Great coaches who truly care about your progress and a welcoming, supportive community. The atmosphere is positive, motivating, and makes training enjoyable. Highly recommend this gym.
Great group of guys with a team mentality. Class sizes are small, so you get plenty of individual attention. The coaches are highly knowledgeable, and each class builds on the last, so you learn practical chains and combos instead of just random techniques. Coach Jansenn has a ton of experience and a great teaching style. I’ve improved a lot since training here, but like anything, you get what you put in. The environment is supportive and safe. Everyone wants to help you get better, not hurt you. Highly recommend Coach Jansenn’s school if you’re looking to get into the sport.
Thank you Jeev! We'll see you in sparring today!
I have been training in various martial arts for over 30 years, and finding a gym that truly gets it is rare. I joined Underground MMA about four months ago, and I can confidently say this is one of the best training environments I have experienced. The coaching here is on another level. The coaches are patient, technical, and detail oriented, and their ability to break down movement, refine technique and help you understand why something works (or is not working) is exceptional. The training schedule consists of dedicated semi and full contact stand-up, no-gi ground, and MMA classes that bring it all together. The sessions always balance instruction with time to drill or spar (with some sessions fully dedicated to sparring). What truly sets this gym apart is the community. The culture here is all about elevating everyone. There is zero ego and zero pressure. Newer students and experienced fighters all train together with respect and helping each other. The focus is always on controlled, smart training that keeps everyone progressing. The gym is clean, well organized, and run with real pride. And the extras: UFC watch parties, student fight nights, exhibition bouts for friends and family, holiday get togethers, all make it feel like a genuine team and family. The combination of quality coaching, supportive culture, individual attention, affordability, and authentic martial arts spirit that Underground MMA delivers is great. If you’re looking to challenge yourself, learn real technique, build confidence, and train in a safe, respectful environment, this is the gym. Highly, highly recommended. Proud to be training at Underground MMA!
Thank you Mark! Have fun in training today with Coach Jon!
Jannsen is an amazing instructor and his gym is topnotch! He has trained several young men that I know - two were trained throughout their younger years. To this day, they are still really good at MMA. The gym is clean, fun, and friendly. You can work as hard as you want or take breaks. It’s the most supportive place I’ve ever known. And it’s super cool that you can do everything from no contact all the way up to (friendly) sparring, based on your interest level…
I have been training martial arts for about 5 years now with 2 years being at another gym that is more well known throughout the country as a credible gym to improve your martial arts and self defense. That being said the 2 years I was at the former gym I considered were informative however it wasn’t until I met Coach Jannsen Tariga that I TRULY began learning how to correct things I had not received before. Because of this alone and the never ending support of not just Jannsen, but other students and coaches within the gym that everyone is able to feel not only welcome but improve! This is exactly what happened in my story as now I have been with Jannsen for 3 years and I have seen this gym go from a small community to a current actively growing community and more importantly FAMILY ☘️. THIS GYM ENCOURAGES ALL SKILL LEVELS AND AGES! I put this in all caps as needed so people understand that this is yes a gym to improve skill and knowledge in self defense and martial arts, but also so that people understand that this is a SAFE GYM first! We do NOT pressure or force students to spar or do anything they feel comfortable with! This is to ensure one of our mottos that ALL students should be able to train with ANYONE and still be able to GROW, IMPROVE, and CHALLENGE one another without doing what is not COMFORTABLE for them. Would 110% recommend this gym to anyone truly interested in a safe gym to learn martial arts have fun and meet GREAT PEOPLE! AMAZING COMMUNITY!
