Hi, thanks for viewing my topic, i am 15 years old. I have been having this problem for a while now, my biceps and triceps feel weak, i was working out today at my friends gym (first workout) and i was struggling to work out with 2kg (dumbbell), sounds stupid but i really think i have a problem, my muscles just give in after about 4 - 5 reps if im lucky.

any help is appreciated!

thanks :)

P.S ... does anybody else have this problem ??
