Eddie Bravo is the man credited with bringing "the twister" to MMA and Brazilian Jiu Jitsu from amateur wrestling where it's known as the guillotine. Before Saturday night the hold had been used to end five professional MMA matches, but never a UFC match. Chan Sung Jung changed all that by forcing Leonard Garcia to tap to the painful spine lock in the 2nd round of their UFC Fight Night 24 bout. In the video below, Bravo breaks down the hold as Jung used it and also talks about some alternatives to use against opponents who recognize that the move is coming.
Bravo even manages to work on some wing chun references into the video. He also features his bunnies and his kitty kat and accuses the woman working the camera of blocking the view with her fingers (she's not).
