Well i have put on 5lbs on in a month at the gym which i'm pleased about. One thing that is bugging me is my biceps. They are getting bigger, but not stronger. I can only achieve what I could at the beginning of Dec 06. On dumbells, I do 10kg 2 x Sets of 10-20 Reps with 1 mins break in between. I can do the first set, then fail at about 12-13th rep on the second set. I there something I am doing wrong? Every two days i go to the gym and I work my arms everytime i go.
