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.
The Hidden Roots of Karate and Jujitsu
October 5, 2016
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. First the origins of karate and Okinawan sumo will be explored. Then the root of jujitsu will be uncovered.
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
The following aren't actually tricks. They are exercises that you demonstrate once to show a deeper truth. Most will not work on people a second time. Some will learn to game it.
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.
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.
Defending Against Multiple Assailants Part 2 - July 25, 2016
The axiom that street violence is volatile and unpredictable could not hold truer than when facing multiple assailants.  Facing multiple assailants, let alone multiple armed assailants, is an extremely dangerous proposition.  Try to recognize the situation as soon as possible such as if two people are walking towards you and they suddenly fan out to your left and right.  Running and escaping is your best solution.
Defending Against Multiple Assailants—Part 1 - July 18, 2016
Street violence is volatile and unpredictable.  An attacker will seek every advantage including ambushing you in concert with multiple confederates.  You may well find yourself in a "negative five" position or initially unprepared for the fight of your life.  Krav maga (Hebrew for "contact combat") developed for the Israel Defense Forces will provide you with the instinctive tools and ability to fight for your life and win.
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.
Use of Force and Law Enforcement - May 9, 2016
My opinions on the use of force (UOF) are based on twenty-five years of service with the New Jersey State Police. For ten years I was assigned to the NJSP Training Bureau in roles including lead academy instructor; assistant unit head for the Firearms and Self-Defense Training Unit; use of force instructor; and lead defensive tactics instructor including training recruit, advanced, and in-service members.
Optimizing Force Using Krav Maga - April 12, 2016
A combative strike will have optimum force if you accelerate your strike in combination with correct body mechanics. Principally, this involves a total body weight shift through the target. Physics teaches that acceleration times mass equals force. Your strike will generate more force if you accelerate your speed as you extend your arm and put all of your body weight (mass) behind your strike. This requires proper body positioning and technique.
The Krav Maga Advantage - March 29, 2016
The key is your mind-set: to neutralize an opponent quickly and decisively. In fighting sports, the following tactics are generally banned: eye gouges, throat strikes, head butting, biting, hair pulling, clawing, pinching or twisting of the flesh, striking the spine and the back of the head, striking with the tip of the elbow, small joint manipulation, kidney and liver strikes, clavicle strikes, kneeing or kicking the head of an opponent on the ground, and slamming an opponent to the ground on his head. These are exactly the combined core tactics krav maga emphasizes.
Some Krav Maga Guidelines - February 22, 2016
Footwork and body positioning combined with timing, whether standing or prone, allow you to simultaneously defend and attack, leading to seamless combative transitions essential to retzev or "continuous combat motion."
Krav Maga's Training Philosophy - January 25, 2016
Krav maga is designed around a few core tactics to counter a myriad of attacks. Defenders get tools for their toolboxes along with a general blueprint for how to use them. Imi's goal was survival in any defensible situation. While there are no set solutions for ending an armed confrontation, there are preferred methods using violence of action combined with retzev, or "continuous combat motion."
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.
Hooks in Violent and Non Violent Encounters - January 12, 2016
Dealing with people who routinely used violence to get what they want, they often sought a "hook." A hook is an excuse to act out or a rationalization that will allow them to excuse their actions later.
