"Great gym and even better people! I was visiting from out of town and dropped in to see if I could get a roll in. The coaches and people were really friendly, super knowledgeable and very respectful. Even learn some new leg lock defense! Highly recommend to anyone looking to either drop in or join a community - this gym is a hidden gem!"
"Was in Boston for a couple days and did two classes in a row. Good stuff, some nice rolls and scrambles. Mat space is huge and the gym looks very nice. Everybody was great and If you are in Boston especially around downtown I would definitely recommend visiting."
"I joined South Boston BJJ this past January (2025). I had been at my previous gym for almost 4 years and was a bit nervous about coming into a new gym, but Ruben and everyone else at South Boston BJJ were extremely friendly and welcoming. Ruben has cultivated a great room with highly technical jiu jitsu, a great culture of safety, and a really fun and informal atmosphere. I learn something every time I train there and also have a lot of fun doing it. Great gym, great people, and also amazing dogs."
"been training at SB BJJ for about a year so far. What I like about this gym that makes it stand out from other gyms in the area are: 1. Memberships are flexible: you can pause your membership when you travel. 2. Coaching style is very methodological and the coaches are nerdy. For the first time I started to understand principles of grappling but not just a collection of different moves. 3. As a 132-pound-woman, most male training partners are bigger and stronger, but they are super safe to train with. 4. What's more appealing is that all the female training partners here are strong and passionate about jiujitsu. Training with them has been a blast. 5.The golden retrievers are super healing."
