So basically my lower back is sore almost all the time from working out and I'm not sure if it's because I'm injured or just regular working out pain.The pain feels just like a permanent pump/fatigue. For instance, after certain exercises my lower back feels like it's toast: squats deadlifts SLD good mornings bent over rows (i had to stop doing these because it just kills my lower back) It's affecting my workouts because I can't do exercises fully. For instance, if I feel ok on Monday and do squats, all is good. But then if I try to do SLD or bent rows on Weds/Thurs, my lowback gets sore after 1-2 sets because it's already tired from the squatting. The thing is, my lower back is probably my strongest relative body part - so i'm wondering if I somehow injured it? If so, who do I go see about it?
