Alright, so I'm skinny, and definitely underweight. (Don't hate me for complaining because some people would rather be skinny than fat).
But I'm tryin to gain a little weight, but it all goes to my stomach, I think if I keep trying, I'm gonna be a skinny looking guy with a big belly. What should I do to gain weight a bit, but not all on my belly.

I'm also trying to get stronger (my arms, get them bigger). Any tips?
