Over the weekend I attended the Double Impact Jeet Kune Do /Filipino Martial Arts Seminar. On Saturday, Sifu Kevin Seaman gave a master class on applying JKD concepts for boxing, Muay Thai, and self-protection. Then on Sunday, Guro Raffi Derderian gave a master class on advanced Kali and Silat (Indonesian) techniques and principles. An amazing weekend of martial arts was had by all! Great times with great people!
