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.

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.

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 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."
