I was on island for a long weekend, a training partner who previously trained at O2; reached out to see if I could drop-in on an early morning open mat. I was stoked that I got approved. Everyone was extremely welcoming. The level of Jiu-jitsu was very high and although everyone was going after it, there was no one trying to hurt anyone or any big egos. I'm very thankful, I was allowed to experience this wonderful academy and hope to roll with these guys again the next time I'm on Oahu. read more

The students and instructors at O2 are incredible! They offer a variety of classes and everyone is so friendly and welcoming. I joined about two years ago for kickboxing (PJ, Chris, and Justin are incredible), but really appreciated that the membership allows you to divide up your classes however you like. I ended up taking up jiu jitsu and recently started kali escrima with Ian - my only regret is that I didn't start sooner. Marital arts is such a humbling experience, and walking into a new gym can be so intimidating. O2 is perfect for every experience level from the individual who has only seen action movies to the high level grappler and those who spar regularly. As a whole, they call it the O2 fam and it truly feels like it! The gym is actually owned by Mike and Chris, two brothers, who truly give it a family feel. They, and all the coaches, are amazing at what they do and lead their classes with expertise and a lot of humor. And as another reviewer mentioned, this is definitely somewhere where you have to check your ego at the door because it's a fam and we have to take care of each other. O2 is on the second floor above Goodwill along Kamehameha. There's plenty of parking and the lot entrance is on Hekaha. During the pandemic they kept the gym open and prioritized membership safety with online classes then grappling with dummies and working in pods. They offer times throughout the day and on weekends. The schedule is a little modified because of COVID but definitely check them out! read more

OMG! This place was amazing! Oops! Ok let me start again. The people here are amazing! Very informative and willing to help you to be sure you understand why you have to do what you have to do to protect yourself! Glad that I had a male partner and telling him to grab me like you mean it was great! Ok hurtful but great! Only because you don't know how much pressure your attacker will be having on you! Although the more pressure he gave me was better to know how much I have to get out of it. We all should learn a thing or two about how to defend ourselves. Especially now and how his world is coming to. Thank you YELP for another great event that made me more knowledgeable!! read more

World-class instruction from Relson Gracie 1st generation black belts. While classes offered are jiu jitsu, kickboxing and escrima, self-defense is the core of the academy, Relson's curriculum stresses keeping you and your family safe. Not only are these disciplines fun but it is an unbelievable workout. And unlike many other current modes of exercise, this one is actually practical and could one day save your life. It can be intimidating walking into a jiu jitsu/kickboxing school but everyone at O2 leaves their egos at the door and are there to help each other learn and become better at the art as well as in life. Come down for a free introductory class and see how fun and addictive it is. read more

Very easy to find. Located directly across the Waimalu Shopping Center, right above Goodwill. Parking is limited, especially between the hours of 4-6 p.m. weekdays. The tenants are sticklers about parking, so make sure you park in a place that's not directly in front of another business. Safest place to park is at the ends of the parking lot. O2 Martial Arts Academy offer a variety of classes for all ages including Gracie Jiujitsu, boxing, kickboxing, Kali/Escrima, and wrestling. The facility was recently renovated with a bigger space and new mats and equipment. The facility is always clean and lacks that sweaty, workout smell, WHICH IS GOOD! read more

If you want the self-confidence that comes with knowing that you can take care of yourself and your family, O2 is for you; there is a priority on instruction on practical and tested self-defense techniques. If you're a high level grappler looking for advanced belts to roll with, O2 is for you; multiple purple/brown/black belts in most classes ensure there is no shortage of quality teammates to learn from and with. If you've never played a competitive sport in your life and you only wrestle with your lunch, O2 is for you; everyone there from the instructors to the other students look out for each other and have created a non-intimidating environment that is the perfect entry for someone who just wants to try it out. O2 is not for people with a chip on their shoulder or who just want to see how many guys they can tap, see par (3) above; seriously, it's a family where everyone takes care of each other and if you're a jerk you won't be happy. Other stuff: classes at lunch, evening, and weekends. Kids programs so you can bully-proof your munchkins, clean environment! read more

Thanks to O2MAA and Yelp for coordinating a special self-defence class here. It was highly enjoyable and served a lot of practical lessons everyone should have a basic working knowledge of to get away from potentially dangerous situations. The environment was relaxed and clean while the instructors were very welcoming, friendly and respectful. Mike, Chris and their staff took into consideration the comfort level of everyone there. They offer Jiu-Jitsu, Kali Escrima and Kickboxing classes. Really thinking about signing up to enhance what that basic class taught us. read more

O2MAA has classes that teach the fundamental and technical skills needed for self defense but by far the best part of O2MAA has to be the instructors and fellow teammates. The environment is open and friendly for you to learn at your own pace while learning new techniques. Everyone wants to not only help you but get to know you. This isn't a place to pop in for a workout and leave. You'll gain confidence and genuine friendships while learning martial arts. read more

Excellent jiu-jitsu and a great family environment!

Unfortunately, as expected the truth of this story is being misconstrued by this academy. My husband did indeed pull our daughter away from the training session quietly and we left with out saying a word. One of the parents was concerned and stopped us on our way out and asked us if our daughter was ok as she was tapping multiple times and their student never stopped with one of their instructors watching the whole situation occur. There was nothing that happened that even interrupted the class. The parent told my husband to wait outside and he would get the main instructor. The main instructor and my husband were talking, and nobody was threatened as both are professionals. Neither my husband nor the instructor even got loud with one another. It was a relief that they were talking with one another as they are both have martial arts background and a passion for not only the martial art form but the teaching of the youth as well. Funny how the owner wants to make this into a drama session. The main conversation was that he was unaware of what was going on and he apologized to my daughter and tried to calm her down. Mistakes happen and not every action can be witnessed. We were making him aware that his other instructors were not protecting the students when needed. We understand that. When we witnessed our daughter tapping and nothing being done about it with an instructor watching we had enough. However, as a reputable gym as claimed you are, you need to accept that you cannot see everything occur and accept responsibility, not put blame on the students. You don't attack a child or their skill. That is weak and expected when you are in the wrong. The students are there to learn and to know they are safe. As stated, no one ever told us they were prepping for a tournament or even addressed us before class. Yes, my daughter did hold her own but the moves being used were not a typical sparring session or "rolling" as they call it at martial art academies. We have found a reputable gym that teaches technics, honor, courage and to do the right thing and commitment to the Gracie name and legacy. We know the history of the martial art and know the honor that is behind the name. Just because you may have been given a black belt by a Gracie doesn't mean you carry his honor or his legacy. It is apparent that when the master turned his back that his honor and traditions were not upheld. We wish you all the best and we are just informing the community to do you research and find the best gym for their children. This gym was not it for us and we are advising the community to go elsewhere. Our daughter has found the best gym on the island for her and has excelled once again. read more

When I first started, I was a little nervous being the only teen in the adult class at the time. But after a few classes I got used to it because of the instructors and students. They are friendly, welcoming to everyone, and excellent at teaching. If you want a good workout, try out Grant's classes! read more

Best Martial Arts gym ever. Awesome instructors who have a genuine interest in the martial art. Onzukas and other instructors have a "leave your pride at the door" mentality and they truly care about teaching their students. Many highly skilled and experienced JJ players/fighters always willing to share and teach JJ as well as real world self defense. The atmosphere is very welcoming and friendly. I highly recommend for beginners as well as experienced people. They also offer very good kickboxing, escrima, and kids classes(wrestling or JJ). Been taking JiuJitsu and kickboxing classes for almost 10 years!! read more
