I cant belive the father pushed his kid this hard, although with my experience in weight training I have learned that the biggest reason for younger kids to put off training untill there teens is the danger or serious injury, usually because they do not work properly, another reason is that their body has not matured, I would be interested to see what happens when he does mature into and adult and what effects this will have on him.
As for the kid in germany as amazing as it is the fact is he does suffer from a disorder which will cause who knows how many problems as his mucles grow uncontrolably.
