The Filipino Martial Arts (FMA) develop empty hand skills from its weapons training. It is a complete martial art system that has not only weapons, but also empty hand systems, grappling, and forms. The system was originally developed for combat and practical application in relatively short periods of time against other villages or foreign invaders. The training method is systematic and simplistic as only the skills that were proven effective and could be easily taught were used. Training consists of double stick, single stick, stick and dagger, single and double knife, the empty hand as well as a number of traditional Filipino weapons. The CDF program emphasizes training from Marinas Pananandata Arnis (designed for combat or self defense. A great deal of emphasis is placed on stick sparring and knife sparring for the advanced students). The CDF Academy also offers Kali/JKD and Grappling training.
