Arnis is the national martial art and sport of the Philippines, founded by Remy Presas as a self-defense system that emphasizes injury-free training. Recognized officially in 2009 through Republic Act No. 9850, arnis includes a ranking system similar to karate, with belts denoting proficiency levels from beginner to black belt. The art has origins in indigenous combat techniques and is integral to Filipino culture, focusing on skills such as self-defense, discipline, and agility.
