hi there.
I havent tried the ladder approach but i dont see how it can work.
Only a marginal intense effort produces growth so what purpose have all the other sub marginal reps? I tried pavels higher volume approach on the PTP programme and felt overtrained and weak all the time even when doing less than half potential reps. My best ever gains came from 1 set of presses, 1 set of deadlifts and 1 set of squats every 9 days-each exercise on a different day and not to failure but very heavy around 5 reps-so i was trying a similar low volume approach with KBs.
