i generally do a split routine 3 days. just fits my schedule best.
it comes out to 3-4 workouts per week, that is all i want/need at this point in my life (i'm getting beat up and old)
each split session is around 20 sets. my workouts aren't easy whatsoever but i stopped going super heavy a few years back
if i could go back in time i would tell myself 10 years ago to not lift so damn heavy!
