Excellent instruction and fantastic culture! Probably the best gym Ive trained at.

AMAZING! Cant say enough good things about Mike and his program. His attention to detail and genuine love for teaching shows in every session at the school!

Awesome gym. Mike is an expert and really focuses on teaching the true fundamentals of BJJ in a way that’s easy to understand and apply. Great atmosphere along with a large amount of friendly and truly dedicated practitioners. Would recommend this gym to anyone looking to get into BJJ.

Mike Pellegrino and the whole team of instructors at Mass BJJ Arlington have been great. I am new to Ju Jitsu, a bit older, and not in the best shape of my life, but they have made sure that I can get the most out of the program. They have challenged me while simultaneously understanding where I am starting from. Cant recommend it highly enough.

MassBJJ is an amazing gym! Not only is the staff supportive but so is everyone on the mat. The team here feels like a family. BJJ classes are a fun but also well thought out and safe environment for learning BJJ/self defense and overall fitness with the weights room.

Mike and his instructors are amazing! My 13 year old son has been attending for about a year and we couldn’t be happier. He has learned so much about the art of jujitsu . He has had so much fun, greatly Increased both his fitness and confidence. Through out the pandemic , they have maintained safety and followed all protocols . I recommend BJJ Arlington highly . Additionally, Mike is also a physical therapist which is helpful as challenges may come up .

My son is a lazy butt. But he visits this Jiu Jitsu center with pleasure!P.S. This center has a very good ventilation.

Best place to train Jiujitsu around. Whatever is your goal competition or just a hobby, this is the place. I felt welcome since my first class, it’s a super friendly environment.

Mass BJJ has been a great place to learn BJJ, and other martial arts. Mass BJJ have five star teachers, and Mike ( the owner) is very welcoming. Even during Covid- 19, there was washing of equipment, and mask wearing at all times. Mass BJJ has been a great place, and a currently 67 5 star reviews just goes to show you the work that they put in.

Really special environment full of wonderful people. Great facility and equipment. Honestly, whether you are young or old, elite athlete or not, highly competitive or just trying to do your own thing...it’s just hard not to love this place. There’s something for everybody. It’s rare to find a place with top quality technical instruction that is so accepting and open.

Ive been at MassBJJ for over 3 years now and its been absolutely fantastic since the moment I joined. Not only is everyone friendly, professional, and caring, theyre complete savages on the mat. I would highly recommend this gym to anyone looking into BJJ.

Great place to get started or hone your skills, excellent instructors and a great facility make for an outstanding place to train. Very welcoming to all levels and everyone is super friendly, can’t recommend Mass BJJ enough.

By far the best place Ive ever trained at! The instructors are amazing and everyone is so welcoming! If you are looking to not only learn jiu-jitsu but to also be a part of a community, this is the place for you.

Mass BJJ has an excellent training environment with highly experienced instructors and great training partners. The workouts are safe but high-intensity with participants learning technical skills while increasing fitness. The facilities are clean, spacious, well equipped and have good ventilation. I highly recommend Mass BJJ.

Great community and atmosphere! The owner Mike has taken every precaution to adapt during this pandemic. The instructors are friendly and fantastically knowledgeable. Im so happy I joined and couldnt recommend Mass BJJ enough!

This is an excellent school. My 9 year old daughter has been training here for about a year and she really loves it! Its a very supportive environment that challenges everyone to do their best and be encouraging to one another. Mike and his team have also gone the extra mile to be very conscious of safety and all health regulations during Covid. I really recommend Mass BJJ!

The absolute best BJJ option in the area—and one of the best schools Ive been to in my life. Great instruction; giant, top-of-the-line facilities; wonderful people and family-like environment. Cant recommend highly enough!

If you’re interested in learning / training Brazilian Jiu Jitsu, you will find top-notch instruction here, as well a a solid and welcoming community of kind, ambitious, genuine people. (Also, super nice and clean facilities.)Mike fosters a positive, respectful and focused learning environment. People of all ages and walks of life train here. It’s not a “sink or swim” type of environment, and it didn’t take long for me to feel like part of the MassBJJ team.Aside from all of the benefits of BJJ, this place has something special to offer. Stop in and say hi - you won’t regret it.

I have been training at Mass BJJ for 2.5 years. Right from the start, everyone I met from teachers to teammates were open, welcoming, and friendly. As someone new to training Jiu-jitsu, I had not point of comparison for how Mass BJJ fared in terms of instruction, but I felt certain I was getting first-class learning in an amazing atmosphere. It was only later when a friend who has been doing Jiu-Jitsu for much longer, and travels all over the country to different gyms told me Mass BJJ was one of the best gyms he had been ever been to; I realized I was lucky to be learning from such great instructors. First-class on every level, happy to call this place my second home.

