Ninja Shit! That was the first thing that came to mind when I saw the video.
When the video starts, Amir Elzhurkaev and Dmitriy Tomaev seemed to have a nice exchange between the two. Out of nowhere, Elzhurkaev throws a double-touch spinning back kick that lands to Tomaev’s liver, and that was all she wrote.
I’ve seen this technique used in movies, but never in an actual fight. I wonder how many people will be practicing this next week?
