I want to gain some visible muscle along my arms what is the best way to do this?

Well you're not gonna notice a huge difference yourself cause you look at your arms everyday and they won't get bigger in a short amount of time, it's a very slow process. Most likely someone else will notice before you that's the case for me. People have told me I've gotten bigger but i couldn't tell how much bigger I've gotten. If you're able to go up on weight then your arms are getting stronger and bigger and you're on the right track it just takes a while to notice results.
