[Korch]

I just did my A day w/ a starting strength yesterday (squat, bench, dead). I did two sets of deads as my final exercise. A warmup and a heavy set. Afterwards my back feels a bit achy and a little sore. No sharp pains or anything like that and it feels great to stand up straight now (next morning) but i can feel i did deads yesterday. Is this feeling normal/okay or does it suggest some deficiency in my form?
