Necessity is the Mother of Invention - The Tiger Claw Set
March 18, 2024
The principle behind the Tiger Claw Set is simple: drop your attacker’s primary sensor system at the earliest opportunity before striking other various vulnerable targets until you can escape to safety. 5 Min. Read
Fighting with Weapons
January 28, 2019
Weapons are simply an extension of the fighter. The Samurai even considered the sword to be an extension of their soul. The weapon assumes the character of whoever wields the weapon, as the weapon is simply a tool that extends the will of the fighter. The principles of fighting with empty hands apply to fighting with weapons. A fight is a fight. But there are some thoughts about these principles that should be noted.
The Way of the Warrior
June 18, 2018
In the witching hours of night, after a softball game with friends, police officer Stacey Lim was returning home. As she parked, a vehicle carrying five members of a local gang crept behind her. A young man emerged from the vehicle. He meant to murder her and to steal her car. He wanted to prove himself to fellow gang members. Officer Lim stepped out of her vehicle and turned into the looming barrel of a gun.
Discipline: Keep Cool
May 7, 2018
One of my teachers frequently used the phrase, "Keep a cool tool." Samurai Miyamoto Mushashi expressed this a bit more eloquently centuries earlier, saying, "You must remain calm at all times; in this way you can control the attack."
Winning Fights is Based on Principles—Not Techniques
April 9, 2018
Technique is important. But techniques change, adapt, and evolve. Principles are timeless. Bruce Lee recognized this truth, and advised to “absorb what is useful, discard what is useless and add what is specifically your own.” To Lee, there was no single superior style of fighting. He even referred to his methods as the “style of no style.”
Winning Fights - April 2, 2018
Everyone knows that any fighter can win or lose on any given day. There is even a saying among fighters that there is always someone bigger and better. No one can consistently predict the outcome of two fighters facing each other who possess equal skill. The Navy SEALS have the same problem. Men of all sizes, body types and different skill sets wish to enter SEAL training.
Can We Win the War on Terror? - March 19, 2018
Terrorism and Rapid Mass Murder seem to be permanent, lurking shadows darkening the stage of modern politics. Experts weave a nest of causes, from untempered religious orthodoxy and the moral queasiness of the West to historical grievance and the Internet as a mechanism for radicalization, among others. All, perhaps, carry their measure of truth. I would like to suggest that whatever volatile mix of causes accounts for the menace of terrorism, as a practical matter, the problem is intractable. The prevailing structure of our institutions offers no response to it.
The Spirit of the Warrior - March 12, 2018
The spirit of the warrior touches many across time and place. It is not exclusive to those professionals who devote their lives to it. It touches the mother who, with blinding ferocity, protects a child against danger. It touches the young man who blazes like a flame and charges forward when an armed terrorist storms onto the train that carries him.
Easy Training Equipment for Staff Fun - December 5, 2016
Here is your opportunity to become the "Lord of the Rings" (sorry, I just couldn't help myself!). Training rings allow you to develop accurate, penetrating thrusts as well as circular techniques used in manipulation of an opponent's weapon. They are useful for training both staff and spear.
Combat with the Staff: The Moment of Truth - November 25, 2016
It is not unusual for sparring with the staff to feel awkward at first. There is a big difference between doing drills with a partner, and the chaos of combat against a non-compliant opponent who is trying his best to hit you. Stick with it.
What is Staff Fighting? - October 17, 2016
The staff has been a common weapon among the many cultures of Earth since ancient times. Over the ages, humans have used this basic weapon for self-defense and for contest.
The Art and Science of Staff Fighting - September 19, 2016
The staff, or bo, is one of the most common weapons in the martial arts.  Many karate schools include bo forms in their curriculum. I am here with Master Joe Varady, martial artist and weapons specialist, to talk about the staff.
Brain Damage: Do Football Helmets Help? - September 5, 2016
Recently, the National Football League is facing a 765-million-dollar lawsuit filed on behalf of more than 4,500 former players regarding the concussions and potential chronic traumatic encephalopathy (CTE) sustained during their careers. Similar lawsuits are underway against the National Collegiate Athletic Association as well as the National Hockey League, and football helmet maker Riddell is facing multiple lawsuits over claims about the effectiveness of their helmets at protecting athletes from concussions.
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).
Foam or Knuckles—Navigating the Illusion of Safety - January 18, 2016
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.
Sai: Ancient Marvel of a Weapon - December 7, 2015
Sai (釵, chāi) is perhaps most commonly known in popular culture today as the featured weapon of choice by the comic book characters Raphael of Teenage Mutant Ninja Turtles and Elektra of Marvel Comics. While it is not entirely clear how the sai was created as a weapon, it is widely accepted that the sai originated from mainland Asia several thousand years ago.
Guns, Knives, and the Hollywood Death Sentence - September 21, 2015
In order to become a successful screenwriter in Hollywood, you need to watch a lot of movies, so you can learn from the screenwriters who came before you, and so you can get a feel for what else is out there and popular today.  Unfortunately, this important part of a screenwriter's education is also how Hollywood ends up propagating and recycling incredibly stupid ideas over and over again to the point where the audience just accepts it without question.
Protecting the Brain from Trauma: A Home Experiment to Show We Can Do Better - September 7, 2015
If you put on a football helmet right now and smacked yourself in the head with your hands, you might notice you can hit yourself pretty hard before you start to feel pain. You could even grab a stapler or a coffee mug and hit yourself with that. If you are like me, smacking yourself in the head is the first thing you do when you put a helmet on, just to test it out.
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.
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.

YMAA Publication Center supported the inaugural "Crossing the Pond Martial Expo" held Aug. 14-15 in Seattle, and Aug. 21-22 in Coventry, UK. This expo brought together six well-known and highly-skilled instructors of martial arts and self-defense.
Grandmaster Li, Mao-Ching (李茂清) - March 29, 2010
Grandmaster Li, Mao-Ching (李茂清) was born in Qingdao city (青島市), China, on July 5, 1927. He first began training martial arts in 1934 when he was eight years old, under the instruction and guidance of his father and his cousin Shang, Huan.
Listen to the Subtle (and Not-so-Subtle) Warnings - January 6, 2010
We’ve spent much time writing about awareness on the street. It’s important in relationships too. Don’t turn your brain off when you walk into your home.
Violence: What Everyone Needs to Know About Fighting - August 2, 2009
According to the Bureau of Justice Statistics, men commit about 80 percent of all violent crimes in the United States, serious stuff like homicides, rapes, robberies, and assaults. Men are twice as likely as women to become victims of those same violent crimes, except for rape.
