I thought about this a bit as I watched the team competition and the individual all around.

As young as the chinese gymnasts look, I figured Shawn Johnson also doesn't look anything like 16. But the more I watched the more the differences seemed noticable.

Shawn is only 4 foot 9, but once I become used to her tiny stature I noticed that she is physically quite ripped. Her upper legs and rear end are very muscular. And when she walks you'll notice that her arms kind of hulk out a bit almost like a football player (meaning, she has a lot of muscle in her chest, shoulders, and arms).

All in all, I came to realize she actually has a very mature body, she's just really short. The Chinese girls on the other hand seem to have not the slightest hint of puberty. They're not just short, they're obviously undeveloped.
