I am starting football in a couple months and I really need to put on some pounds because I really want to play linebacker. I exercise a lot, and I think that I basically just can't take in enough calories to make any difference. I weight train 5 days a week and run 4 times. And I drink about a gallon of water a day. I eat as much as I can, which isn't a lot, but I haven't put on any weight in about 4 months. Does anyone have any diets or weight lifting regimins that can help?
