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! Thank you to Nate, Scot, Pat, Luis, Josh, Ed and Nick!!!

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!

I've been a member at MK for a year now and wouldn't think of going somewhere else! Between the…read moreamount of gear and equipment, and the great people, I love this gym. A few things about MK: -MK is certainly a mixed martial arts gym. At first sight most of its members come in for boxing. MK offers kickboxing, Muay Thai, and Jiu Jitsu classes that are legitimate classes taught by instructors who are experienced by either being current fighters or who have previously fought and now teach. These are not those typical cardio classes that you see advertised elsewhere. The classes are not directly aimed towards training someone for a fight. You will learn basic skills and techniques and if you're willing to learn can definitely pick up more advanced techniques which you can apply if you want to actually train for a fight. There are a few instructors and members who may be willing to train you for a fight, just ask around or ask the owner. There are also cardio kickboxing classes and other conditioning classes that are great workouts that are more creative than what you may usually think of. -Sparring: MK is one of the only, if not the only gym around that allows sparring and contact between members. Title boxing, ilovekickboxing, etc will not offer this as it's a liability and members are to adhere to whatever is being taught in class. The only other types of gyms that allow sparring are mma gyms that are geared towards training you to be a fighter. MK's boxing class has designated days for sparring unless the instructor adds sparring onto other days as well. There are no specific kickboxing or Muay Thai sparring days at this time though MK allows any of it members to spar, meaning if you have a partner at the gym who wants to spar, you can use the ring or cage if it's free to spar on your own time. Grappling is done during jiu jitsu or with a partner on the mats, or in the ring or cage. -Equipment: MK has a weight area and typical gym machines to use at your leisure as well kettle balls, ropes, a sled, tires, etc. There are mitts, shields, and body pads to be used in both the classes and on your own time with a partner. There's plenty of heavy bags as well as a variety of other bags (wrecking balls, speed bags, double end bags, etc). All of these are open to members at any time unless there's a class that are utilizing most of that area or equipment (though there's still plenty space and equipment to use). -Facility: this gym is not a chain, but has one owner. Equipment will range from a few years old to some newer stuff. This means that it's members definitely use the equipment. It's a gym, there's sweat, it's going to be hot, and slightly smelly. You're not going to walk into a top notch facility, but you are going to walk into a much larger one that has many options. There are locker rooms with showers too. -Members: there are many regulars who come to MK. Everyone is friendly, willing to help you if you have a question, and willing to workout with you depending on what the planned workout is. I probably say hi to 90% of the people I see in one day when I'm at the gym. A lot of us know each other by name, some of us are friends, and overall it's a positive environment! You can probably hear me laughing across the gym anytime I'm in because we actually enjoy our time at the gym and have fun. The gym is very male heavy, but there are a few women who come in on a routine basis. The guys here though are not meatheads like a lot of other gyms. And if you are a female, like me, will not make you feel uncomfortable. And if for whatever reason there is that person who makes you uncomfortable, just let an instructor or owner know. They'll nip that in the bud real quick. MK is overall a great place to go whether you are looking for a great workout or want to learn mma techniques. Whether you are a beginner, or someone with experience who wants an affordable gym they can go to workout on the bags or do partner work. Whether you want to take a class or workout on your own. It's pretty much my second home! Check it out!

I had done martial arts for many years, beginning with Judo training under Sensei Jim Pedro Sr. and…read morelater his son two time Olympic Medalist Sensei Jimmy Pedro, During those years I was competing in amateur boxing and taking BJJ becoming a Purple Belt and having occasional success in regional level competitions. I ended up tearing my rotator cuff, my first surgery actually caused more damage and I had 3 more additional surgeries to repair it as best they could. This was in 2013, for over 12 years I no longer trained in martial arts and I was nervous to step on a mat fully aware that my skill level was no longer equal to my belt level, I had also went from being in my prime to being in my mid 40s which doesn't help with the athleticism aspect. The BJJ Community can be harsh when the skill doesn't match the rank, my first day I was willing to start as a white belt (kinda hoping to actually) I was gassed in two minutes and I go sit next to Travis who I remember watching along with other Olympic Team members training I got to be in some of the classes they were in I was a judo Brown Belt and was amazed at the dedication and skill these athletes had especially Travis, the injuries he overcame and trained through takes a different breed of human. Obviously I'm intimidated he isn't going to remember some random dude from judo 14 years earlier. I apologized to him for how out of shape and just plain bad I was and I offered to exchange my belt for a white belt which he quickly dismissed and the fear of judgment went away I'm still amazed at his talent and nothing against my previous professor because the art had evolved since I was a Purple Belt but his Blue Belts are as good and better than the Purple Belts of 2012 and I can confidently compare having competed as a purple belt in tournaments like Naga and Grapples quest and winning medals against others purple belts, it not just the evolution of Jiu-Jitsu it's also the systematic approach to grappling, in my opinion it actually in a way makes students who don't train with intent on purpose end up training with intent by design. It's only been 2 months I still suck but suck less, and the atmosphere of the other instructors as well as training partners have made a decision i thought I might regret into the best decision I've made recently. None of the judgment happened it was actually the opposite and when I would get down on myself after getting smashed while rolling that training partner was usually also encouraging me and reminding me that it will take time for the head knowledge to get in sync with the muscle memory. The entire team is supportive of whether you want train as a hobbyist or if you want to compete & you won't be pushed one way or the other but if you have a goal they will get you there as long as you put in the effort and dedication, my goal for now is to get to a comparable level as I previously was and I know I will & I spoke to Travis about competing (when I'm back to how I was) and he is fully supportive. You get world class training, and really some of the nicest guys I've had the privilege to train with and learn from, I'm glad I didn't let my fears keep me from entering that door. If you are looking for a great place to train & you live in New England I highly recommend coming here.
