PSDTC Workshop Highlights Vol. 1: Grappling for MMA Fighting Workshop

  • Achieve Tight Positions

  • See Effective Striking Utilizing Jeet Kune Do & Filipino Martial Art Methods

  • Learn Effective Use of Tight Position Transitions to Striking with Many Submissions

Filipino martial arts with or without a weapon can be used effectively in any range of combat. See how the flow of positioning while striking in grappling range changes the whole grappling game and makes it much easier to find various submissions. Watch as transitions flow into tight positions while utilizing Filipino striking methods from Jeet Kune Do, Kuntao and Panantukin.

Ron Kosakowski, a practicing martial artist since 1967, began intensive training in Filipino Kuntao under the late Grand Master Joe Rossi in the mid 1970s. He has since trained in many other South East Asian styles such as Kali, Muay Thai and Silat. A certified instructor in Jun Fan Gung Fu/Jeet Kune Do under Sifu/Guro Dan Inosanto, Sifu Larry Hartsell, and Paul Vunak, Ron has trained in many grappling styles such as Brazilian Jiu Jitsu, Russian Sombo, Shoot Wrestling, Judo, Catch Wrestling, Dumog, along with various Silat wrestling methods-all of which are a part of his grappling program.
