How do i build more muscle on my arms, back, and chest?
Wednesday, February 28th, 2007I’m 13 years old about 5 foot 4 and weigh 115 pounds. my chest is only a 34 inches around. And my biceps are really small too only 10 3/4 inches around when flexed. I want to gain muscle but so far its been really hard because i never seem to have the time with skool and a **** load of homework and all.What could i do that would gradually build muscle that would be easy to do .
