"Master Danaher's techniques are always high-level and detailed. This time, too, he teaches the principles of the butterfly guard and various techniques based on those principles. As someone who enjoys playing the butterfly guard, I find this instruction very helpful."
A deep dive into my favourite sweep. Lots of key details on how to make this work better, with a clear strategy on when and how to apply it. What I like best here is when John Danaher works directly with his students and corrects their mistakes in real time, similar to how it would be in a real class or seminar.
a lot of great details about sumi gaeshi
John Danaher's Master The Move: Sumi Gaeshi is the definitive guide to mastering the butterfly sweep. This instructional systemically deconstructs the classic Sumi Gaeshi, turning it into a reliable, high-percentage weapon from the seated guard.
