Karate is For the Rest of Us - September 20, 2021
There is a public perception of adults who practice karate, borne no doubt of the movies our local multiplex presents us. America's favorite entertainment medium is the province of young athletic people who, in their quest to make right through might, produce skilled strikes that land accurately, rendering perfect unconsciousness in every opponent, and enable our hero to emerge uninjured after battling many wrongdoers. We in the practice know better.

The purpose of a successful throwing technique in sambo is to get an opponent to the mat or ground as effectively as possible with control.

The Three Building Blocks Of Learning And Training In Judo - April 1, 2019
In any field of study, there has to be some kind of structure so that the contents of that particular area of study can be logically understood, taught and learned, and ultimately passed on to others. This structure or framework must have a firm theoretical and philosophical foundation based on practical application and, just an important, allow for innovation to take place. It must be fixed, yet flexible so that the activity (in this case judo) has room to grow.
How Biomechanical Principles Apply to Judo - March 11, 2019

Judo Isn't Gentle - February 18, 2019
Is judo really the "gentle way?" In the popular meaning of the word, judo certainly isn't anything close to being gentle.

And while judo isn't gentle in the more common use of the word, it's certainly efficient; and because it's efficient, it's effective
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.

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.

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.
