When I was young like 6-10 I was skinny but not real thin, I had a six pack and built, but hardly did any weight training, and now this summer I have been doing some, But havent done a lot, because im trying to do it in moderation for boxing, But my father was Big muscular cut guy, and so were his brothers and sisters, I have a aunt thats built like me and all she does is smoke and drink and never done any physical sport, my grandma was a thick tall lady which is my dads grandmother, and my grandfather was a short broad shoulder muscular guy, They said he could knock bulls out when he was on his farm, so what body type am I, I can gain muscle if I just really wanted to like a body builder, I lose fat really quickly and I have sort of a fast metabolism my legs are very cut and strong, Idk if I have medium size bones I think I do, But am I a ecto-mesomorph, mesomorph, or ectomorph, But when as a kid I was always strong for my size. heres a pic of me after working out today http://i555.photobucket.com/albums/jj470/blah527/h... btw I'm 17
