I am in excellent health. I go to the gym every day. I am currently 16 and I am on a good diet. I am very fit and I train for tennis. I take a protein bar before and after the gym. I am looking for any information I can take my fitness level to the next game? Should I try and other protein mix or shakes, supplements, suggested workouts, etc... anything you can think of that a typical 16 year old kid might be missing?
