Importance of progressive overload for muscle building:
Muscle hypertrophy requires progressive overload.
It can be implemented in many ways: progressing to heavier weight, increasing rep count or adding time under tension in isometric exercises.
Discussion
which rep cadence are you mostly suggesting for hypertrophy ?
As far as I read in a study it was suggested to do 8-12 reps at 60-80% 1rep max.
Below 60% 1 rep max you should aim for 15+ but not more than 30 or so.
I suggest varying to give your muscles different stimuli. For example compound lifts at 1-4 rep range going heavier each week for a set number of weeks then 8-12 rep range (with rpe 7-8) with less rest between sets for a number of weeks. You can even do isometric holds like squat at 90 degrees and progressively increase seconds/minutes. All three are good for hypertrophy.
I like consistently incorporating heavy lifting (1-4) because it has the added benefit of working fast twitch fibers. To that end warming up with box jumps or other explosive movements is also good.
