Bottom Line Up Front: I give this gym 5 out of 5 stars -- and that says a lot because I've been training in martial arts since 1995 and am a certified instructor in multiple systems. But let me break it down as to why it gets my seal of approval. What You'll Learn: Rounders offers multiple martial arts: Boxing, Muay Thai (kickboxing), Brazilian Jiu-Jitsu, Kali (a Filipino knife-fighting system), and Mixed Martial Arts (which combines striking, wrestling, and Jiu-Jitsu). In the past they have also offered wrestling and Judo. So there's something for everyone. Regardless of what class you pick, you'll learn how to protect yourself while getting a great workout. What You'll Gain: Like I mentioned, you'll get a killer workout in a safe and fun environment. According to some studies, you could burn anywhere between 300 to 800 calories in a single 1-hour kickboxing class. It's far more efficient (and fun!) than running on a treadmill. And the added bonus is that you'll learn self-defense along the way. Who You'll Meet: From co-owner Joe Kim to all the other instructors, the coaches here are physically talented, knowledgeable, and easy-going despite being deadly warriors. They create a positive atmosphere so that everyone -- from brand new rookies to combat sports veterans -- has fun while learning. And that trickles down through to the students, who are all supportive and welcoming. The Space: The gym is medium-ish in size compared to other gyms in the area; enough to hold one large group or two smaller sessions at the same time. The equipment is top notch. And the workout space is well maintained. There's also a small section for weight training, too. The Cost: I've visited other gyms with outrageous prices (like $200 a month for only Jiu-Jitsu!). Fortunately, tuition here is reasonably priced -- with options to drop-in, go month-to-month, or commit to 6 months or a full year. (The latter two doesn't mean you have to pay upfront, just that you'll be charged automatically for your chosen time frame and save more over the long term.) And considering those options give you unlimited classes for all of the martial arts classes, Rounders is totally worth it. Conclusion: Rounders MMA Fullerton is an ideal gym to join, whether you're looking to lose weight, learn some self-defense, or just belong to a cool community who will encourage and grow with you. read more

I haven't join many MMA gyms but I am glad this was my first. Everyone is so nice and welcoming which was a big reason for me to keep continuing. The coaches here are the next big reason. They're very accommodating especially since I was a newbie. I love that they offer different styles like boxing, muay thai, and Kali. I've been looking for a good place to learn kali and glad my search is over. The instructor Pat is really knowledgeable and super nice! I only wish there were more early morning classes so I can get a workout and learn before i start work. read more

Rounders is a hidden gem in Fullerton, offering a great variety of martial arts--from kickboxing to BJJ. Joe, the owner, is incredibly kind and welcoming, with an exceptional ability to coach students of all ages and experience levels. I've also had the chance to attend noon BJJ classes with Professor Danny and always leave feeling more skilled and confident. Overall, Rounders provides a safe, supportive, and effective environment to learn and train martial arts. read more

I was looking for a place to begin training again after high school wrestling. I always wanted to learn how to do Muay Thai and this was a great place to learn. The coaches make the classes fun and have the patience to teach new people the basics. I knew nothing when I came in and now I want to compete for the gym! read more

Happy to see how much my boys have progressed after attending for just a few months . After looking around to find where to sign my boys up, I was very pleased with the price point and standard of the classes.

I had an awkward experience sparring when the owner Joe took me out of sparring session for not not knowing too much combos .it really just bought my confidence down and now thinking about quitting. Nonetheless it's really affordable classes and kind generous employees. read more

Been training at this gym for about a year now. All the coaches are great and I have learned so much. The community is also warm and motivating. I look forward to many more years here. read more

We've tried a couple places for our son to start learning new skills in fighting/self defense and Rounders has been the first one my husband and I both absolutely love! Our son has only been in the class for about a month now and has already made some great progress! We're excited to see how far he can get! read more

in my 4th year here at rounders can gladly say that I've loved my time here witnessing my own growth throughout the journey and haven't switched gyms since. it's a great environment with dope people that feels like a family along with dedicated helpful coaches that are highly knowledgeable and will enhance your skills in all areas to the next level. Plan to keep on competing and would definitely recommend if wanting to pursue a new hobby or just for fitness read more

