  • My favorite parts of working out at 9Round are the fast and dynamic workouts, amazing and knowledgeable trainers, as well as the healthy, supportive environment in the gym. I am never bored while there, and I always feel 110% better leaving after the workout. The community 9Round fosters is ambitious, kind, and most importantly- supportive. The trainers listen carefully to your needs and goals, and will stand behind you and provide you the resources you need to achieve your goals. This gym is like no other I've ever experienced, it's amazing.

  • I love how hard of a workout you can get in 30 min! Plus I have to modify for my knees and I still can get a killer workout.

  • Being able to come in and get my workout done on my time. I’ve never felt judged...this is huge for me. The trainers push me to go jyst a little further....but will give me alternate moves whe I just can’t do something. It’s a great feeling when you go in and are always greeted by name. Thank you Michelle & team for helping me to get back on track

  • What I love the most about the Bozeman 9Round is how the trainers get to know me and help me reach my fitness goals. I feel like each one has formed a genuine connection with me and really wants to help! Aside from that, the entire 9Round system is great. Repeating moves, in different combinations, has helped me build strength. I can now do full push-ups, which I’ve never been able to do.

  • I really appreciate the patience our trainers have, and how they push me to do things I never imagined I’d be able to do. Every time I leave smiling and can’t wait for the next days workout!

  • Several things: the trainers are superb. They do not judge and are very helpful and encourage you. The intense 30 minute workout is exceptional Last, the no class time concept is a brilliant idea.

    Hello and welcome to 9Round Bozeman. I am the owner and so happy to be a part of 9Round and bringing this amazing fitness concept to our small town. I am very passionate about health and fitness and sharing what I have learned on my journey with others. Being a college volleyball player, sports and training hard have always played huge roles in my life. I will never forget the first day I ever boxed....I was hooked immediately. With over 12 years of training in boxing and kickboxing, I stumbled into a 9Round. I was not sure about a 30 minute workout being enough....I was wrong! I decided almost immediately that I wanted to bring this back to Bozeman. I am lucky to get to do what I love everyday while raising my beautiful children in such a positive environment. Outside of the studio I enjoy spending time with my kids and dogs, hiking, biking, being on the beach and traveling. I hope to get to meet you and show you what we have to offer here.

Looking to expand his knowledge, he quickly made the switch to mixed martial arts and full contact kickboxing with a combined 15 fights between the two. He is also a renowned martial arts coach, being ranked under many prominent instructors around the country. His passion in life is to help others along their road to fitness, having began his journey in an effort to combat obesity himself. He prides himself on his ability to not only bring out the best in his clients, but ensure they have fun while doing it. Outside of 9Round you can find him lifting weights, training in jiu jitsu and muay thai and hiking in the gorgeous Montana mountains.
