Roger has a wealth of knowledge regarding many a martial arts, and all of the advanced practitioners are very helpful and very respectful, as well. It's a great learning environment and a really great place to start out as a beginner; no hazing, no meat-head BS, everyone checks their ego at the door. If you're looking for a fun, productive and effective martial arts school, or if you're just looking to get in serious shape (serious, serious shape), definitely give WMMA a shot. After two weeks, you'll be looking at yourself in a whole new light.

Williamsburg MMA was recommended to me by a friend who just recently started boxing training. At 40…read moreyears old, I had always wanted to box but never took any initiative until this summer to do so. I signed up for the week trial at WMMA and worked with both Roger and Diego and felt immediately at home. Over the past 7 months, I have made Williamsburg MMA my second home. I started off going 2-3 times a week to boxing , and now find myself there 5 times a week taking every class available (Muay Thai, Jiu Jitsu, Grappling, and Wrestling with Michael). The staff there has had a profoundly positive influence on my physical and mental health. They also have fostered a warm community there, which makes it even easier to get myself out the door and on the mat each week.

As a young inexperienced unrefined woman, I often find it challenging to loosen up in a gym situation like this, as most of my prior experiences felt formidable, intimidating and frankly terrifying for me lol. I passed by this place walking by and was immediately drawn to the open airy aesthetic. It's not a gym that's closed in. Or in a dark sweaty basement. It's clean, open, inviting and unpretentious. As is the staff. These guys make you feel incredibly comfortable. Quick to answer questions, offer advice, and guide you thoughtfully. I like the vibe here a lot. was surprised how quickly I picked up things and got comfortable. Plan on coming back... nice this is in the area.

This review has to do with the administration of the school, which I have had an absolutely horrendous experience with, so much so that I feel the need to write a review to make other people aware of the way they have dealt with me - which is borderline immoral. At the start of this year I postponed my year long martial arts training (billed monthly) by 3 months because I was going to be out of the country. I got a written confirmation email from the school stating that they could honor this request and would not charge me while I was away. A couple weeks before I came back to New York, I had a seizure while still traveling, which also caused a shoulder dislocation while I was unconscious. Needless to say, I cannot practice martial arts for the foreseeable future. I requested to cancel the remainder of my one year training contract for medical reasons. NYMAA said they would not be able to do this without a medical note from a doctor. This is despite them telling me when I signed up initially that the year long training could be cancelled at any time - this is predatory business practice #1 - locking you into getting charged every month for a year, while telling you you can cancel anytime but not planning to honor that. I sent them a letter from my Doctor, clearly saying that after being evaluated I should not be participating in martial arts and should have my remaining months cancelled (they charge $207/month for JKD training). Not only did they refuse to acknowledge the letter because it was missing an official letterhead (something they neglected to mention they needed when first asking for the letter), but they also began asking me for proof of my travel, all of a sudden investigating the past, despite having agreed via email before I left to postpone my payments while I was away. I sent them a new letter with the requested letterhead from my doctor, as well as my travel itinerary, and then they went radio silent, despite repeated follow ups. In that time, I noticed that not only was I charged for the month of May, but there were also three attempted charges for the three months I had been away, trying to be retroactively billed to my card. Absolutely INSANE. I called, and upon speaking to someone in person it was clear that she didn't know that this had happened and was generally unaware of the new charges, but she did say that they still wouldn't accept my new letter, without giving a clear reason why. At this point this feels like a SCAM. I have provided everything asked, and they keep coming up with bullshit reasons why they can't cancel my membership, AND are trying to retroactively charge me for months that they agreed IN WRITING not to charge me for. No one can clearly or cohesively explain to me why any of this is happening. It's a shame that such a great school of martial arts is being run like so unscrupulously. At this point I've gotten my credit card company involved, but the whole situation been a nightmare. Forget about the lack of basic decency on display; treating someone who has medical proof of a seizure like an investigation subject. Sign up for a membership with these guys at your own risk. All I can say is be 100% sure you plan on using your membership and won't need to alter or cancel it for any reason because this company has demonstrated that they have no moral issue with charging your card on file however they see fit. Absolutely pathetic business practices.

In lieu of the standard "fitness class", Movement Brooklyn focuses on incorporating movements from a variety of disciplines to help folks more efficiently and without pain. We can't wait to incorporate more movement classes into our workout routine! Kyle and Alexa have systemized their approach to teaching proper movement; the cross functional aspect of the curriculum makes every class unique yet applicable to one another. The best part about the classes is that anyone can join and you don't have to be a fitness guru to have an awesome time. If you're looking to feel better physically and mentally, I highly recommend trying Movement Brooklyn!

All the coaches are knowledgeable, talented, and respectful - but I need to shout out a few wonderful humans in particular (the ones I've taken the most consistent classes with). Hannah - kettlebell MASTER. Makes classes fun, functional, approachable, and just the right amount of hard. I've seen my upper body strength improve greatly and learned a ton of cool moves with kettlebells I wouldn't ever have expected. Xtina - remarkably kind and encouraging. Creates a fun and challenging HIIT class that's never boring and is always a full body workout (plus fun playlists). Plus, the coaches for all athletic/strength training coordinate classes to rotate the focus each month so 1. You can see progress and 2. You have something new to look forward to each month. Bri - creates such a warm atmosphere with a focus on wellness and athleticism in creative ways. Has an eye for detail that makes the most basic of moves more challenging in the best way possible. Nhi - a Muay Thai powerhouse who coaches both coed and women/nonbinary classes. I appreciate Nhi's encouraging approach and ability to point out small improvements in technique that make a big difference. This gym and its people are awesome, and if you needed more reason: some of the coaches and more longtime members bring their pups to the gym. So yeah, it's great.

He has incredible professional boxing experience and a lot of experience training professional boxers, but he is able to adjust his training to everyone's level. I am nearly 70 years old and describe myself as a recreational boxer at the beginning/intermediate level, and Athanasios was able to structure my training sessions to be challenging, but achievable. His sessions were a fantastic cardio workout! My boxing skills improved a great deal while I trained with him weekly for more than one year. Sadly, Athanasios moved away to live in New York City so I can't train with him anymore, but if you have the opportunity to train with him, DO IT! No matter which level of boxing experience you are at, I guarantee that you will have fun, learn a lot, and have a great cardio workout with Athanasios.
