I have no idea what this show is really called in English, nor do I have any clue what they're saying during the video, but that's not the point.
If you skip through all of the jibber jabber that will have your brain screaming WTF, you'll see a 6 year old and a 7 year old do some incredibly awesome and hard "tricks."
Some of the things they are doing are moves that olympic gymnasts have to do in their routines! It's absolutely incredible. That little boy has to be the strongest little kid I have ever seen in my life.
Gah... The life of talented little kids. I wish I had been a prodigy of sorts.
