sounds stupid but I don't really know how to go about getting in shape to get the results i want. to start off i'm 5'8 and aroudn 145 pounds. i'm not fat i'm actually really skinny looking but I have a tiny bit of a pot belly I don't like. also I have skinny ass arms and I upper body so i basically want to lose the little pot bells I have and get bigger arms/ chest so I don't look like a 12 year old boy. i'm not looking to get huge or to be super buff or anythign I just want to get a bit bigger and muscular and have a flatter stomach. so how do I go about this. I was going to join a gym but i have no clue what exercises to do or how often to go or how long i'm suppose to work out for. I also don't really eat junk food and I drink mostly water instead of pop or whatever. should I start eating that protein powder crap when wokring out. I'm pretty confused lol. thanks.
