Welcome to our San Diego MMA (Mixed Martial Arts) gym. We’re the leading MMA gym in San Diego, with MMA classes and training designed for Beginners to Pros. If you don’t have experience, don’t worry. We’ll teach you rock solid fundamentals before moving you up the ladder. If you do already have experience, we provide world class training to develop you as far as you want to go.

We work with fighters at all stages of development, but we pride ourselves on building our athletes from the ground up. We’ve had many fighters that started with us as regular students and worked their way up to Amateur MMA Championships and successful Pro careers. And if you don’t want to fight, that’s fine. We’ll still teach you how to defend yourself while getting in great shape.

We teach the most comprehensive MMA classes in San Diego. We’re geared towards beginners who want to learn MMA, as well as experienced fighters looking for advanced training. So if you’re just starting out, don’t be intimidated. Many fighters started here with no experience and we coached them every step of the way. We’ll do the same for you if you have the desire and determination.

Our San Diego MMA classes teach the building blocks of Mixed Martial Arts. Even if you don’t plan to compete, these MMA classes are great for learning to fight while getting into shape. And for those who do plan to compete, we’ll create a specific training plan for you to maximize your progression. Once you’ve mastered the fundamentals, you’ll be invited to Team training. That’s where the fun really begins.

Once you’re ready to start your San Diego MMA training with our team, your development and progress will really take off. Besides continuing to improve your skills in all the other programs we offer, you’ll receive advanced MMA skillsets including specialized Striking and Grappling instruction, while getting to train alongside some amazing athletes.

Our Amateur MMA team is the largest and most successful in San Diego, as well as the rest of California, and we have a young, hungry Pro team. We also host fighters from all over the world who do their training camps with us. So if you’re already a fighter and want to train here, just contact us or come on in.

We provide 4 MMA Coaches for our program, allowing our athletes to benefit from our Coaches’ vast experience and expertise. Chris Leben, a veteran of 22 UFC fights against opponents such as Anderson Silva, specializes in teaching cage work and grappling for MMA. Baret Yoshida, a 2x Jiu Jitsu World Champ, teaches his famous submission style of Jiu Jitsu, as well as Jiu Jitsu defense.

Coaches Vince Salvador and Charles Martinez teach our ambidexterous style of Striking, known for its ability to fight from both sides while using multiple angles of attack. This Striking system is one of the most advanced in the sport and has led many of our fighters to numerous victories.




“I first started training Wrestling here in San Diego and worked my way into striking. Muay Thai and Boxing. Then we had the amateur MMA team tryouts and I went to that. They said “You’re on the team. Keep coming to the team practice.” Then they told me “Hey, you’re ready to fight”. I had my first fight when I was still in high school and just kept moving forward. We have a lot of up and coming Amateur MMA fighters and guys who just started making their Pro MMA debuts. The coaching here is awesome.”



“I’m a fighter in Bellator MMA. Been training MMA here in San Diego with one of my friends from Guam, Vince Salvador. He has a great work ethic, so the chemistry is really good. The kids here, man, they’re turning into men and making a big future for themselves into the sport of Mixed Martial Arts. There’s so many great coaches that are teaching the Kickboxing, Jiu Jitsu, Grappling here. Good coaching staff is what you need and good training partners are another thing too. When you’ve got both like here at The Arena, it all comes together.”
