Sumo: A Case Study in Size vs. Technique
November 7, 2016
Sumo is the fusion of honored ritual with unbridled power. Even in a combat sport like sumo, where great body mass and girth are often winning factors, superior technique can overcome size and strength.
Evaluating Drills—Part 2
October 31, 2016
I get especially annoyed with weapons. Unarmed defense against a weapon sucks. Never, ever, ever practice dying and do not train to be killed. The stakes are too high to blindly imprint a habit, even a habit as simple as handing a weapon back once you have disarmed someone.
Evaluating Drills—Part 1
October 24, 2016
I'm not a big fan of most drills. There is a fine line, but conditioned reflexes are crucial in a fight and habits will get you killed. Conditioned reflexes are things you do without thinking about it. They are essentially trained flinch responses. If something suddenly comes at your eyes you WILL do something: block, move your head or, at the very minimum, blink.

This article will discuss several martial arts to illustrate how different looking martial arts are apparently closely related and how the idea of hidden historical roots applies to many martial arts.

DRILL: The One-Step
September 26, 2016
The one-step arose as a useful accident. Many years ago I was reading George Mattson's The Way of Karate and I completely misunderstood his description of ippon kumite.
Not Parlor Tricks - September 12, 2016

DRILL: The One-Step - August 29, 2016
The one-step arose as a useful accident. Many years ago I was reading George Mattson's The Way of Karate and I completely misunderstood his description of ippon kumite. I thought, "That's brilliant—unscripted but safe, just looking at this whole thing as a meat geometry problem…"
Training for Sudden Violence - August 15, 2016
I teach about violence. As I left “the life” I discovered that my niche wasn’t so much teaching cops as I had expected, or even teaching civilian self-defense. The material seemed to resonate most with experienced martial artists who were coming to discover how little they really knew about violence.
Self-Defense: A Unique Teaching Challenge - June 27, 2016
There are six very important distinctions that make self-defense different from almost every other subject we teach. Rarity. Emergencies are extremely rare, complex, and varied. Rarity means there is very limited experience available on how to deal with such an event.
Sai Design and Fighting Theory - January 27, 2016
The correct length and weight of the sai varies from individual to individual. Of course, as with any weapon, the longer and heavier it can be without compromising the handling, the better it is in a combat situation. As the proverb goes, "One inch longer, one inch stronger" (一寸長, 一寸強, Yī cùn cháng, yī cùn qiáng).

If you really want to understand how gloves contribute to the safety of our athletes, especially when it comes to their brains, take a closer look at the physics behind taking a punch with a bare fist or a glove.
Hooks in Violent and Non Violent Encounters - January 12, 2016
