In this short video, we’re seeing decorated Brazilian Jiu-Jitsu champion Bernardo Faria team up with one of the biggest names in heavyweight Judo Satoshi Ishii to give us a tighter kimura variation. Whether it’s new or not, you decide for yourself.

The kimura is a shoulder lock that had been a Judo thing right up until Masahiko Kimura broke Helio Gracie’s arm with it. It has since then been referred to as the Kimura in Brazilian Jiu-Jitsu circles. These people believed in themselves and their combat system so much that they were willing to break or have their arm broken. Just imagine the determination.

Like many other techniques in BJJ it functions primarily through the leverage principle or concept. You’re not using your arms to break an arm. Instead, you frame the arm with a figure four lock. Grab opponent’s wrist. Dive under opponent’s armpit to grab your own wrist. Then you strengthen the frame by bringing your elbows close to your hips and moving your hip and the frame to break the arm. Many people would tell you without thinking that the kimura grip is the strongest grip in BJJ and there are whole systems and instructionals based on just this one grip. You can get it from anywhere: side, back, guard, turtle, dive for it etc.

Mr. Ishii demonstrates a different frame from the one we talked about in the paragraph above. Instead of fixating the wrist with the monkey grip he does so using his forearm in a frame that looks exactly like the genie frame we’d use to defend the armbar. In addition, it will probably turn into a bicep crush kind of submission because you’re really using the forearm to frame it in. Be careful using it. Also, because of the tighter you’ll be maximizing the power of the hip, or rather focusing it.
