"I absolutely love when a submission becomes a position, and that is what Drew Weatherhead has done with the Reverse Kimura. He didn't invent the technique, but his research and training on the subject is unparalleled, as is his instructional breakdowns in this digital course. Having used with this technique for years, I thought I had a pretty decent understanding of it's mechanics and versatility, but this course has shown me layers I never considered. This is the type of game-changing technique innovation that comes along very rarely, which is why it is so valuable and important to pay attention and implement the knowledge from this instructional resource into your arsenal."

"On top of being the premier content creator in the BJJ community, Drew Weatherhead (@because_jitsu) is an outstanding instructor. In this series he delivers an in-depth, detailed, overview of the reverse-kimura system. If you want to get the edge on your opposition, I recommend you check it out!"


"Sometimes simpler techniques (and the reverse kimura is very simple) might get overlooked by more advanced and trendy ones. But the reverse kimura is so solid and easy to use that’s it is well worth everyone adding to their arsenal. At the very least, it offers the user another grip to use when playing closed guard as opposed to the rather predictable collar and sleeve grip. In this instructional Drew pretty much covers all the cool things you can do with it and all the likely reactions you’ll get from your opponent."