Super welcome to beginners. Owner gives his life to the school. Higher belts are serious about getting but also about helping you get better. Great atmosphere.

MassBJJ changed my sons life - he went from a pretty tense and emotional 11 year old to a calm, confident, strong, happy 13 year old. He made friends, became fitter and stronger and was more able to focus on school work and more relaxed in social situations. Absolutely life altering for him and us.

We love the attitude and encouraging atmosphere at Mass BJJ. My 9 year old daughter joined with a friend and the two girls felt right at home!! Their teachers have kept them engaged throughout Covid and they are always eager to do both the fitness and sparring parts of the class. BJJ is building some fierce and spunky girls!!

I’ve been training here for more than 7 years. I couldn’t ask for more. The people are what make a gym, and the quality at MassBJJ is superb. It’s a motivated team environment. If that’s not enough for you, the equipment and facilities are great. Large mat surface, and plenty of weights and workout equipment.

This is an amazing gym. I have been training BJJ for eight years, and have trained in gyms all over the world, and Mass BJJ tops them all. Whether is the size and cleanliness of the facility, the range of equipment, the quality of the people in the gym community and the way they take care of each other, or the energy, attention and care that Mike, the owner and lead instructor, brings to every class and everything he does, theres no better facility or instruction to be found anywhere around. Before I started jiu jitsu, I was an elite international athlete in another sport. I have been coached by, or coached with, the best in the world. What Mike is doing with Mass BJJ is in that league. Frankly, if you live close enough to train here and you arent, you are making a mistake. If youve got the raw motivation, this is a community you will never want to leave.

Mass BJJ is the ideal training environment. I lived closer to several gyms but the trek to Mass BJJ was worth it for the following reasons.- Clean and spacious facility- Clear, technical, and wide variety of instruction- Training partners who share the same goal of improving themselves and others- Class offerings for beginners and competitors. Competitors will appreciate the hard training and positional rounds.Overall, a great place to train. Ill surely miss it!

I have had the chance to train at some other BJJ gyms before coming to MassBJJ, and what has kept me there is the professionalism and degree of knowledge and passion that Mike has for BJJ and teaching, the tight-knit community, and the commitment that everyone shares to do their best. This is a group of good people who work hard and dont compromise integrity or quality!

Amazing gym, amazing people, all around recommend. Great culture that is open to beginners of all abilities

Great place, lots of COVID safety precautions. Very good teachers, and you can tell that the owner (Mike) really cares about Jiu-Jitsu. Good lessons for all skill levels.

Excellent BJJ school.

Ive been training at Mass BJJ in Arlington for a little over a year and I could not recommend it enough to anyone thinking of joining. Whether you are an experienced grappler looking to compete or its your first time stepping on the mat you will be welcomed. Class instruction is at a very high level and they even off an online platform for you to supplement your training with (also highly recommended). The only thing better than the instruction that Mike, Christie and all instructors is the community that they have built.

Great BJJ gym, the kids program is amazing and has an emphasis on hard work and learning the art. With the virus, the gym has taken the proper cleanig guidlines at all times. I would recomend this gym if you are intrested in learnig Brazilian Jiu Jitsu!

I have been training at Mass BJJ for a little over a year and my experience has been wonderful. The Staff (Mike and Nate) are fantastic. They are always welcoming and run a professional gym. Both are very accessible and willing to help with any questions. Clean facilities and great class mix and structure. My only request would be to add more classes on the weekend.

Good to be back! Very clean, lots of ventilation, all the protocols and all the best people

Great team! I stopped in from NY for an open mat and felt very welcome. I will definitely be back for all future trips out here!!! I highly recommend

Ive trained at a number of BJJ gyms, and MassBJJ sets the bar. Incredible group of people, and Mike is an exceptional instructor (Robero Maia black belt) and a great coach. Just a couple things that set it apart:-Huge investment is always being made back into the gym and the facilities. Extremely clean, bathrooms, shower, water-fountains, locker-rooms.. everything is top notch.-There is a FULL gym and thats also included in your membership-Mike is the real deal and rolls with students full on.-Great culture, great people, and a true no ego attitude pervades the place.-Often there are additional classes like wrestling, Muay-Thai etc for a full scale MMA experience if thats your cup of tea.All in all, MassBJJ is a fantastic place to train and a very welcoming community with a great vibe. Highly recommend checking out a free class there if youre considering it! Youll be back.

Plenty of great amenities: clean facility, changing rooms with lockers and showers, variety of fitness equipment from stretching, cardio, to free weights, plenty of mat space. I love that theres a big womens team in the gym at various belts! Instructors are attentive, personable, and they take the time to share their passion for the sport with everyone. Some nights can be busy, classes could have about 30+ people on any given night but the instructors still give their undivided attention when you need help.

