Yesterday I did the chest-shoulder-tricep premix from 4 Day Split. I felt like I was working really hard, although the order of the exercises had me stumbling around and pausing here and there to get my equipment set up. Today I have no DOMS - it feels like I didn't do anything yesterday! I always have DOMS the day after weights. Does this mean I didn't work hard enough? Or is it not necessary to feel DOMS for muscle tear-and-repair to have happened? Thanks!
