From the reviews
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.
Was in town visiting family and did a drop in muay thai class in the 11am slot with Coach D. Everyone in the gym and the class itself was super welcoming! Coach D gave me good guidance on my boxing defense and was a great coach in general, would 100% recommend his class for Muay Thai whether you’re dropping in or…
just dropped in for a session and the arena exceeded my expectations. the gym looks amazing and has all the equipment you could ever ask for. the receptionist was great and went above and beyond with showing me a great experience. the muay thai coach was great as well and i really had a fun time training here.
I was in town for a week for a work trip and wanted to get some training in. I have experience with other martial arts but am new to BJJ - I was blown away by how welcoming and proficient the folks at The Arena were. The instructor was able to balance a class containing advanced students as well as beginners (like me!
New to kickboxing? Start at THE ARENA | The Boxing, Jiu Jitsu, MMA & Muay Thai Gym in San Diego
THE ARENA | The Boxing, Jiu Jitsu, MMA & Muay Thai Gym in San Diego comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never thrown a punch or a kick, that's exactly who a good beginners class is for. A few things worth knowing before your first week. First, you don't need to be fit or coordinated to start — you get in shape by training, not before it, and coaches scale every drill to you. Second, you won't be thrown into hard sparring — reputable gyms build the basics (stance, footwork, and punches and kicks on pads and bags) first, and any contact eases in gradually under a coach's control. Third, all fitness levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first kickboxing class at THE ARENA | The Boxing, Jiu Jitsu, MMA & Muay Thai Gym in San Diego
Nervous about walking into a kickboxing gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.
