"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."
"Best gym ever! I've tried many boxing gyms in the country and this one is by far the best !! The coaches are great, the facility is outstanding, the vibes are chill. The weight lifting section makes you feel like an NFL player. Everything is clean and it does not smell! 10/10 best gym I have joined !"
"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."
