You can try dealing with the AD. Good luck on that.
Honestly, I think have a sitdown with the kid and discuss what he was able to do beforehand and where he is at now. If he smarts, he'll get the picture. Otherwise, he's probably fucked. See if he can be responsible for his own training and career.
I take it he was on some machine based bodybuilding split with some cardio machine work?
He's gained 10 pounds. Has his bodyfat changed? It sounds like you inferred he gained 10 pounds of muscle but just checking.
