Well... I was able to train all 4days last week after pulling something in my upper right side of my back during deadlifts. I went in yesterday to perform speed pulls and perform 9 doubles before re-aggravating the muscle. I'm thinking it could be my teres major since it's so high up almost right at the armpit. Well... instead of muscling through again, Im taking this week off and then I'll perform active recovery next week. Should be good to 2 go the week after.
