I had an amazing experience at The Fight Club at Muscle and Flow in Milton, MA. I took a boxing class with Edwin Frias for the first time, and it was incredible from start to finish. Edwin brings high energy, focus, and real technical knowledge to the class. He doesn’t just run you through combinations — he actually teaches you the fundamentals, breaks things down clearly, and makes sure you understand the “why” behind every movement. As a first-timer, I felt challenged but never overwhelmed. The workout was intense, empowering, and fun all at the same time. I walked out feeling stronger, more confident, and already looking forward to the next class. The atmosphere at Muscle and Flow is motivating and welcoming. You can tell there’s a strong community there, and The Fight Club brings a serious but supportive vibe that makes you want to level up. If you’re thinking about trying boxing — whether you’re new or experienced — I highly recommend taking a class with Edwin at The Fight Club.

I would absolutely recommend this gym! They have classes every day, ranging from yoga to boxing. I had the opportunity to take one almost each day, and I can genuinely say I enjoyed all of them. All of the coaches/trainers are very friendly, knowledgeable and take the time to teach you properly. Same for the staff!

I’ve had such a great experience at Muscle and Flow for the short time I’ve been there. From the moment you walk in, the staff makes you feel welcome. Everyone is incredibly friendly, approachable, and always willing to help — whether you have questions about equipment, need guidance on form, or just want some motivation. They genuinely care about members and it shows. The gym itself is also impressively clean. The equipment is well-maintained, the floors and workout areas are spotless, and you can tell that cleanliness is a top priority. It creates such a comfortable and positive environment to train in.

I can honestly say this is the best gym I've ever been a part of. Not only is the space clean and well-quipped, but the people here truly make the difference. From the front desk to the trainers, everyone is welcoming and makes you feel like you belong. I've been doing personal training with Andrew Stebbins here, and they've been a game-changer for me. My trainer really listens to my goals, pushes me just the right amount and makes each workout challenging but fun. I've learned proper form, built up confidence, and started seeing results I never thought I could achieve on my own. The atmosphere is supportive and motivating-there's no intimidation factor, just encouragement and good energy. It's become a place I actually look forward to going and that says a lot. If you're looking for a gym where you'll get personal attention, expert guidance, and a positive community, this is the place. Muscle and Flow also offers a wide variety of additional classes like yoga, and kick boxing. I highly recommend Muscle and Flow its a great gym, with easy parking and a great location.
