if it's in between sets of the big lift for the day it's something low intensity...like chin up iso's...they don't take much out of you....it's a good low trap exercise...and helps keep your scaps locked in place during bench. alot of times on upper body days i'll do all my lower body mobility in between sets just to maintain it. and sometimes i'll do activation between sets...wall slides and scap pushups...or gray cook hip lifts or band side steps. or explosive stuff like box jumps or lateral jumps in between sets of squats or deadlifts.
