3	situations ranging from if he's just sitting on the couch to training was blood flow
0:34.8	restriction training.
0:36.7	You guys are both experts on this specific topic.
0:41.9	The intention of this podcast is to break down what that is
0:45.7	and how we can get value from that as a general pop human being.
0:51.5	What is blood flow restriction training and why is it so interesting to start?
0:57.0	Either of you.
0:59.0	The idea of blood flow restriction is we're applying some type of occlusive stimulus such that we can apply this device to a pressure which restricts venous outflow from leaving the muscle
1:15.6	when we're exercising. And so you can think of this kind of like a specialized pneumatic cuff,
1:21.6	a smaller, more maybe dainty version of a traditional blood pressure cuff that can be used in sports rehab, can be used
1:29.5	in research settings or in clinical settings or in even in general population, where we apply this device
1:35.8	to a pressure, which we determine, to be adequate to stop venous blood from leaving the muscle
1:43.2	at rest while avoiding affecting arterial inflow.
1:48.6	That is, the pressure is sufficient to stop venous outflow, but arterial inflow is relatively
1:54.4	unaffected. And traditionally, when we apply this device,
2:01.0	we use a pressure that is in the ballpark of 40%
2:04.7	to 80% of what we would call arterial occlusion pressure.
2:11.2	That is, before we start any exercise or rehab
