From the reviews

Best Muay Thai instructors hands down. The lineage comes straight from Thailand. Hands on learning and kru Aaron couldn’t care more about the students and his passion for Muay Thai is clear in his teachings. Coach Grizz is very straightforward and an amazing coach.

★★★★★ — Jake&Christine, Feb 2026

I've been coming here for years and I couldn't reccomend this gym more. The instructors truly care about the students, they care about quality teaching, and they care about muay thai. Very rare opportunity that's hard to pass up if youre in the area.

★★★★★ — Tim, Feb 2026

My kids have been going to this gym since they were small and they LOVE it! Kru Aaron and his team are knowledgeable, know how to push them and keep it fun at the same time! The atmosphere is one of inclusiveness and you feel like part of the family.

★★★★★ — Stacy, Feb 2026

Nothing but amazing things to say about Sitmangpong. I trained with Kru Aaron and Grizz for 8 months in 2023/2024 and was blown away by how knowledgeable, passionate, and welcoming they are. It is a very special place where everyone’s goals are well respected and they’ll help you achieve them.

Your first muay thai class at Sitmangpong Muay Thai Boxing & MMA

Nervous about walking into a muay thai gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

Muay thai is a contact sport. Ease in, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
