From the reviews

Thank you Cortez Martial Arts for the positive influence you continue to have on my son. We signed our son up when he was 5 years old and he is now close to turning 8. Sensi Jason and coaches have all played a positive role in my sons young life.

★★★★★ — Daniel, May 2018

I signed up with my niece at the end of November 2021, three months ago. We go to the adult Muay Thai classes 5 days a week, and love it. I joined to support my niece and to get into shape, but I really enjoy it and have really noticed positive changes.

★★★★★ — Andrew, Feb 2022

I have been training at this dojo since February of this year and it has been amazing. Sensei Jason Cortez is a very friendly and welcoming person. Everyone at the dojo pushes everybody to be better!

★★★★★ — B, Oct 2017

I can’t recommend Cortez Full Martial Arts highly enough! The instructors are incredibly skilled, patient, and truly passionate about teaching. They create a welcoming and supportive environment that motivates students to push themselves and improve.

New to muay thai? Start at Cortez Full Circle Martial Arts

Cortez Full Circle Martial Arts comes up as a beginner-friendly gym, going by their listing and members’ reviews. 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 Cortez Full Circle 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.
