hey everyone, i'm not going to lie to you.. i'm completely new to this site and have no true experience with any sort of weight lifting, but i glanced over some of the stickies so i hope i don't bring up any constantly asked questions. i also hope this is posted in the right place. but anyway, i'm a 19 year old male, about 5'11'' and 125lbs. "little guy" that doesn't really bother me, but i'm looking to put on some weight to fill out. i don't know if this sounds ridiculous, but i was looking to put on maybe twenty pounds? i don't even really know if that sounds reasonable because i know i have a small frame in the first place, but just as a hobby really and health because i don't exercise like i used to. but what is recommended for diet (i've been researching creatine too, i think i may try it)? and what exercises do i need to focus on in the gym? thanks for the help.
