pick up a couple of muscle mags and read. a good diet is as important as gym time. why you just lifting upper body......you really want to grow......you got to squat and dead lift. stick with a good clean diet and gym time 3 to 4 days a week and get some cardio in on your off days. working out is my favorite hobby, i even get to workout while i am on the job! good luck to you and stick with it.
