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. These are exactly the combined core tactics krav maga emphasizes.

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).
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."

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.

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.

Hand Defenses Against Edged Weapons - August 27, 2012
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
If someone pulls a gun on you and does not shoot, he or she wants something. It is possible that he or she may still shoot you, but not before achieving a desired ends. When possible, compliance with the gunman’s demands is the best solution.
Krav Maga: Leg Defenses Against Edged-Weapon Attacks - June 18, 2012
You will need any and every advantage to defend against a determined assailant using an edged weapon.

Latissimus or Side Lung Breathing or Wing Breath - August 22, 2011
It is not enough to just breathe in and breathe out, or even sigh and linger. You need to develop the skill of moving the air into specific areas within the lungs. Some disciplines call them chambers; some call them sections, and others call them areas, or rooms. I created friendly names and images for the different areas in the lungs—images that will help direct the air or the breath to wherever you desire it to move.
