When I first wandered into Hard Knocks for my introduction session with Bill, I was hesitant and…read morenervous as I had never played sports, let alone train Muay Thai. The moment I walked in, I immediately felt welcomed. Bill asked me what my goals were and at the time, I had always been interested in trying kick boxing. I was provided with gloves and hand wraps to use and Coach Jake taught me how to wrap my hands. An hour and a bucket of sweat later, I signed up for a membership and decided to give Hard Knocks Muay Thai and MMA a try. Fast forward to almost 2 years later, this gym has become a huge part of my life in ways I couldn't have imagined. I did more than "try kick boxing". I met a group of extremely skilled and knowledgeable coaches, trainers, and fighters that have helped me take my fitness to the next level. I've begun to fall in love with a sport that pushes me to face my fears. The coaches and fighters in this gym are the epitome of discipline and hard work and it has truly been a privilege to learn Muay Thai with them by my side. There is always room for improvement and everyone is always looking out for you, to help you reach your full potential. My favorite part about Hard Knocks is the sense of family and I wouldn't want to train anywhere else! Book your free intro class now!

Awesome gym. Period…read more Bill and his staff are knowledgeable, professional and will put in the time to help you reach your goals. If you want to fight, they'll get you ready; if you want fitness, they'll get you in shape. After a few sessions, you'll be angry at all the time you wasted at your typical gym. The gym is fully equipped with a full size ring, heavy bags, pads, bands, weights and wall to wall full size mirrors. All of that for an affordable price - actually, it's the most affordable Muay Thai gym in the Boston area. Plus, they offer many other classes like Strength and Conditioning, No Gii BJJ and MMA. Seriously, why pay a similar price to mindlessly lift weights? Call Bill and schedule a training and learn something useful while getting into the best shape of your life.

If I could give zero stars I absolutely would!…read more I have never done this before.... But.... I am sooooo completely blown away by this customer service I had to! I am attaching a text thread that I had with the owner of the studio Bobby. I found him completely professional and insulting. If you like people like that you will love this guy. He has a business practice not to provide prices over the phone, you have to come into the studio. Ok totally fine, even though I explained that I needed it in order to budget and that coming in just for that info was inconvenient. He proceeded to tell me that if that was too inconvenient then it would probably be too inconvenient for me to take my child there 2 or 3 times a week. No - sorry sir, I am business owner and single parent who needs to manage my time and money wisely. If I went to every studio that I was interested in I would never have time to make a commitment. He then compared himself to jewelery stores and car dealerships... Which we all know, everyone hates dealing with these 2 types of businesses due to their shady business practices - though now a days - car dealerships have caught on and have their prices plastered all over their website... For what reason? Oh, to attract customers! Then knocked the name of a VERY reputable martial arts studio which has been in business for over 30 years! Take a look at this thread and then tell me if you want your child training under someone who is so combative, unprofessional and plain rude. He is the type of person I am trying to protect my child from. I mean he mocked the name of another studio to make his studio look better?! Who does that?! Then when I told him that this was going to be posted on Yelp and Google, he said people like me love to do that... No sir, I do not love to do that... It's my duty to inform those of extremely poor experiences so that I can save someone else from having a similar experience. If you look at another reviewer they also mention that he has shady business practices and would not honor the Groupon's that he has already sold! It's sad, I see he is a good instructor but integrity is everything. Also, isn't humility a characteristic that martial arts is supposed to teach? How can one learn humility from someone like this?
