whats up guys- the other day was my leg day and I was squating. I put 275 on(thats my max squat. right now) and on my first rep, going down I felt a good pull in the left mid of my back. Its bothered me before when using that specific muscle. Anyways i was on the floor for a bit so im gonna give it a few days to heal up but im not sure exactly what happened. Should I have warmed up with less weight? Used less weight in general? I asked a few friends and they said my back muscles might not be as good as my leg. and I should work back more? Any ideas or anything, im really not sure what to do or what happened. Check out the pic below i circled where i felt the pull.
Thanks