Stopped by this gym a couple of times and I would just like to say that my experience has been wonderful every time. The gym is still fairly new so they do not have a pro team yet but I believe that they have the teaching skills to change that quite soon. The facility is definitely not the biggest I have ever seen but has the capability of hosting two classes at once (jiu jitsu and muay thai/boxing). If I can remember, there are probably around 10 bags ranging from boxing and muay thai variants which is more than enough for a single class. They also have a bunch of thai pads and mitts so no worry for that. The class sizes are fair. I usually went on days where there were 15 or less people so I really liked the amount of time it allows the coaches to help you. There are usually a lot less people in the morning from what I know and sometimes I prefer that. Overall, I believe that this young gym has a lot of potential of being one of the top gyms in Orange County. -Signed Damien Gilbert read more

In love with this new gym! I originally went to the one in Santa Ana first and when I heard about this new place, I had to check it out! Great location and a lot more spacious (also because there aren't as many people as the Santa Ana one yet!). Several different classes that are offered for all ages! They not make sure you get a great workout in but also maintain proper form in the process so you're not injured. Bao is amazing and is always willing to offer his knowledge in any aspect of his field; and if he doesn't know it, he'll help you find the right resources. Definitely check out this new location if you haven't done so already! Amazing customer service and superb facility. You won't regret it! read more

Great class, dropped in few days ago wile on vacay and it was a blast. Bao gym owner have so much knowledge and was ready to jump in roll with us and show us some of his moves. Highly recommended to go check this place out if you are in the area. read more

Highly recommended. They have excellent coaches who focus on good techniques and workout buddies who come consistently and work hard. It gets very busy in the evening but I never have problem joining a class due to it being full. I heard they will soon have shower facilities so that is a big plus. Just two minor things: (due to the many classes and good attendances) the floors and mats needs to be cleaned more often or more thoroughly. Also, some items that are worn out (jump ropes and practice pads) should be replaced promptly. read more

Brand new MMA gym just popped up so I decided to drop in to check it out. Definitely a very nice, spacious place to take up some jiujitsu and kickboxing classes. I have no martial arts background so both of the instructors, Bao (owner I think) and Joe walked me through the steps and details of the gym membership. I was very impressed and found the costs were very reasonable so I decided to sign up. Let me tell you...MMA workouts will kick your @ss!!! Definitely got wonderful instruction from Bao and Joe both who previously fought on the pro circuit. Class sizes were not overcrowded so you get the 1:1 attention. Definitely my new thing and looking forward to my next visits! read more

Rounders is a great place to train. The coaches are experienced and the students are great to work with too. If you're interested in Muay Thai, boxing, or Jui Jitsu I highly recommend this place. read more

This place is a scam. We signed my son up for a one time trial back in late may just to try it out. However things didn't go too well and because my son will soon start behavioral therapy we ended his trial after one month. Just last month, we received 2 automatic payments on Sept 23rd and 30th, each at $133.67. I had emailed them in regards to the repeated charges. And was told that the membership is cancelled and no further charges would be made. However Joe Kim didn't mention anything about refunding us. I later reached out to him on text about the refund and was told that our membership was on a month to month subscription. We don't recall signing up for any subscriptions. Mind you, we weren't charged for the month of June, July, or August, but was charged TWICE in September. We were charged over $200 for services that we didn't receive nor want. Instead of correcting this and making it right to better his business, he rather just take our money. read more

I was curious about this location, since I've passed it a few times and I've been wanting to get into martial arts and boxing, as well as trimming off unwanted weight along the process. I stopped into this location, paid a visit and was very impressed by what they have to offer. Bao helped me get started in the process of joining this gym and has been nothing but excellent & above exceptional service as well as the gym location itself in Fullerton. Not only do they provide training for martial arts, but also MMA, Brazilian Jiu-Jitsu, Muay Thai kickboxing & much more which I hadn't realized until stopping in! Which has me interested in their Jiu-Jitsu program now too! The staff & other clients are very friendly and helpful. It is a judgement free zone and everybody involved is always encouraged and very well accommodated along their journey! Highly recommend this place. Again, Bao thank you so much! read more

Having studied self-defense since 1995, I can say without a doubt that Rounders MMA Fullerton is a top-level martial arts studio for everyone -- kids, fighters, and families. Whether you take their Muay Thai, Boxing, or Brazilian Jiu-Jitsu class (and they offer more than that), you will get a killer workout while also learning how to defend yourself. Sure, Pilates or weightlifting will get you ripped, but neither one will teach you how to fend off a violent robber. Though their gym is relatively new, Coach Joe and Coach Bao offer decades of elite experience with technical teaching skills -- and the best part is that they're such cool and laidback guys. They provide safe learning environment that's intense yet fun. read more
