transformed my understanding of kata, karate and self-defence

Even as a Third Dan with long experience of Karate (Shotokan and Goju Ryu), plus Aikido and MMA, it was John’s books that fundamentally transformed my understanding of kata, karate and self-defence. Drilling the book series through, against habitual acts of violence, really gave me the insight to unlock the full genius of the katas; the multiplicity of applications and how to flow them together fluidly and dynamically. After 20+ years, it wasn’t until I put this series of books into practice and drilled them through that I really got it. Each book is about the cost of two karate lessons and I guarantee you that the insights gained in each will impact you much much more.
