Fantastic experience: Front dude desks are amazing great service

Fantastic experience: Cool place

Fantastic experience: ⭐️⭐️⭐️⭐️⭐️ This is a great martial arts school!!! So many great trainers here and if you like to try new martial arts you can learn from the best.. Everyone is very friendly and its a great fit for beginners or even if you want to fight competitively

Fantastic experience: I love very intense trading very awesome stuff

Negative experience: Signed up primarily for boxing and Muay Thai. I've been to several boxing 'fundamental' classes at different times of day however they only consist of pad work after a quick warmup with no instruction or guidance (or at the bare minimum we are taught one simple combo that we drill for the entire hour). Otherwise, we are just doing random combinations without actually knowing if your technique is correct, there is 0 feedback or communication from the coaches even if the class is small. The coaches are definitely experienced but they don't seem to care about improving your skill at boxing unless you are on their boxing team. With that said, S&C and Muay Thai were excellent and the coaches were very attentive, I can't speak about the other classes as I haven't been to them. Ken and Dylan at the front desk are very friendly and welcoming, and all of the members are very patient with beginners.

Fantastic experience: The Arena is this spot! The whole vibe here is solid, Amazing staff and Coaches!

Fantastic experience: This place is great! Friendly staff

Fantastic experience: Signed up for Muay Thai along with strength and conditioning. Ken at the front office was really cool, walked me through the whole facility. Coach D was super helpful in the Muy Thai and strength and conditioning class and looking forward to future trainings. Great environment, highly recommended.

Fantastic experience: Arguably the best combat sports Gym in San Diego. Did my fair share of research and checked out multiple gyms. As brutally honest as I can be nothing comes close to the schedule, instruction, and passion at The Arena

Fantastic experience: Today was my first day and I absolutely enjoyed it I was going to join a few months back but then I got cold feet but there was nothing for me to worry about everybody was kind and professional

Fantastic experience: Best place to improve your athletic and combat performance. Has everything you need to be the best version of yourself. Staff makes you feel like family. Best Gym.

Fantastic experience: Just started boxing here. Never in my life have I trained. But this is the most fun yet super intense training. I’m happy to show up to class and not know what we will be doing that day. But since coming my punches have gotten better. Just got to practice in this foot work. Definitely recommend, staff is great and everyone is super nice. Like a big happy family.

Fantastic experience: Super awesome place, helpful staff and instructors

Fantastic experience: Good gym. Has classes all day. I love it!

Fantastic experience: I'm a first timer and thisnwas great. Good exercise, great coaches. Highly recommended!

Fantastic experience: Came to The Arena while on vacation; having experience from my own gym I didn’t know what to expect. However, the experience was pleasant and inviting to those of all skill levels and backgrounds.

Fantastic experience: Great place to get a workout in, hit the pads, make friends and encouraged to push through the pain of getting stronger

Fantastic experience: Top quality gym def recommend

Fantastic experience: Excellent gym. Was there traveling from the east coast and they were incredibly accommodating for visitors. Front desk was super friendly set me up with loaner equipment for a couple days. Massive facility, all day classes, and welcoming atmosphere with some serious talent. Stop by if your visiting from out of town.

Fantastic experience: Dylan is helpful and chill

Positive experience: Enjoyed training jiujitsu here for the past year, Adam is an awesome coach. That being said, this gym has a terrible cancellation process. I understand it is 3rd party, but it seems we could do better than paper mailing a letter in 2025 as none of my previous gyms have ever had me do anything like this. Attached is the instructions

Fantastic experience: Everyone was so friendly and professional!! Will come again (:

Fantastic experience: Dillion at the front desk was extremely helpful and welcoming. They answered all my questions patiently, and made the check-in process quick and easy. It really made a great first impression—professional and friendly service all around.

Fantastic experience: Great gym, incredible instructors without all the over the top "yes sir" bs. The community is very welcoming to new people and will make sure you are learning

Fantastic experience: The arena is an awesome place to train Muay Thai! They have a skilled attentive staff who are always willing to help you progress. They are an old school gym and they push you past your limits. Great environment and great people.

Fantastic experience: Love this gym, has great coaches and everyone wants to learn to be the best.

Fantastic experience: Great gym with friendly staff. I mainly do nogi BJJ; mats are always clean and they have plenty of tape, wipes, etc at the desk. Adam is a great coach, attentive to help others and speaks clearly and concisely during instruction.

Fantastic experience: This, gym has always call me out and gave me attention. I could say that they took Me in when I’m on my lowest, and hopefully I could get to be somewhere And be someone because of this gym. It’s going to help Me to get there and heal myself. The coaches around this gym Are the best Especially Coach Steve

Fantastic experience: New to town wanted to try and take up Jiu Jitsu. I signed up online for a free class and showed up. The coach was phenomenal and understanding on my lack of experience. Great environment overall.

Fantastic experience: Love this place, coach D is great!

Fantastic experience: Great and full facility! Super welcoming and easy to work with to help with my fitness and safety goals

Fantastic experience: I really have been enjoying the coaching from Adam for jiu jitsu and I really like the friendly gym culture

Fantastic experience: Arena is really good gym. Staff is very helpful.

