I am more than impressed with this Muay Thai gym. The instructor's expertise is unparalleled – his technique, his exceptional teaching skills, truly sets him apart. He has a remarkable ability to explain the moves, to show them and demonstrate them, in a way that's easy to grasp, making every sungle session an amazing learning experience. His remarkable fighting history is not marketed when you check his Google gym. However, his impressive palmares speaks volumes about his dedication, skills and knowledge in the sport. The affordability of the classes is incredible. The value you receive for the price sounds crazy. When you compare the quality of instruction and the experience you gain, it's clear that this gym stands head and shoulders above the rest. Having tried around 10 different Muay Thai gyms across Thailand, I can confidently say that this one is in a league of its own. The level of instruction and the overall atmosphere make it an exceptional place to train. If you're serious about Muay Thai, look no further, this is where you wanna train!

If you are coming to Thailand to learn Muay Thai this is the place I recommend. Chiang Rai is a sleepy but friendly small city with affordable lodging. I spent over a month training with kru bank as a complete beginner. Most mornings I would have a private session for an hour. If you can afford it I recommend this as you will learn a lot more. I asked him probably 20 questions every time I saw him and he was always happy to answer. Very friendly and thoughtful. Most importantly he is a world class trainer. It's hard to imagine I could have found anyone better to teach me. His philosophy is all about balance. He helped me understand exactly how every part of my body should move for every punch/kick/etc. He explained exactly where my weight should be and how it should shift throughout a movement. I am the type that needs to understand every small detail of what I should be doing in order to have proper form and he was always great at explaining it. His English is excellent and he is very fluent. You can purchase a set number of hours of training and he will tell you when he has openings in his schedule for you to come in. He was often booked but still made time for me in the evening. He has some wonderful cats that live in the building and if you ask him about them he will tell you a beautiful story.

This gym is awesome! The Muay Thai instructors are highly skilled and will help you learn and improve. Pad work was awesome. All skill levels welcome.

Definitely one of the best Muay Thai Gym in Thailand. I found the approach very pedagogical, the lessons super affordable, and I would highly recommend taking private lessons with Kru Bank :)

The Muay Thai / Muay Boran training I received from Kru Bank at The Underdog Muay Thai Gym in Chiang Rai Thailand has been amazing! Being highly skilled and a world class trainer, Kru Bank and his team really care about the work they do and really take the time to do it the best they can. The atmosphere within the gym is very friendly and welcoming by both the instructors and students and makes it very easy, calming, relaxing and sabaai sabaai to walk in there as a complete beginner. Thank you very much for sharing your time and knowledge with me Master Kru Bank, I will see you again soon 😁

Had such a great session here. I've done a lot of martial arts (but never Muay Thai Boxing) and this has to be one of the nicest, friendliest, most welcoming clubs I've been to. The teachers really knew what they were doing and took a lot of time out to train and sparr you one on one and we're very encouraging and great at explaining how to doeach move. This club is perfect for beginners and professionals alike and it was really cheap for only 150 baht. I honesty loved it, and I wish there was a place like this back in the UK!

Booked 2 private classes with Kru Bank. Very knowledgeable and friendly and helped me a lot with technique. Would definitely recommend. Very good price too

Bank was a good teacher for me today. He showed me the real fundamentals. I done some boxing back home and this man was patient and taught me propper technique of muay thai. None of that beginner class stuff.

My girlfriend and I took a private class with KruBank and it was just awesome! We had no experience in muay thai, but we learned a lot and had so much fun! Only bad thing is i cant go there again with my girlfriend because he is too handsome... ;D

I had my first Muay Thai class here and Kru Bank was so great. It was so much fun and a great workout. They were so nice and we laughed so much and the class was my favorite experience in Chiang Rai. It was 100/10.

this is the place to go in chiang rai! i did a private class, the trainer was super focused on having good balance so he showed me all the (not so) little details to change my form in order to achieve better balance and also be faster and stronger. i got so much out of this one lesson, i highly recommend it!

We booked a training session last minute on a Saturday. They were really sweet to accept our request and worked over time to give us the best of the best experience. The trainers were very patience with us as it was our first time training Muay Thai and were so kind. Also they were very handsome and beautifull (no Kru Bank did not ask us to mention how handsome he was ;)). Will definitely recommend this to my network and I will definitely visit for another training session when I get the chance to in the future. ♥️

As I was visiting Chiang Rai for a few days, I was also looking for a Muay Thai training. The Underdog was the perfect place. Great place, walking distance from the city center, great teachers, et good prices. I recommend, even it is for one training and you are beginner, they are very flexible. Thank you Underdogs !

Really like the training atmosphere at Underdog. I train in a small town in Alaska and there was the same friendly touch to the place, felt like home far way from home. On top the trainers are great and detail oriented. Small gym but the space is used well.

I really loved it! Good for beginners. The teacher is really skilled and I have learned a lot.

One of the best Muay Thai gym in Chiang Rai

Bank (our instructor) was a great guy, and didn't mind that we were complete beginners. It was a great work out and something pretty different to do if you're in the area. Would 100% recommend!

The amazing coach helped me to boxe again. It was my favourit moment in Thailand. Many thanks 👍

Great Gym. Bank (I hope that’s how you spell it) let me train even though I was the only student who showed up for the late class. Got a killer workout in and learned a bunch. Very kind environment and would recommend it to anyone.

Today I participated in a 1,5 hour lasting lesson of Muay Thai, including explanation of the basics. The owner, Bank, was a amazing guy. Really happy that I decided to try the sport at The Underdog. With the good explanation of Bank and his trainer, it even convinced me to continue practicing Muay Thai (Thai boxing) back home. If you are looking for good trial of Muay Thai in Chiang Rai, definitely go to The Underdog!

Absolutely loved our session here. The team were very welcoming and accommodating to us beginners. They worked us hard but it was so much fun, and we both felt really great afterwards. They accommodate all types of level, showing us basic movement and strikes; then onto warm up and 5 rounds of pad work. Smiles and good vibes all round. We would 100% return if we are in Chiang Rai. 150 baht is a great price, Chiang Mai some places charge 400 for the same amount of time. I wish the boys all the best, they were excellent teachers

Thank you for sharing your expertise. I enjoyed learning from you and I look forward to returning. Quality Muay Thai experience.

Nice trainers, relaxed vibe. Kru bank has a lot of knowledge. And so do the other trainers. Good for beginners and people who want to learn more about Muaythai and Muay Boran
