Judo: Basics Win Matches
April 22, 2024

With the abundance of martial arts resources and the power of today’s communication technology, YMAA staff writer Gene Ching ponders what effect it might have on the traditional arts for the next generation. 5 Min. Read
The Leg Scissors and Its Descendent: The Triangle
August 1, 2022
So, for the purposes of understanding how the triangle choke has evolved and how it will continue to develop, it’s best to say that it is an offspring with many parents come from many parts of the world.
The Why and Wherefore of Conflict Communication - June 9, 2015
How often have you found yourself in an argument with your wife, husband, or significant other and thought, "Here we go again"? Have you ever found the answer to a real problem and had it ignored while the person you are trying to help wastes time and energy picking at you, trying to create a personal problem from a good thing?
The Players in Self-Defense - February 2, 2015
No matter what levels of force you need, the players stay the same. It is critical to be able to read the players. The threat dictates the situation. You must understand the problem before you can choose a solution. A charm predator is one thing. A drunk wanting to show off for a girl is an entirely different problem. You must learn to read threats and threat dynamics.
Avoiding Workplace Violence - January 26, 2015
According to the National Institute for Occupational Safety and Health, 18,000 people a week are victimized by some sort of workplace violence in the United States. In fact, although industrial accidents abound, homicide is actually the leading cause of death among female workers and the second leading cause of death for men.
The Practical Problem of Teaching Self-Defense - January 19, 2015
Self-defense is unlike anything else humans train for. Unlike engineering or architecture, you can't have any idea of the problem you need to solve. An engineer knows if he will be building a bridge or a tunnel. A self-defense student will never know if they might someday face a rape attempt, a kidnapping, a drive-by shooting, or a simple assault.
I.M.O.P. Principle—Intent, Means, Opportunity and Preclusion - October 6, 2014
How do you know when it is legal to get physical with an adversary? Learn the I.M.O.P. (Intent, Means, Opportunity, and Preclusion) principle. All four of these criteria must be met before you have a good case for taking action. If one or more of these conditions are absent, you are on shaky legal ground.
Never Hit A Girl…Unless She's Armed - September 29, 2014
Sun Tzu and Miyamoto Musashi made no distinctions regarding gender. To them all adversaries were defined as combatants. In today's world, distinctions of gender are made by friends, family, police, and the courts. The role of combatant is, oftentimes, secondary. While experienced bouncers, bodyguards, law enforcement officers, soldiers, jail guards, and martial artists know that women can be just as dangerous, or possibly even more so than men, (such as instinctively going for the eyes during an attack) the courts don't often see it that way.
Modern Trends: Reality-based Martial Arts - September 15, 2014
The rise in recent years of so-called ‘reality’ based martial arts reminds me of other great scams committed against the general public, like bottled water, and who can forget the panic that gripped the world in the 1990s over the Y2K dilemma that was supposedly going to see aeroplanes fall from the sky and shut down every computer on the entire planet.
Account for Adrenaline - September 1, 2014
When I took a defensive handgun course several years ago, I was taught to train for handling the survival-stress reaction commonly associated with actual combat. To simulate the reaction, we had to do as many pushups as we could as fast as we could for one minute.
Common Sources of Knowledge About Violence - March 31, 2014
We are, all of us, both teachers and students. As teachers, we give our students information. As students, we learn from our teachers. The teachers give us knowledge. This knowledge came from somewhere, from one of four sources.
The Victim Interview - February 17, 2014
I was parked alongside a major street in downtown Seattle. My hands were full of boxes and the mid-afternoon sun was glaring in my face, making it hard to see despite my polarized glasses, so it took a couple tries to get my key into the lock. I awkwardly dragged the door open, nearly dropping some of my packages, and began shoving my purchases in to the car.
Teaching Joint Locks - February 3, 2014
About 2003, the training unit at my old agency got some pretty disturbing numbers. Assaults against staff and hospitalizations had increased dramatically. The programs taught at the academy and approved by our agency weren't cutting it. The Training Unit tasked a few of us to redesign the Defensive Tactics program from the ground up.
Principles Common to Both Qin Na and Ground Fighting - September 30, 2013
A lever is the simplest of machines, which utilizes a rigid bar to rotate around a fixed pivot point called a fulcrum in order to exert force on an object (load). If the resistance or load exceeds the strength of the bar, the bar will break. Biomechanically speaking, the arm is a bar, and when the fulcrum is at or above the joint, breakage can easily occur.
Kravist Weapon Defense Drills - September 26, 2013
Working with a good partner to practice and perfect weapon defense techniques is instrumental to your development as a kravist. The force and speed of the mock attacks should be gradually built up over time as your defensive skill sets improve.
Sport versus Combat - May 27, 2013
It was the first time I’d ever made it to the finals. Win and I’d take home the first place trophy; lose and it’d still be a pretty cool piece of hardware. I’d come in third a couple of times, but the little statues weren’t nearly as prestigious as the big ones. And I really, really wanted to earn one of the big ones.
The Ground. The Dirty, Filthy, Dangerous Ground - April 29, 2013
The Raiders fan had biceps that could put Hulk Hogan to shame and a physique that was nothing short of awesome. He stood out in a bar full of average guys, not only because he was ripped, but also because he was the only person cheering for the other team, the only one doing it vociferously anyway.
Karate - A Fighting Art: Use Technology - February 18, 2013
I began training in the martial arts in the summer of 1965. Months earlier, I had broken my lower back in a weightlifting contest and the doctor told me to stop lifting weights and to try something less violent on the body. Therefore, I began karate training.
Lethal Force: Firearms - Part 2 - February 1, 2013
Don’t over-romanticize guns. A handgun  is a nifty machine that throws a hunk of metal in a straight line. No more, no less. A .45 caliber bullet, unless it hits bone and sends fragments spinning, does just as much damage as driving a blunt 45/100 of an inch-diameter stick into the body.
Lethal Force: Firearms - Part 1 - January 28, 2013
While handguns, shotguns, rifles, and carbines can all be used in self-defense, it can be very challenging to justify anything other than a handgun in court, save for in your home (or some places of business) where castle laws might apply.
The Three Golden Rules - December 24, 2012
The three golden rules, first written by Dep. Paul McRedmond of the Multnomah County Sheriff’s Office, must be the basis of all officer training. The fact that they exist, that they are explicitly taught, and that they needed to be stated so clearly says something about the profession.
Level 6-Lethal Force - November 19, 2012
Gary Fadden was a salesman for firearms manufacturer Heckler & Koch. On February 24, 1984, he and his fiancé were driving their Ford pickup along Route 50 in Virginia. This was before cell phones became ubiquitous and he had no communication device inside his vehicle.
