I've been lifting with low volume (up to 3 sets) 6 or 7 times a week, with progressive overload, for over a year with some deloading periods. I've seen notable progress but I think I'm having trouble recovering. So I'm experimenting with keeping volume constant but exercise 3 days a week (so, where I did 3 sets in the past, I now do 6).
My question is, what to measure and for how long to see which method is more effective for me?
I'm tracking everything there's to track (lifted weight, reps, personal weight, fat level with calipers)
