From the reviews

I've been coming to this gym for 5 years at least. What attracted me to it was that it's small and not corporatized, which comes with benefits such as people knowing your name.

★★★★★ — Richard, Jan 2025

I did not know what to expect when I bailed on my yoga membership and signed up for a three day trial at American Gym Boxing. I showed up so nervous and was immediately treated with respect, smiles and kindness. I ended up going nearly 6 days a week just because I loved it so much. I never had so much fun working out!

★★★★★ — Clarke, Dec 2019

Unbelievable experience daily! I've been an athlete my entire life and have developed relationships with a lot of coaches, trainers, ect. throughout. As a competitive athlete/trainer myself it's easy to walk around with a chip on your shoulder, it happens all the time.

★★★★★ — Jason, Apr 2017

I enrolled my son in the kids' classes here last week, and I couldn’t be happier. This gym has such a welcoming and supportive atmosphere! everyone is friendly and great. The coach is incredible, especially with the kids, balancing fun with the right amount of hard work.

New to muay thai? Start at American Gym

American Gym comes up as a beginner-friendly gym — noted on their own site. If you've never thrown a punch or a kick, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit to start — you get in shape by training, not before it, and coaches scale the conditioning to you. Second, you won't be thrown into sparring — reputable gyms build fundamentals (stance, footwork, and the basic strikes of the "art of eight limbs") for weeks before any contact, and sparring stays optional. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first muay thai class at American Gym

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.
