My son is 14 and he is cut up. Has never lifted any weights. Does pull ups on occasion and looks great. It's all from just being an athlete. Plays multiple sports. He doesn't need to lift to look good. I guess its all based upon the kids make-up but I still want them to wait on lifting. No need to rush it.
My son is the exact opposite at 14, not cut up, but beefy and strong. Still some baby fat. Very good swimmer but doing pull ups (not so much).
Did Cross fit and Speed and agility this summer for lax and football. Will try the weight room in a year or so; in the mean time run and do the cross fit training.
