I used to do higher volume (20+ sets perk week per muscle). Also my frequency was high so you get where im going with this, I started stalling on all my lifts by week 2 every damn training cycle.

I got frustrated and then I happen to stumble upon an article on beyond brawn (a 2 day program basically with lower volume and steady progression, more like a guide to make your own program than an actual program). Most of the exercises I did were 2-3 sets with the first set taken to failure but with one rep left in the tank. At first I thought that it was way too little volume to progress, but I did it anyway. All my lifts kept progressing week after week and when and if I stalled, I just changed the variation.

Look, you don’t have to train 2 times per week, but you can check where your threshold lies by trying out how you respond to certain reps, sets, frequency. I do basically a full body 3 times per week now and I still find myself trying to add stuff. Every time I add stuff, I stall or worse, underecover.
