From the reviews

Training at Tsunami Academy has been an extremely rewarding experience for me. Through the instructor's breakdown of technique to the combat focused drills, I feel like I am gaining a deeper understanding of the material and it keeps you engaged the whole time.

★★★★★ — Ricardo, Jul 2025

I'm a pretty new BJJ white belt who was looking for a place to train while in the area for a few weeks on a work trip. Luckily, I found Tsunami. I was able to go six different nights and was able to train under three different coaches.

★★★★★ — Matthew, Jul 2023

Excellent instruction, welcoming staff and students. I have attended classes as a drop in in multiple states and foreign countries over my sixteen years of training and enjoyed the instruction and culture established by the owner.

New to muay thai? Start at Tsunami Academy of Martial Arts

Tsunami Academy of Martial Arts 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 Tsunami Academy of Martial Arts

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.
