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.

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!

Their intro class has 3-4 kids and two senseis. Their beginner class has way more kids and more senseis to balance the ratio.

After searching the underbelly of Reddit and several places online, all positive arrows pointed to Hawaii Judo Academy.

I absolutely loved the breakdown of instruction during class; I felt the concepts and application were taught very well. They have two floors to their facility and offer jujitsu as well. The schedule is on their website. I highly recommend this training facility! The owner and staff are incredibly welcoming.

Calabrese Combat Academy has been an amazing experience for our whole family. The atmosphere is…read morealways clean, comfortable, and incredibly welcoming -- it truly feels like a second home. Coach Jason, Coach Paul, and Coach Taylor have been outstanding with our three younger sons in the Juniors class. They've shown genuine patience, guidance, and consistency that's made a big difference in our kids' confidence and skill. Over the summer, my partner and I started attending the adult Gi and No-Gi classes, and it's been just as rewarding. Having taken Jiu-Jitsu classes at UFC Gym before, I can honestly say Coach Jason's teaching style stands out -- he breaks down the techniques in a way that just clicks and makes sense. If you're looking for a place to really learn Jiu-Jitsu in a supportive, family-like environment, Calabrese Combat Academy is where you want to be.

I also still remember one of my first sensis Roy Woodward always reminding us to always say Please and thank you which I still do to this day. I also had another sensei Sensei Eric who told me if your basics are good every thing else will be good. At first I thought it was just karate basics but he also ment the basics of life like being sn honest and caring person and being someone who has compassion and is willing to help others something i did when I became a sempai. I still pratice the basics at home but forgot the katas. I would love to go back but I'm out of shape and older now body isn't what it used to be LOL.

Pros: It's spacious, everybody is serious at this gym (no chit chatting/on their phone just sitting at the machine), parking is always readily available, they have a WOMEN'S SECTION (this is a huge plus for me!! Ladies, you'll love this section! No boys allowed!), lots of machines and free weights, music is always bumpin' with good music, lots of disinfecting stations. Although they are not opened 24 hours right now due to COVID, this place is great and I don't have to wait for any machines or weights. I can't wait till the classes open up so I could try it, too. Cons: They need to clean...and I mean clean the dusts on the walls and floors. This is minor and could be resolved quickly but it makes me wonder how often they clean when I see the same dust piles week after week in the same area. The women's restroom smells ALL the time. Not sure if there's a plumbing issue but I gag every time I go into the locker room. There's no WIFI... I was surprised they had no WIFI. Otherwise, great gym!
