Hey Coach, was just wondering about why you've changed your progressions from tuck>adv tuck>straddle/single leg>full to the way it is now for the variations static holds. Open tuck certainly feels a bit more novel and is closer to a full straddle.
On another note I was able to momentarily hold a supinated grip full back lever for the first time this week after mastering the earlier progressions (up to open tuck). Previously I could only occasionally do it with the easier pronated grip.
