Looks like this is what's needed to win gold ... no need for illicit substances.
This is, in my mind and experience, totally insane, taking into consideration that, in the first video at least, those children must be aorund 5 years old, give or take.
I can imagine the resulting stress on the spine and the ultimate developmental abherrations to the overall musculo-skeletal system(s).
That's besides the other "exercises" ....
The second video is even worse, if that is possible.
In this day and age .... what happened to child protection?
Then again, what happens to those "kids" once they are out of the "games"?
I will refrain from further comment(s) but these videos tell the tale.
