From the reviews

Arnett’s Martial Arts has been a great part of our family for about seven years. Both of my sons have attended classes year round and are currently working toward their black belts. The confidence that comes with knowing you have the skills to defend yourself and protect others is priceless.

This place changed my life for the better. Every class is very well ran and the teachers are super welcoming. I wouldn’t want to be anywhere else then here!

★★★★★ — Justin, Feb 2023

Dropped in for a free class to try out some BJJ and man, what a blast! Thought it would be a good workout and I got way more than I was expecting out of it. I was gassed by the end and learned a ton in an hour. Very humbling but worth a try if you’re on the fence.

Your first muay thai class at Arnett’s Martial Arts America

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.
