I've had trouble with this one, and have read various routes others have taken to master this at 60 seconds. There have been moderator criticisms about increasing the rest periods, or altering the incremental changes, for the usual reasons. I think this is actually an important exercise that I would really like to master fully.On a good day I can actually do a legless rope climb without kipping, but not in a proper L-sit; I can tell I am not really strong enough to be consistent or have proper form at this point.
I was unable to progress from 5x36 , to 4x48( week 9) by repeating the entire block 2, multiple times , for a period of some months. I could increase the 5X times by using very small increments of perhaps 4 seconds, rather than in 12 second increments at less rounds ( e g 4x48). In other words, ok at 5x40, but unable to properly complete 4x48. Time under tension here is about equivalent, but I just could not complete 4x48 (or more than 5x40)without increasing the rest period beyond 30 seconds for the lat stretch. I could grease the groove, and do 4 or 5 60"holds spread out through a given day, perhaps 12 hours, or so. I just wasn't making progress doing 5 sets with only a rest of 30 " mobility stretch ; nowhere near 60 " of time under tension per round.
So with regret and frustration I completed all of RC in foundation 2, to PE14, and am returning to PE6. Does anyone have a tweak to the increments that worked for them, other than systematically increasing the rest periods, and then dialing back down those rest times? because that is all I have left. I am also going to try and lose 10 pounds, but I am not really far off ideal weight at this point, 185, 5'10".. It won't hurt, but I am not sure that is the root of the problem.
