I am guessing these guys win any bar fights without to many problems! – Kudo is meant to be a hard style karate hybrid comp under the Kudo banner (Daido Juku)
Basically a combo of karate and judo but as you can see more emphasis on the striking. Anyway this clip is the Russian guys getting it on.
Interesting to note this is an amateur comp…
