(Btw, I'm 22, 5'9, 140 lbs)
Went to the gym for the first ever on Sunday and did some heavy lifting. Following the StrongLifts program, I did the bench press and deadlifts. I'm pretty sore all over today, but in particular my lower back is pretty stiff. I think I might have done a few deadlifts with poor form. I was planning on lifting about 3 times a week but if I feel this sore I don't know if I can. Should I cut it down to 2 times per week since I am a beginner?
