Salutations from Aguirre’s Fighting System PRO MMA & Fitness Gym, the top mixed martial arts training facility in Fontana, CA. Our mission is to bring you ground and stand-up martial arts classes that will push your mind and body further than they have ever been before.


MMA is not just for the macho guys, we welcome all shapes, sizes and most ages. Whether your goal is to get in shape, lose weight, defend yourself, fight off stress or try something new we’ve got a class for you. It doesn’t matter if the most experience you’ve had is wrestling your little brother when you were a kid, or you are looking to expand your study of martial arts, we have the equipment and instructing skills you need to accommodate what you need to grow and learn.


Owner and instructor Franklin Aguirre has over 20 years experience, he has trained multiple pro fighters, and is very confident he’ll be able to train you. It is all about the journey to transformation at Aguirre’s. We hope you walk away from any class with new and improved skills, mindset, techniques and characteristics that will help you build self-confidence, fitness, flexibility, concentration, self-discipline, endurance and any other personal development goals.


At our gym, we offer classes and private session to the public. Our MMA classes include PRO MMAJiu JitsuMuay ThaiCardio KickboxingWrestlingKids ClassesBoxingBoot Camps and Strength & Conditioning.

With our high quality instruction we will create a program that will fit your needs, but at the same time challenges you like you’ve never been challenged before.
