I can only get 45 on my strong arm, 40 on my weak arm for my 1RM. I am 140 lbs and have 13 inch arms. I am 15 years old (I know I’m gonna get slammed for sucking/being weak). I can do it! I just need 8 weeks or less!

I want 5 solid (no cheating) reps with a pair of 50 pound dumbells. I can do this now with 20s, and can eke out 5 with the 25s but my form suffers.
