Yesterday Sensei explained his donut theory of martial arts. There is a circle around an individual that describes the arc of their attack. If you’re inside or outside the donut you don’t get the full force. If you’re on the donut, look out.
I nodded and translated this to my mind’s eye, and then we went back to practicing a counter to round-house kick. A few minutes later Sensei looked at me and said “You’re on the donut.”
Damn.
