When I hear a professional martial arts instructor advising their students to be more natural, I cannot help but feel contempt. Could any help be less helpful?
What is the most natural method for safely evading a knife thrust, while simultaneously positioning oneself for an effortless disarm and throw? How does one naturally reverse a guillotine choke? People who know the answer to these questions don’t need an instructor or a class; for the rest of us, more detailed guidance is appropriate.
With that said, I am a strong advocate of “natural breathing” for martial applications, in contrast to the more exotic approaches advanced in some dojos.
