Origin of the Blood Oath
September 18, 2023
And there it was. It’s not only my injuries that wake me in the night. In the vulnerability of the dark, I wonder if the point of Yamashita’s art is not about skill or technique but simply about pursuing an unshakeable willingness to surrender the self in the pursuit of something higher.

Handling Aggressive People
May 31, 2021
Obviously, you cannot simply wish away a possible violent episode to avoid it. Silent hoping has little chance of removing the threat.

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.
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.

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.

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.
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.

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.

Prior to covering krav maga weapon defenses, we need to revisit a few of krav maga’s control holds, two of which are known as cavaliers.

Krav Maga: Defenses Against Hot Weapons - July 9, 2012
