I GREATLY appreciate the new programming re. single leg squat. Deck squats are a serious challenge for me. Over the last few months I've been working on mats and making some very, very s-l-o-w progress. I haven't reached the point of frustration yet, but I could see that point coming.
So putting in those prior motions is really helpful.
If I may be so bold. . . maybe it would be a good idea to put something like that prior to mnpe2 (straddle up). I have the core strength. i cruised through mnpe1. But I totally lack the hip and hamstring flexibility to do a good straddle, let alone a good straddle up. from the forum it appears I'm not the only one with this problem.
I'm working on the middle stretch series, but again I can see it being months - or even years - before I can get past mnpe2. I don't know if I have the patience for that.
