From the reviews

I love Mass BJJ in Acton, it is been a great experience for me. My friends are awesome and the instructors are really committed to show us the art of Jiu-Jitsu

★★★★★ — Raiderrr, Nov 2017

I started out here from white to black belt and I couldn’t have asked for a better family of martial artists and community to join. Truly some of the best Jiu Jitsu instruction in the world here, the level of camaraderie, community and family that I never thought I could receive at a gym.

★★★★★ — Charles, Dec 2024

I will never be an MMA fighter. That's not why I go to class. But the best part of Mass. BJJ is that no one cares. I have never met a nicer bunch of people spanning all ages and backgrounds. And the instruction is top notch. There really is something for everyone here.

★★★★★ — Bob, Aug 2016

I’ve been attending the fundamentals BJJ class and dabbling in kickboxing since the middle of March. It’s probably not hard to find a school that will help a newcomer put down a good foundation for their development, but where I've found Mass BJJ really distinguishes itself is how much emphasis is placed on a highly…

New to BJJ? Start at Mass Brazilian Jiu-Jitsu - Martial Arts Center

Mass Brazilian Jiu-Jitsu - Martial Arts Center comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never rolled or set foot on a mat, 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 or flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. 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, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first BJJ class at Mass Brazilian Jiu-Jitsu - Martial Arts Center

Nervous about walking into a BJJ 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 basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, 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.

BJJ is a contact sport. Ease in, tap early and often, 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.
