Hi, I'm Mitcheal. I'm 15, and my build is 5'9" 133lbs with 6% body fat. I want to play football but I'm too slender and just not built enough to compete with the other guys at my school. I know if I worked out and put on at least in between 10 and 20 pounds, and improved my overall strength, I could have my pick at any of the starting positions- if all that makes any sense. I'd really like to be quarterback, runningback, or safety. Since I don't currently weight train but I'd like to add the weight as fast as I can, I'd like start out hard, but not hard enough to go over my abilities the first few times in the gym and overwork myself. I'd like to get used to it first and condition myself. Now heres what all you weight training experts and muscleheads have been waiting for: I need my chest, forearms, upper arms, and thigh/calf. I'd also like to know some good supplements to make the workouts worthwhile and help me add the weight. I need more size and weight than strength.
