is fluff and buff primarily for bench work? The criteria for the day is under 30 minutes so I cant imagine you want to pre exaust arms and legs with 2-3 movements and then squat and bench in under 3 minutes. Im gathering this is for extra blood work in chest, back and arms to help with bench for a lot of lifters. Just making sure.
Correct. Naturally, when following a specific 10/20 split that I lay out (which you don’t have to do) I would suggest using it for your secondary upper day/bench day/recovery day, since most of the templates and people who use 10/20 have 2 lower body days just by default. It wouldn’t make sense to have 3 lower body days and only 1 upper body day- being bench day, would it?
