Its a friendly group, the gym is taken care of and I would just recommend it for everyone.

Cannot express how amazing this gym has been for me. Wonderful place welcoming of martial artists of all ages and skill levels! Extremely knowledgeable instructors that will push you to be your best version. Also training partners are great at keeping you safe and learning at a healthy rate. Offering everything from muay thai to jiu jitsu, and even weight lifting classes!! This place is ideal for both people who want to get into shape, or take their skills to the next level. Hit up the owner Joe and he will take great care of you! 10/10

So excited that Rounders now has a Fullerton location. Rounders is an amazing gym with supportive coaches who not only push you to do your best, but also get to know you so that they know what your best is. The people who come to work out are serious about fitness but also know how to have fun. It’s a great place to work out, and it’s so nice to have new and clean equipment and mats. This gym offers a variety of classes so there’s something for everyone.

Great location. Awesome Coaches!

Brand new and convenient location. Great coaches and classmates. I enjoyed my time here and always look forward to coming back. ❤️

So excited that Rounders opened up this location in Fullerton! I get such a good workout and always leave feeling good and accomplished. They offer BJJ, kickboxing, and boxing classes for adults and also kids. Im definitely planning to have my son train here once hes old enough! Coach Joe and coach Bao are super knowledgeable and motivating. Its a big space with brand new equipment and theres also plenty of parking. I also love that its right off the freeway which makes it convenient. I highly recommend!!

Having trained in self-defense since 1995, I can say confidently that Rounders MMA Fullerton is among the best martial arts studios you can find in Southern California. Regardless of what class you attend (Muay Thai, Boxing, Brazilian Jiu-Jitsu, etc.), you will not only get one of the most intense workouts available, but youll also learn how to defend yourself on the streets. Coach Joe and his team of expert instructors provide an elite-level of teaching and, perhaps the best part, are some of the nicest people on the planet. No egos, no meatheads — just a fun, safe, and welcoming atmosphere mixed with killer fitness and fighting drills.

This place, the coaches, trainers, and the members all are awesome and help anytime they can. Have gone to Rounders on and off for 4+ years and the staff and trainers are amazing even with new members that have no experience.

Rounders MMA is a great facility! Coach Bao and his team are the best in OC. I highly recommend everyone to try it out whether you are new or experienced. Great family vibe.

Highly recommend Rounders. The folks here are amazing (almost like a family) and always willing to help you learn. One of my favorite MMA gyms so far.They have kickboxing, jiu jitsu, Muay Thai classes and many more.

Brand new spot, amazing instructors for BJJ,Judo, and Striking.Awesome mat space. Definitely reccomend everyone to try it out.

Good group of teachers and students. I did a drop in with my brother for a no gi BJJ class. There were about 8 or so other people of various levels (some new and some MMA fighters). I have been practicing BJJ for about 12 years and it was my brothers first class. Professor Bao was able to help us BOTH, which is very tough to do considering the difference in skill levels. Will definitely come back and if I lived in the area, I would for sure sign up right away. Oss.

Rounders mma In Fullerton is a great gym with a great vibe and is family friendly for everyone. They have a wide diverse crowd at the gym, from competitors to just your average stay at home mom and the average everyday joe. They offer Brazilian jiu-jitsu, Muay Thai kickboxing, and even boxing. I’ve been training with Bao since he opened up his first gym and he has been such a great mentor to me. He’s teaching at this gym mostly and now I’m training over there also . Make sure you check out this gym if your in the area

This is the best cardio kickbox / mma mixed martial arts / bjj Brazilian jiu jitsu / muay thai gym ever! Classes are super fun for all ages. Perfect for all men women and children at all levels wanting to get into the best shape of their life . I was 177 pounds and now Im down to 159 for the new year! My weightloss isnt a dream and its reality now. Every year i would try to lose 20 pounds and finally with their help i finally got it right and the weight just fell off! The coaches and members are super supportive and welcoming. So glad they have a Fullerton and santa ana location now.

Just visited the Rounders mma and boxing in Fullerton. This location is near the college and a lot easier for me to attend to. Coach bao and joe both coach here and they offer boxing muaythai kickboxjng, bjj, and kids classes here. Definitely stop by and train with these attentive and knowledgeable coaches

Rounders Fullerton is without a doubt the best looking, state of the art MMA gym in town, the instructors there are really knowledgeable and take time to focus on everyone’s individual needs, they offer a variety of classes like Boxing, Kickboxing and Brazilian Jiujitsu. Look into the instructors background, they are well known for their experience in Muay Thai and BJJ. They focus on keeping a friendly environment and you can really tell that Rounders is all about having a zero intimidation zone where everyone will feel comfortable and happy to come to train. Also the facility is brand new and kept clean all the time. Highly recommend to come check this place out.

I train at the location in Fullerton and Santa ana, they offer mixed martial arts classes, Brazilian jujitsu classes, and muay thai kickboxing classes. Its only a small upgrade to train at both gyms and it works out with my schedule training at both locations. Imo best place to train because the coaches really care about your progress and well being. The coaches often will stay after class and often times give me tips and drills to improve. Thanks rounders for helping me lose 15lbs and improving my life
