So today is back day, and Istarted with two sets of deadlifts. I went up by 5 lbs from last week (to 375), and on the first rep I heard a crack and could only pull 2 more reps on that set (I did 5 last time) and nothing on the next one. Afterwards my lower back hurt and I couldn't do the other lower back lifts in my routine and just did upper shit.
It still hurts to round it. I think I rounded my back some on that first rep.
Is this something I should seriously worry about? It's not searing, terrible pain, just pain as if I just did a lot of heavy lower back stuff. Is there anything I could do to increase recovery (I'm doing legs on friday and would especially like to be better by then)? What are your thoughts?
