I would like to introduce you to a fighting principle called the Fluid Shock Wave Principle. I was taught this principle when I became an instructor in a police defensive tactics system called PPCT which stood for Pressure Point Control Tactics.

The Fluid Shock Wave Principle is emphasized in all of the special agent combative system counterstrikes. It is not an unknown concept in the martial arts. This striking principle has been called the focus punch, the energy sink, the heavy hand strike, and many other terms relating to a “vibration” type of strike. Unfortunately, learning how to deliver such a strike often took a lifetime of constant practice, since few individuals understood the strikes physics or dynamics. I will explain them to you in this article.
