Hey, I am a 15 year old male, and I want to lose body fat in the stomach region, and build muscle there and get my arms cut up. My arms are already solid, I just need to get them more defined. Also I have leg problems, and I need workouts for my legs and the stuff listed above. I have tendonitous (sp?) in my right knee, on both of my feet the bottoms of them are always so sore that I can't even walk. I don't know what is wrong with them but I came down hard on one of them in basketball....it sucks, because I have talent in basketball but I cant use it to the full potential.
