Are you still progressing Mike?
If so, why stop?
20 reppers are much, much harder than PPP, if you do them right and not softcockit
Do some BB for a week or two, use exercises you havent for the past 11 weeks, incline press, incline curls, tricep pressdown etc, just dont use that word, it has negative meaning to me
Deload - I've done pretty good for a few weeks, I think I deserve to drop the weight and reps as a reward, train like I used to when I didnt make any progress.
If your putting 400kg on your back every week or pulling 350kg every week, you dont need my permission for ANYTHING, in fact no one does.
I just offer my opinions and what I do with my clients
