Undisputed Tucson Jiu Jitsu - Boxing - Kickboxing - Fitness Gym

“Couldn’t have had a better experience. Walked into Undisputed with an interest in BJJ and Brandon and Cassie gave me a tour and signed me up for a trial class later that week. I joined immediately after. I’ve now trained at several gyms since moving away and can confidently say this gym is top tier when it comes to their coaches, friendliness, and safety. They take time to get to know their students and are welcoming of all skill levels. Their women’s BJJ program is especially fantastic and I have yet to find anything like it. The gym environment is fun and laid back, but takes training seriously. It’s such an approachable environment for beginners and helped me stay consistent in my training. The opportunity to train with several brown black belts was an invaluable experience. David, Stephen, Yvonne, Tara, Ginny, Gerald, Natalie, Brandon, Cassie, and John were life changing connections and teachers! Thanks for everything, y’all!”

“I am glad found this gym and I love it. I wanted to find a BJJ gym but a friend had invited me to a Muay Thai class so I tagged along. And I have to say the rain I joined was John Bassford the instructor. He really seemed to know what he was teaching, very knowledgeable, and technical. I didn’t realize how knowledgeable he was until my recent trip to Thailand to train at Bangtao Muay Thai. They have many pro fighters coming out of this gym. And I feel like John’s program is very on par with the training in Bangtao. Our group of 15 seemed to perform very well in the Bangtao Muay Thai classes. Very happy John showed us the clinch and the importance of it. Of course I also picked up BJJ. The reason I was looking for a gym in the first place and the instructors are great as well. Stephen and David have really been great to me in helping me compete in local tournaments. I’ve done 5 so far and have gotten nothing but a ton of support here.”

“Fantastic Muay Thai Instructor! I can’t say enough great things about my Muay Thai instructor John Bassford. Their expertise, patience, and passion for the sport truly shine through in every class. Whether you’re a beginner or an experienced fighter, they tailor their instruction to challenge you while ensuring proper technique and safety. The training sessions are always engaging and intense, helping me push my limits while building confidence. They break down techniques clearly, correct mistakes in a constructive way, and genuinely care about their students’ progress. The energy and motivation they bring to every class make learning Muay Thai an exciting and rewarding experience. If you’re looking for an incredible coach who is skilled, encouraging, and dedicated, look no further. Highly recommend! 5/5!”

“This place is awesome. I started coming a few weeks ago. Great instruction and the people here make you feel extremely welcome. Even my 5yr old daughter started kinder jiu jitsu and she loved her first class! I'm excited to see where this journey takes us! I highly recommend this gym.”

“I’ve trained martial arts and played sports since a little kid, I’ve never had a coach like John. His Muay Thai program is authentic Muay Thai, Thailand style. He’s the only coach who has had an impact on my life outside of the gym. Going to Thailand and training with the best of the best was an eye opening experience of how good and authentic the Muay Thai John teaches really is. The programs are essentially identical besides the resources that the Thailand gyms have in comparison to John. Also clinch is Alpha….John is the only striking coach I’ve met that teaches it.”
