From the reviews

Trained here for 2 years after transferring from a different MMA gym. This place is soooo special. The people, the coaches, the training partners. Unlike anywhere else I’ve ever trained. I am moving and going to miss it so much — especially my crew in the basement! #CalestineCartel forever.

★★★★★ — Rose, Feb 2025

This gym is in a great location in Brooklyn and very convienently close to the train. Its super clean and has showers. The workout is intense and perfect for fitness ans weightloss. The coaches are also really nice and helpful to guide you every step of the way.

★★★★★ — Vincent, Mar 2020

Best place in the city to learn BJJ and Muay Thai! The academy has everything you need and Jon Calestine is an international level Jiu-Jitsu coach. Not every gym has people flying from all over the world to take a lesson - but this is one of them!

★★★★★ — Christopher, Mar 2023

Great authentic Muay Thai gym, definitely one of the best in the NYC. The coaches are very knowledgeable, who've fought professionally, and also trained in Thailand. The gym is very clean, spacious, has several heavy bags, kettlebells, and a weight lifting section.

New to muay thai? Start at Kings Combat Williamsburg

Kings Combat Williamsburg 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 Kings Combat Williamsburg

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.
