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.
Kravist Weapon Defense Drills
September 26, 2013
Working with a good partner to practice and perfect weapon defense techniques is instrumental to your development as a kravist. The force and speed of the mock attacks should be gradually built up over time as your defensive skill sets improve.
Sport versus Combat
May 27, 2013
It was the first time I’d ever made it to the finals. Win and I’d take home the first place trophy; lose and it’d still be a pretty cool piece of hardware. I’d come in third a couple of times, but the little statues weren’t nearly as prestigious as the big ones. And I really, really wanted to earn one of the big ones.
The Ground. The Dirty, Filthy, Dangerous Ground
April 29, 2013
The Raiders fan had biceps that could put Hulk Hogan to shame and a physique that was nothing short of awesome. He stood out in a bar full of average guys, not only because he was ripped, but also because he was the only person cheering for the other team, the only one doing it vociferously anyway.
My Experience at The YMAA Retreat Center in Miranda, California Part 2
March 26, 2013

My Experience at The YMAA Retreat Center in Miranda, California Part 1 - March 19, 2013
It was a quiet Monday morning in Bronx, N.Y. at 5 a.m. when I made my usual stop at the deli by the local train to New York City. Out of the corner of my eye, I spotted the former UFC Lightweight Champion, Frankie Edgar, alongside the Bellator Lightweight Champion, Eddie Alvarez, featured on the cover of Black Belt Magazine.
Karate - A Fighting Art: Use Technology - February 18, 2013
I began training in the martial arts in the summer of 1965. Months earlier, I had broken my lower back in a weightlifting contest and the doctor told me to stop lifting weights and to try something less violent on the body. Therefore, I began karate training.
Lethal Force: Firearms - Part 2 - February 1, 2013
Don’t over-romanticize guns. A handgun  is a nifty machine that throws a hunk of metal in a straight line. No more, no less. A .45 caliber bullet, unless it hits bone and sends fragments spinning, does just as much damage as driving a blunt 45/100 of an inch-diameter stick into the body.
Lethal Force: Firearms - Part 1 - January 28, 2013
While handguns, shotguns, rifles, and carbines can all be used in self-defense, it can be very challenging to justify anything other than a handgun in court, save for in your home (or some places of business) where castle laws might apply.
Celebración 30 Años de la YMAA - January 10, 2013
Estoy muy feliz de decir que hoy se celebración 30 años de la YMAA. Desde enseñar a 5-6 alumnos en mi estacionamiento, hacer mi primera visita a Polonia en 1986, hasta ver como YMAA International (YMAA Internacional) crecía país por país y funda YMAA Publication Center (Centro de Publicaciones YMAA), publicando muchos libros, videos y artículos, han sido 30 años lleno de hitos.
