Ok, so I am built like a bear. I am not skinny, but have run long distances, to include a marathon and 25-plus mile hikes and have done some power-lifting. My son has the same broad frame. He is 75kg at 14 years old. In the gym he lifts more than almost all the Asian adult men here. BUT.....he is not skinny. He is what my dad called me at 13...."husky." Huge shoulders and chest, but also a little bit of width around the mid-section. He can go MMA rounds pretty well, and doesn't get gassed like some of the other guys. He trains MMA and jui-jitsu with adults and beats some of them (he embarrassed a middle-aged guy last month when he tried to throw my son and my son tossed him flat, instead). We also have him in boxing. ...but he jogs like a wounded water-buffalo. When I was 13, I was thick and strong, but chubby. By 14, I was lean and had my gym call me "the world's strongest 14-year old" and I was kick-boxing with adults. At 14 I started running long distances. I need advice. I don't want to shame him. But he often doesn't realize that he eats adult portions. I slapped food out of his hand last week and told him "Enough, already!" At 14 I worked out rigorously and last all the baby fat. But he seems more content. He trains and works hard, but he doesn't have the natural drive that I had to lose it. He works out 5 days a week, resting on Wednesdays and Sundays. But he still has the baby fat. I want it gone before he turns 15 in September. Any advice to help him lose weight? I am waiting for puberty to do its work and bulk him up. He did Arnold Presses tonight with me and tomorrow has a pro coach checking his deadlifts and squats again (he rounds his back when he is tired). I had him look through the book "Starting Strength" as well. Any advice on mentoring my son in "physical culture" and diet.
