Title says it all. Here is Ido Portal's take on it: "The standing DOUBLE BACK FLIP, to my knowledge, have never been done before.
Yes, it is performed here on a sprung floor, but because of no use of 'Punching Technique' - the contribution is small to the jump.
Notice the strong use of the arms- not so much for height but for rotation first and foremost.
This achievement stands on the same level as breaking the world 100 meter dash record. Its hard to compare, but on many levels - it may even be more impressive."
This is, simply put, amazing.
