I'm in sixth grade going into seventh. I hate eating celery and other crap. I eat big portions and i'm 5'9". I weigh 171 lbs. right now and i have the build of my dad. (broad shoulders and huge gut) I also want to be very muscular because i am starting football in the fall. Im also wanting to start this new body of mine for girls. my brother is very tall, skinnny, muscular and fast. i want to be like him but im the complete opposite. im slow, fat, weak, and im a couch potato. so, what stuff can i do?
