 I have trained in countless gyms across the country, that includes Weight Lifting gyms, Boxing Gyms, Mixed Martial Arts, boot camp training and Aerobics. MMA Underground brings all those to the table and is the place I call Home. Wide range of equipment that you can not find anywhere else. Great trainers that will teach and motivate you. If your trying to loose weight, or learn how to fight, or gain some muscle, or just get back in shape, Underground is the gym for you.  

 A great place to train with a great Sensei who loves to teach.
 

Oscar will teach you if you are willing to learn not only Martial Arts but also how the live to Warrior Lifestyle.
 

As someone who is a little older (47) with no martial arts experience I was a little intimated walking in. Oscar put me right as ease. He cares about his fighters. Your training partners in many ways become family.
 

If you are just looking for a great workout he has that everyday also 

I've tried several gyms and could never find a place that I felt like I could fit in or be comfortable or get motivated to achieve what I wanted. MMA Underground is hands down the best experience I've ever had in a gym. Oscar is a wonderful instructor with an extensive martial arts background. The environment he fosters within MMA Underground makes everyone feel welcome and important. They offer several different classes, all which are excellent workouts. Whether you want to compete, become a professional fighter, tone up, or just pick up a new hobby Oscar and the team at MMA Underground can help you achieve your fitness goals. There is even a kids class for young ones to learn mixed martial arts, I have a 7 year old daughter and she absolutely loves it just as much as I do. This gym is positively AMAZING!

I have taken classes at MMA Underground over the past 6 years and love it! I have never had better results from any other workout before-- the 30 minute strength training (Kettlebells, circuits, kick boxing, etc) is always a challenge. Oscar, the owner/instructor, is always coming up with new ideas to keep the workouts fresh, fun, and tough!
 

This gym is for everyone -- whether you are just looking for a good workout or fighter training of all levels. I started with no experience and always felt welcome & encouraged to improve/get stronger. MMA Underground is an excellent value, a great atmosphere, and I would recommend it to anyone (and have)

I don't personally get to train at MMA underground because I live over an hour away however my brother trains there. I couldn't be happier with MMA underground I have seen such a positive transformation not only physically but emotionally in my brother. MMA underground is made up of some of the best people I know. Sensei Oscar is one of the most genuine caring guys you could ever meet. He will give you the shirt off his back or the swift kick in the butt to motivate you if that's what is needed. I like to go there to visit and watch my brother train and I am always welcomed with open arms. They really are like a family there. All the people that train there push and motive each other to succeed in whatever goal they have set. I highly recommend trying it out!

I am so GRATEFUL to have found this dojo. Sensei Oscar is an amazing teacher. He also is a wonderful example of a man who incorporates not only his teachings but his thoughts of who a truly good person is. I have personally seen awesome transformations of the MMA fighters who train there. My son goes to this facility to train. He has gained not only muscle and weight loss but has become more confident. He is more focused and on a good track. I myself have taken some classes there. It was so much fun and you feel amazing. It brings out something very cool in you. I hope to be able to join someday once I get some medical issues out of the way. It is a honor to train there. Also an honor to know Oscar and become part of the MMA Underground family.    

A great place to train, work out, improve fighting skills and become a better person. I trained for some years a while back and go back every chance I get just to say hi, catch up and even learn something. I've been through 20 years of school, earning my medical doctorate and now finishing training at a prestigious hospital and I can say my time spent at MMA underground was foundational to the learning habits and discipline that have carried me to where I am. Even if I'm not paying dues, I always feel like a member. Highly recommended. 

Underground has been my safe haven for the last 2 and a half years of my life. Before the gym I felt unfulfilled with my life, and that I needed to do something more besides work and hang out with my friends. I had tried mixed martial arts previously at another gym and quit the same week. They didn't take the time to teach me and just made me hit a bag. I regretted the decision of quitting and found this place a couple years later when I moved to Lake in the Hills. In the beginning it was hard because I was out of shape, but coach Dylan Kowalski and head coach Oscar Olivares have been there to push me through all of it. Including all of my training partners who are more than friends but are family we are one. Fast forward to today I'm having success in my fights and currently on a winning streak. I would recommend this gym to anyone who wants to pursue being a fighter, or just training to stay in shape and live a healthy lifestyle.
