From the reviews

Amazing gym that offers authentic Muay Thai and BJJ. This is a first tier choice for people who are both beginners and experienced. Extremely clean and very professional. Classes here are fun and engaging, while also being safe! Kru Rob and the staff put their student's first and make sure everyone's needs are met.

★★★★★ — Ray, Sep 2022

I like that the gym is spotless clean, and has a nice cozy vibe. It has both bjj and Muay Thai which is great, the class is more technique focused than those general kickboxing fitness classes. good for learning some actual skills for self defense or pure interest. Class is small and supportive, has a nice family vibe.

★★★★★ — K2, Feb 2019

If you want to learn some cool new skills and meet some great people, this is the place. I’ve been attending courses here for about six months and am already feeling the change. I am much better than I was to begin with and continue to improve. It is far better than riding a stationary bike staring at a wall.

★★★★★ — Todd, Oct 2022

Been in this gym since of October 2016 and I’m glad I join this gym. Prior to having Muay Thai experience already coming here has made my technique a lot better. With just fixing minor errors like my fighting stance or throwing a hook the coaches are willing to help you improve!

New to muay thai? Start at Square Circle® New York

Square Circle® New York 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 Square Circle® New York

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.
