Please …… he is and will be normal, he doesn’t take anything he just works out and eats. That what happends when you work …. your body grows. When he stops he will get more fat. If he keeps working out, he will be slim boy at age of 15-20y. Unless he will go into bodybuilding. Most profesional athlets started at verry young age, this way your bones get stronger, your body more adapted to physical challenges, Bones, muscles more agile. There is no such thing as working out too young, whole history is of children working hard, and i mean HARD becose their parents couldnt or didnt wanted too. There is a difference in working out, and physical torture.
How young can a child begin a strength-training regime? Andrew Farnell, the founder and president of Better Body Expert LLC — a personal training company based in North Brunswick, New Jersey — says almost immediately. “Some children come out of the womb ready to do this,” insists Farnell, who says that between 20 to 25% of his clients are children. It all depends on their kinesthetic sense, which he describes as an “ability to have a mind connection with your muscles.” Some children are born with it, he says, and some can’t lift any amount of weight safely because they lack that kinesthetic sense. “All children develop at different rates,” he says. “It’s not totally unbelievable that there are seven year old kids like Giuliano Stroe who excel at this.”
