Now considering how it appears this kid got this strong...
Was he lifting external resistance?
Well other than the curls no. He wasn't.
Is this going to destroy his bones??
Probably not. Why you ask? The way that this muscular system was stressed is in a systemic fashion. He is not doing isolation exercises but rather he is controlling and managing his own body weight. This puts the right kind of stress on bones, ligaments and joints.
Another interesting fact is that the 6-pack you see on this child was not developed by doing hundreds of situps but rather was developed as a result of his body needing stability during the inverted pushups, pullups, gymnastics and other calisthenics.
Reading the comments on this video when it was posted on Yahoo!, there were hundreds of people who were upset claiming this poor kid was ruining his body and developing a "complex."
Perhaps more american kids should "ruin" their bodies like this and develop a "complex" of fitness. Perhaps then we'll stop that runaway train that is childhood obesity. If what you saw in this video disturbs you, then it is definitely a great idea to keep your child away from the following:
- Monkey bars at school
- Jungle Gyms at the park
- Tree's he/she can climb
- Hills they can run up
- Things they can jump off such as benches and steps
- Fun group activities such as partner wheel barrow's, crab walks, bear crawls and other weight bearing fun stuff
Now my disclaimer. If indeed the parents are pushing this boy to do more and to engage in weightlifting at such a young age, then perhaps there is cause for concern. But from what I see. This boy is perfectly healthy and a model for engaging in physical activity instead of parking it in front of his playstation.
