Mixed Martial Arts (MMA) is perhaps the most practical and intricate sport-fighting system in the world. Comprised of various martial styles, including kickboxing, wrestling, submission fighting, Judo, and whatever else an MMA teacher wish es to throw into the mix, MMA is definitely the all-in-one package when it comes to fighting methods. In the last decade, Mixed Martial Arts has become the most popular martial arts system in the world. With the advent of the UFC and similar TV shows, MMA schools can be found in almost any city in the U.S. But not all schools offer the high-level and authentic training curriculum that A4 Fitness offers. A4 is one of the oldest and most well-respected MMA schools in Los Angeles, with classes taught by professional fighters and highly skilled martial artists.
