Maintaining
The maintenance dose has been measured: after 16 weeks of training, 32 weeks at 3 sets a week kept muscle and strength.
Bickel 2011 · Spiering 2021 · Androulakis-Korakakis 20206–11 sets
Growing
Each extra weekly set is worth about 0.37 % more growth, and by around 10 sets you already have nearly all the growth on offer.
Schoenfeld, Ogborn & Krieger 201712+ sets
Maxed out
12 to 20 sets per group is the standard recommendation to maximize. Here that bar applies to each muscle. Above it you still gain, but each set pays off less.
Baz-Valle 2022 · Pelland 2025The studies count hard sets, close to failure, and most are of young trained men. FitBook counts the sets you log, without knowing how hard they were: take it as guidance, not a promise. Every week starts from zero on Monday.

you won’t notice it.
