This gym has given me some of the best changes in my life! Made me more active, more confident and more motivated to be a better person. Great coaches! Great Staff! Even better clientele to make friends with and learn from too. Anyone would be lucky to study/workout here!

Absolutely excellent place to train. The instructors and students are more than welcoming - I was made to feel at home from the very beginning. It doesn’t matter if you are just starting out, or already have experience - they will help you reach your goal, whether you are just looking for a way to get into shape, or are interested in competing. A great bunch of people - I would recommend to anyone.

Darkside Muay Thai has really been a very positive and constructive change in my life! I have become a better and more productive version of myself, a more disciplined person and best of all, I have made amazing new friends. The atmosphere is unlike anywhere else I have been and I have never felt more welcomed into a community in my life. Great classes, great workouts and phenomenal instructors! I highly recommend this gym for everyone!!!
