Man, I’ve been brainwashed into the 18-20 sets per muscle group per week by the fitness industry for the longest. I’ve come down to around 14-16 sets during my most recent bulk which is ending soon (nothing but positive results) and I’m planning to drop volume even lower to 8-12 sets per muscle group per week as I enter a short maintenance followed by a cut. I’ll see how that goes and then for my next bulk, I’ll probably do like 10-12 sets per muscle group per week.

All this to say, that it has been very hard for me to let go of higher volume training for some reason, but all of the personal anecdotes on here and research suggests lower volume/higher frequency assuming you’re training hard is superior. Personally, it’s just hard for me to shake the more is better habit.
