“… And The Reason I Stayed Was Because of the Teachers”

“As I was turning 40 years old, I found it harder to get much out of just going to the gym. As a big fan of mixed martial arts, I wanted to learn a striking art that had both a martial arts tradition and real world application. The Muay Thai program at Nak Muay Gym was the perfect choice.

I first chose Nak Muay because of the convenient location, the quality facilities, and the variety of martial arts offered, (real kickboxing classes , Brazilian Jiu Jitsu, and Muay Thai) and the reason I stayed is because of the teachers. Knowing that most of them actually compete was a big plus. Additionally, their approach to instruction makes everyone feel comfortable as they carefully guide students through techniques with an attitude that is both serious and welcoming.”

Preserving The True Art of Muay Thai Boxing

Knowledge and techniques are passed down from our masters in Thailand, to our students here at home. Nak Muay Gym preserves the true art of Muay Thai and teaches “Thai Style Boxing”. Don’t be fooled by the big franchised gyms out there claiming to teach “muay thai kickboxing”

In our muay thai classes, you will learn the traditions, techniques, philosophies and drills used by professional Thai fighters. You will learn proper foot work, body mechanics, punching, kicking, elbows, knees, and clinching techniques. This is a step by step learning process that will start at the most basic level. Nak Muay Gyms ranking and progression system will enable you to advance in the curriculum as your skills steadily increase. Measurable progress feels good!

Learn A Practical Self Defense System That Works!

It’s an empowering feeling to know that you can actually defend yourself.

Not only is Muay Thai known for being the “king of striking”, it is also a great martial art for REAL WORLD SELF DEFENSE. It can be an empowering feeling to know what you are studying, ACTUALLY WORKS!

Many of the Muay Thai techniques you will be learning are the same very techniques we use to instruct current military, law enforcement officers, and homeland security officials.

YES, Muay Thai is the striking art that every current UFC fighter is scrambling to learn! These skills transition very well to self defense situations, especially with knowledgable use of knees and elbows. You will gain the skills to defend yourself in the Muay Thai program.

“8 months later, I lost over 110 pounds!”

I lost 110 lbs! Nak Muay Gym

“When I first started the Muay Thai program at Nak Muay Gym, I weighed around 350 lbs. I wanted to change that… 8 months later, I lost 110 lbs ! This is the best shape that I have ever been in my whole life and my overall life style is healthier now.

My experience training at Nak Muay has been amazing. The people at the academy slowly become your second family. The instructors are great at what they do and they really care about their students. They make sure to observe each student individually and help them out. My future goals are to lose a little more weight and become a lean mean fighting machine. I also want to help others who have been in my shoes in the past.”
