To Urban or anyone with experience: I'm currently 17 years old, 5'11. training in boxing, and about to start wrestling. I'm very strong for my age and weight, in the weight room. I look like I'm around 150+ pounds, but I only weigh 135 right now. I have 1% body fat. How much should I be weighing right now? I'm eating fast food everyday, but they don't get me fat. When will my body mature and gain weight naturally? I'm thinking about gaining 20 pounds or so to get over my plateau for weight lifting, and also get more knockout power. Any suggestions? thanks in advanced.
