Is there like a max number of reps you should get comfortable with before you move to the next level? Lets say I can knock out 3 sets of 20 reps at a certain weight with moderate ease, only then should I increase the weight, or should I do it even if I'm doing 3 sets of ten with a little bit of struggle?
id rather not be one of them nikkas with destroyed rotator cuffs in my 30s