Fantastic experience: Great coaching and helpful stuff. Lots of spaced love the gym

Negative experience: Very poor experience as a prospective customer. False advertising, management and owner are total douchebags- details below. I signed up for their trial online that is advertised as 30 days free. I showed up on the first day and took a muay thai class, which I really enjoyed. The instructor was awesome, the curriculum was great, I liked the other students, and the facilities were nice. That night when I got home, I was so excited that I went online and ordered boxing gloves overnight shipped to my door, as well as jiujitsu rashguards and shorts. The very next day my gloves showed up and I was ready for my second class. I gathered my stuff, suited up in workout attire, and headed out the door excited to get another workout in at the Arena. When I showed up at the Arena however, the guy at the front dropped on me that I couldnt work out today unless I signed up for a 1 or 2 year commitment on the spot. This took me by complete surprise and I just wasn't in a position to make that decision on the spot. I explained that I fully intended to be a customer but I needed another day or two to think it over and would really appreciate if I could still do that day's workout. They had absolutely no flexibility whatsoever and I had to go home disappointed. This was a really poor experience as a customer. I would have almost certainly signed up with them but based on this experience, I'm definitely taking my business elsewhere.

Fantastic experience: Most impressive and expansive facilities I have seen yet. Open all day with classes every hour, The Arena features separate buildings for Jujitsu, Boxing and Muay Thai / MMA all connected on one central campus. The staff are welcoming and the coaches are knowledgeable. They have even trained Navy SEALs. Try for one day - 24 hr pass. This place is a gem - a treasure for anyone who lives in San Diego and is looking to develop themselves as a fighter or just to learn new skills and better themselves.

Fantastic experience: Absolutely amazing crew and teaching

Fantastic experience: Very friendly people, learned very fast

Fantastic experience: Pretty epic front desk dude in the afternoon

Fantastic experience: Quality

Negative experience: Great service, great Coaches, a lot of different trainings to choose from and nice people to train with. But at the price of 165$ a month (in 2025) very costly. I personally was completely scammed by their financing company after the guy at the desk told me my subscription was monthly cancellable, it was not. And in the end after I told him I would like to cancel it, he told me he would handle it and I'm all done. Well, my subscription wasn't cancelled, I was lied to and now had to pay multiple months extra.

Fantastic experience: They’re nice to beginners

Positive experience: Great gym atmosphere & quality facility to train Muay Thai, easily the best coaches I’ve had. There are also a lot of amenities that come along with the membership. I must admit the cancellation process is terrible but Ken at the front desk was able to help me through it. I seriously encourage the owners to try & find an alternative to the current membership system, since it does feel kind of sketchy. Nonetheless Dylan was super helpful when I signed up & I don’t regret it!

Fantastic experience: Great gym I would recommend to a friend

Fantastic experience: The Arena is hands down one of the best martial arts gyms in San Diego. The coaches are legit, experienced, and really care about helping you grow—whether you’re a beginner or training to fight. The vibe is welcoming, the facility is clean and spacious, and there’s a strong sense of community. You can train in everything from boxing and BJJ to Muay Thai and MMA, all under one roof. Highly recommend if you’re serious about leveling up.

Fantastic experience: Really good rolls, great atmosphere, and great coaches.

Fantastic experience: Great place to learn.

Fantastic experience: I’ve trained at several different gyms, but nothing compares to the professionalism and dedication of the staff at The Arena. Every morning when I walk through the doors, I’m greeted by a welcoming atmosphere, a clean facility, and coaches whose experience and expertise are truly top-notch. Whether you’re chasing the same dream as others or forging your own unique path, this space brings people together with one shared purpose: growth. It’s the perfect place to start fresh, push your limits, and become the version of yourself you’ve always envisioned—physically, mentally, and beyond.

Fantastic experience: Me encanta este lugar, primero la atención es muy buena, desde la recepción hasta los entrenadores. Nunca me presionaron por pagar mi membresía, me dieron clase gratis de prueba y lo que más me gustó es que es un gym donde realmente se entrena para formar peleadores. Las instalaciones muy grandes y limpias. Lo recomiendo 100% antes de inscribirme a este gym fui como a 7 lugares diferentes en San Diego y este fue el mejor que pude encontrar.

Fantastic experience: This gym is absolutely awesome! One stop shop for everything mma related. One membership you can attend as many classes as you like from jujitsu to boxing and more. The coaches are world class and make it easy for newbies to pick up the sports. I’ve mostly trained under Adam Bradley and Andres Montez and they have helped me love this sport. I also love the fact they have a whole separate strength and conditioning section. Coach D is awesome and very knowledgeable. Overall can’t say enough great things about this gym!

Fantastic experience: I recently started training at the arena and so far it’s been a super cool experience everyone is friendly and the coaches ass well super laid back guys , I highly recommend this gym you will not regret it

Positive experience: I enjoyed the all-women's jiu jitsu grappling class. The instructor, Rose, was knowledgeable and patient. I appreciate that she broke down the techniques into individual moves, which made it easier to follow. My only frustration is that pricing isn't available on the website and that the plans are all-inclusive, so there aren't any options for drop-in classes.

Fantastic experience: This place is a number one mma gym in America. Usually in other places you might pay up to $300 a month just for one discipline like jiu jitsu or boxing and if you want to practice more than one fighting skill then you have to go and pay again another $150-300. This place is super cheap, with a long history since 1949. They have muay-thai, kickboxing, jiu jitsu, judo etc, you name it. and you can practice them all if you wish whenever you wish if you have a membership. They also have a big gym with dumbbells and barbells in another building next to the building where you train. Staff is super friendly and understanding.
