I have to say, I'm a bit confused by the recommendations in this thread. The kid says he's currently eating 4500 calories a day, and he's going to add approximately 90 minutes of cardio once a week. Even if he's working very hard, I can't imagine he's burning more than 2000 calories as a result of this, and it's probably more like 1000. Why is it necessary for him to add an extra 10,000 calories a week to compensate for this?
