The instructor showed me around to the locker room and informed me of the directions of bowing and greetings other as I got on the mat. There were a few warmups that were a little tricky to do, but with practice it gets better. After the warmup exercises, we were paired up to do some partner drills, and then ended the class with a couple of quick matches. This was definitely a good workout and helps you understand your body awareness in relation to others around you. It's a very close contact sport and definitely good a good workout. I would definitely recommend trying it out at least once and would love to back and try one of their gi classes to see the difference.

Jean Kleber is a top-notch instructor (http://www.kimurabjj.com/about/instructors/) with many years of bjj training/teaching under his "black belt" (pun intended). His accomplishments are outstanding and his teaching ability is second to none. He takes the time to teach you, follow your progress and make sure you're moving in the right direction. He gets to know each and every one of his students on a personal level. Since this is my first time training I can't comment on other training centers, but I've heard it countless times from existing/new members that they are thrilled to be training there because it is so much better than their past centers. (http://www.kimurabjj.com/testimonials/) I would highly recommend Kimura BJJ in Watertown if you want to take up Brazilian jiu-jitsu or one of the many mixed martial arts classes being offered. It's a great and fun experience. Highly recommend

Our son started taking classes from Paul and Jason right when he turned 4, about 7 months ago. Although our son was the youngest, Paul and Jason managed to teach him in a way that was simultaneously appropriate for his developmental level and also allowed our son to feel like he was undoubtedly part of the group. Paul and Jason manage to strike just the right balance between between firm and warm, allowing the kids to have fun and also emphasizing the importance of respect and discipline. Paul is also just an incredibly kind person, and really seems to love teaching and helping his students to learn and develop emotionally, cognitively and in terms of karate skills. We also really appreciate the flexibility of the schedule and the cost - much better than other nearby karate schools we considered. Lastly, the warm, friendly community of parents and families has been an unexpected bonus. We are so grateful we have found USK and we are looking forward to our son continuing to go there and our younger son joining him when he is old enough.

I can't say enough about the bang for the buck and quality of training at United Shaolin Kempo. There's also a free one week trial if you're on the fence and you can pay as you go if you don't want a contract. As far as cons go, I will say, the building the school is in is not state of the art, it's rough around the edges and parking can be tough on Moody, although there's parking right around the corner on Chestnut st. Those things aside, if you do your research you will see the prices here can't be touched and it's a great positive learning environment.

Professor and all of the instructors here are phenomenal. They provide a great level of detail and clarity. They tell you what it should look like, how it should feel, where you should shift your weight. They also adjust according to your level and ability, even when there's like 20-30 other students. The environment and other students also make this gym awesome. I've been to some other place where students just want to demolish you, even if you're a lower belt. Most experienced students here will adjust their strength when you roll with them and will guide you along, especially if you're newer. When people get better, I've noticed they pass this along as well. On the flip side, if you want to go up against someone really good, you have plenty of options here. If I ever move back to Boston, I'll definitely come back here to continue. Seriously the best BJJ gym in the city! Easily 5 stars!

Gracie Barra Boston have owed us a substantial refund for months, and they did not respond to our…read moremany emails and BBB complaint. We enrolled our two kids in their program in August 2025. Shortly after, we requested a membership freeze (which they confirmed in writing), and later submitted a cancellation request that they also acknowledged. Despite both the freeze and cancellation being confirmed, they continued to charge us. We reached out multiple times over several months to resolve the issue. At one point they acknowledged the problem and said refunds were being processed, but the charges continued. We ultimately had to change our credit card number to stop the billing. It's unfortunate, because the program itself seemed good and our kids enjoyed it.

BJJ is a tough workout, but very rewarding. I highly encourage anyone local to come take a class. Or if you are just in Boston for a few days, it is 100% worth a visit.

Top-notch BJJ training environment for the gi and no-gi with very welcoming instructors and classmates! Nate and Scot were both phenomenal and lighthearted instructors that took their time to really explain techniques, positions, and their decision making process. The most defining characteristics that stuck out to me was how down-to-earth and goofy Nate and Scot were during all classes. It makes you feel at ease and relaxed. No ego at all. Don't get me wrong -- they will absolutely destroy you during the advanced classes, but it was fun having the chance to roll with both of them and feeling the huge difference in skill level. All the classmates there are friendly, too! If you go to the non-fundamental classes, you'll have a great time rolling with the upper belts. The competition team was fantastic with Luis and Josh leading the way. Competition training was always fun and intense, but never out of control. Special thank you to Luis and Josh for taking time out of their weekends to come coach during competitions! You'll have a solid competition team to go compete with. If you have the chance to learn from Pat and Nick during the weekend classes, I would highly recommend it! Learning from these two high level black belts is always a good time. If you get a chance to roll with them, even better! Be prepared to be effortlessly destroyed by them. Only has a couple chances to learn from Ed before I left, but he was awesome!! 10/10 would recommend this place. I miss this academy and everyone in it! You'll love going here -- trust me!
