From the reviews

Natick is extremely lucky to have such a skilled teacher and practitioner as Justin. His positive energy and welcoming attitude along with detailed instruction create a perfect environment for learning and growing.

★★★★★ — Charlie, Oct 2021

Justin, the owner and lead instructor, is one of the best blackbelts I've had the pleasure of working with; his vast knowledge, and ability to break down and communicate complex techniques in clear, easy-to-understand ways, is a skill not often found in a coach (and is especially important in a complex combat sport…

★★★★★ — Michael, Jul 2021

My son got into Jiu Jitsu when he was in high school and this is the place that started it all! To him, Justin is the GOAT and he still returns for classes when he is back home from college. And now, our 12 year old daughter is loving every minute of her classes with Justin. Highly recommend.

★★★★★ — Tatyana, Mar 2024

Justin is a great instructor ... everyone is cool and there are plenty of classes. Cant ask for anything else. I love training at Bay State!

New to muay thai? Start at Bay State Brazilian Jiu-Jitsu

Bay State Brazilian Jiu-Jitsu 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 Bay State Brazilian Jiu-Jitsu

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.
