The instructors are great, the fellow class participants are great, and there is a culture void of any pretentiousness or ego. The classes are fast paced, full of valuable information, and a great workout. If you have the slightest interest in trying any of these types of classes, stop by gym for a free week of classes. Even if you have no interest, go anyway. It's that awesome. For reference, I've been to 20 or so different gyms all over the US, and trained extensively at big name affiliates like Thai Boxing Association, American Top Team, and Nova Uniao. Bang Muay Thai is the best gym I've been to.

I love that I get the structure and energy of a group class but without the stress of a set class time. My son started the kids karate program recently and loves it. As a busy parent, being able to get my own workout in while he's attending class is a huge win. I have also been going to the striking classes and not only have they taken my skills to the next level, but they are a ton of fun. Besides getting in a great workout, the Surge community is warm and welcoming. You're greeted by name from day 1 and the trainers are all awesome and know how to push you, no matter your fitness or kickboxing level. I'm just so glad I found this gym. Thanks for everything, Mike and team!

Should have read the reviews about the PUSHY sales. Bought a Groupon for 10 Classes, first I tried…read morecalling multiple times to see if I needed to sign up for a class but no one answered so I just drove over before a class started only to be told I had to schedule a one on one first and was turned away. Which ok fine....BUT then after you finish your one on one is when the EXTREME sales pitch starts, I specifically told them I wanted to try the 10 classes because there was only 1 class time I could make and wanted to see if it was possible for me to get up that early multiple times a week. Instead I was pushed and pushed into a membership....and of course only ever made it to like 3 classes. And I might add that those situations make me very uncomfortable and give me terrible anxiety so I just always give in. I instantly regretted signing up for any kind of membership before even getting to try out a real class. FAST FORWARD.... I asked to cancel because I just couldn't make it or afford it they make it EXTREMELY difficult to cancel. I had wrote them saying I could not afford it and they come back with ok pay $50 dollars more than you can already not afford and by the way we need 30 days notice so we are going to charge your account again for the $150 membership you don't ever use! All in all there are much CHEAPER gyms out there with TONS of classes and ZERO pushy sale pitches! Save your money and don't get tricked with the "good deal" they try to offer you!
