Hmm. You may be correct. I was fairly certain, however, that what we were talking about in camp was a tensing of the outside leg blocking movement at the hips and therefore limiting both CA/CB. If I'm not making sense,
WOW! Did you ever get mixed up? Please be less certain! Does "fairly certain", mean you are not too sure? If that is the case, you are right.
Seriously though, I have never heard this terminology you wrote in any PMTS teaching. Tensing the outside leg to block the movements of the hip? Where does this come from???? Sounds like PSIA! Confusing as hell. That is not PMTS, at least not anything I have ever written.