This is the ultimate playground. Weights, physical therapy, and the largest mat area I have ever trained on. Clean facilities, shower, and changing rooms. I found everything I needed. As a beginner, I had a warm welcome, with patient sparring partners, correcting my positions and answering questions. Also encouraging to see so many dangerous women training here, too. Dangerous in a positive way. :) mike is an excellent technical instructor. I also caught Jon’s class. My skills are growing.

Awesome gym. I dropped in with a friend and coach and the team were very helpful. Faculties were very clean. I would highly recommend this gym to anyone in the Boston /Cambridge /Arlington area.

I trained at Mass BJJ for a week while visiting from Houston. I immediately felt at home, everyone I trained with was extremely friendly and helpful and I learned a lot of new techniques in the short time I was there. Would highly recommend to anyone, I will definitely visit again next time I’m in Boston.

Im not from the area, I was just visiting for a weekend. Lots of class times, very visitor friendly, good quality instruction and big enough class size without being too big. Saturday open mat was decently sized especially considering that the fight team was out at Pan Ams. Open mat fee is reasonable. Id definitely come back again.

Whether you have trained before or are brand new to jiu jitsu, this is an amazing place to train. If you are interested in starting a martial art, but have been too intimidated to take the plunge, know that the owners/instructors at Mass BJJ have created a culture that is welcoming and supportive to everyone that comes in. The instruction at Mass BJJ is very technical and the instructors all have tremendous enthusiasm for their art and take the time to make sure that every student gets the most out of their training. If you are in the Arlington/Somerville/Cambridge area and are interested in training gi or nogi jiu jitsu or kickboxing, do yourself a favor and check out Mass BJJ

Great kickboxing workout. The teachers are very good and the atmosphere is fantastic. Workout is adjusted to the skills of the students and partly split so that the advanced students can learn more complicated techniques while the noobies learn the basics. Highly recommended

I was BJJ school shopping after leaving my last school, which was a hotbed of toxic masculinity and gaslighting. Mike is the head instructor and was great to meet with, super inviting, and even recommended I catch a womens class to get a better feel for the community that would become my jiujitsu home. This place is amazing - the facilities are clean, the instructors are all top-notch. Theres instruction for whatever your BJJ game wants or needs. The adult classes are split in Fundamentals vs All levels, which is a nice way to delineate what youll learn and work on. Fundamentals classes focus on techniques, and All Levels classes have more time built in for rolling. Christie is the black belt who teaches the womens class and she does so much for the community of women BJJ practitioners in the area. Nate is the other main instructor and hes a technical wizard and a very talented teacher. I dont get to train here as much anymore due to my new work schedule but this is where my BJJ family really expanded and where I go for BJJ community.

This place is great. Wonderful instructors. Our kids love Mike and Marcin!

Huge mat space, helpful and well-rounded instructors, very clean facility!

This has been my home gym for 2 months and I love it! Here are the reasons why:A) Good foundation for beginners: I’ve been practicing BJJ for a year at other gyms, and it was really hard for me to get started as a beginner because other gyms I attended did not have a basics class and advanced classes taught more techniques than I could remember. I often ended up confused and not retaining information. In the basics class at MassBJJ, we focus on a few techniques that are reviewed throughout the week.B) Good sense of community: The first week I joined, instructors and other people introduced themselves to me, and someone would come up to me during partner work so I wouldn’t be the newbie nervously searching for a partner. People are happy to teach you and help you if you are lost.C) Strong women’s community: There are 20-30 women who regularly train and this gym, and the gym makes it a point to create a community for this group of women. There is a women’s only class once a week and a women’s social event once a month. The women I trained with inspire me to practice more and to never make excuses. They work hard and help each other. Sometimes the more advanced women lead classes.Only disadvantage: this gym excels in BJJ instruction, but the kickboxing program is not as robust compared to other MMA gyms I’ve been to. I decided to focus on the BJJ aspect of my MMA practice after trying out several kickboxing classes.

Instructors are knowledgable, people are friendly, facilities are clean and designed with the clients in mind. Mike and Nate are great and I highly recommend this place if youre looking to get involved in martial arts!

THIS PLACE IS AWESOME!!! Ive trained at many gym before none have compared to this one! GREAT instructors very well thought out curriculum.And loads of equipment to be used , overall one of the best Jiu-jitszu gym out there for sure!!

Great people and very inviting. I cant recommend this place enough!

Really great people, making newcomers welcome, and very competent instructors - with a great mix of friendliness and expertise.

Mike Pellegrino, head instructor at MassBJJ Arlington, is an amazing teacher. His classes are always fantastic and chock full of details that are always making my jiujitsu better.

Mass BJJ is awesome. When I showed up I was a little apprehensive about Jui Jitsu, but the instructors immediately made me feel comfortable. Its great to have access to a full range of training partners from beginners like me to really advanced Jui Jitsu players who are willing to share their knowledge.
