Undisputed | Green Valley Gym | Jiu Jitsu - Boxing - Kickboxing - Fitness

“Two of my kids have trained at Undisputed South for over a year. Through that time, they have experienced boxing, no Gi, Gi, one-on-one lessons and weekly homeschool classes. They have fought in several Jiu-Jitsu tournaments and have performed exceptionally well. The gym has many options of dates and times for busy families, and the coaches give quality and personalized instruction. The owner, Matt Blank, runs a great local business that is professional, clean, and provides a safe environment for children and adults alike. I highly recommend checking it out for anyone interested in specific training, working out, or self defense. Undisputed South checks all the boxes and is a local gem! Call for a free trial session and find out for yourself everything it has to offer!”

“Undisputed South is an incredible gym! I attended a class while in town for work. The coaches and students were all extremely welcoming and took the time to work with me on techniques since I’m fairly new to Jiu Jitsu. The facilities were clean and spacious. I recommend Undisputed to anyone looking to try BJJ and will definitely be returning whenever I am in town.”

“Very happy with the training my three kids have received here from Coach Matt, his daughter Ziva, Coach Keith and the rest of the staff. They've all gone out of their way to help them at every tournament they've competed in. The gym has recently added free wrestling practice twice a week that I'm happy to have my kids participate in as well.”

“Undisputed Green Valley Gym is an outstanding gym with a top-notch environment. The facility is always clean and well-maintained. The coaching is fantastic—knowledgeable, supportive, and great at working with all skill levels. Whether you’re new to martial arts or have experience, you’ll feel welcomed and challenged in the best way. I highly recommend this gym to anyone in the Green Valley area. It’s also an excellent place for kids to learn Brazilian jiu-jitsu and other self-defense martial arts in a safe and positive atmosphere. Great community, great instruction, and a great place to train!”
