20 years ago in sport BJJ, when you got someone's back, they were done nearly 100% of the time. This was true across all platforms including sport jiu jitsu and MMA. Over the years, I've watched back escapes and defenses get better and better, and more and more people are able to prevent the match-ending choke (the rear naked choke for no-gi, and the RNC plus several more options in the gi). Fast forward to now, and virtually everyone is very good at defending their necks; everyone simply understands that this is the thing to do when someone is on your back. Fortunately for those of us who enjoy the position, the armbar from the back is a very high percentage move that's incredibly hard to prevent if used in conjunction with a choke attack. Here, we'll take a look at a way to use the Kimura grip from the back to set up the finish cleanly and efficiently.
