Hey Bud!

Thanks for the well-worded post.

I've written about BFR in the book as you know, and it's well documented as a means of producing muscle growth.

Here are some resources you can use to make a call:

Blood flow restriction pressure recommendations: a tale of two cuffs

"Repeated experimentation was required to determine the optimal position of where to apply pressure in order to reduce blood flow to an active muscle. When too much pressure is applied, the skin may turn pale, and if exercise is continued while too much pressure is being applied, thrombosis may occur. It is quite difficult to reduce blood flow by the appropriate amount in order to achieve beneficial effects. It is important to remember that this technique should not be tried without thorough knowledge of how to correctly apply the KAATSU Training protocol because too much pressure may be deleterious."

Thanks Scott, a lot of great info here. The cuff width was something I was not aware of, but thinking about it makes a LOT of sense. With most of the research showing that going "hardcore" with it really doesn't do anything but make it more painful (or dangerous).

One thing I stumbled onto though while reading. So much of BFR training is <50% 1-RM. A MR is obviously going to be higher than 50% (though technically it could be, if you just wanted to take the last past 4 to failure). From my personal understanding of the reading, BFR training has been done up to 80%. But the research shows that basically you got nothing additional for going heavier (well some research showed a greater increase in strength), and that it may not work as well, since venous outflow is enhanced, which basically limits how effective BFR is.

So really, it seems to make the most sense to either use it exclusively on pump sets, or on MRs where you are using a very light load (which maybe does not make sense at all). I'm not exactly 100% convinced it has merit in a MR. As always you have me thinking Scott. Let me know if my thinking is flawed here. (or if you'd rather not comment, that's fine too)
