431 Eastern Boulevard, 2nd Floor

One weird, wonderful floor in Essex.

Two practice spaces and a shared lounge built for movement, challenge, rest, creativity and human connection.

Mat Lab Martial Arts, Sangha House Studio and everything between them are part of one community Life Support System. Come train hard, rest your brain, meet your neighbors or try something you never expected to do.

Mat Lab Martial Arts

The Club's home base for BJJ, Judo, fitness and 1:1 training.

Women, family and hobbyist focused: the ultimate introduction to a practice that is usually ego-driven training. You will be challenged and you will be supported while it happens.

We have researched mindful and sustainable training practices alongside world champions as well as first-time white belts over the past 10 years to give you the most modern, integrative and adaptable way to learn this fun and exciting self-defense practice.

The Yoga Mouth Life Support System is the foundation of all our adult programs, so everyone who trains here is supported mentally, with access to evidence-informed, non-clinical mental health care as part of their workout and sport practice.

  • Sport and recreational Brazilian Jiu Jitsu
  • Judo
  • Group fitness and strength
  • 1:1 training

And the bits in between

There is a lounge with couches, murals painted by people who come here, and a kitchen corner that ends up being where most of the actual conversation happens.

Come and look at it in person.

Second floor, 431 Eastern Boulevard. Metered parking out front on Eastern Blvd, and the meters are enforced, so bring change. There is also a free lot behind the building off Virginia Avenue.
