“I had just moved to the area and was looking for a new gym back in October. Boston Underground was the perfect fit. The strength camps work best for my goals, and the coaches have all been amazing. They make you feel like part of the family from the start and provide individual attention to help you perfect your movements and get the most out of your workout.”

“I am not the most athletic guy, but I've been coming here for almost two months to do the "Punches and Crunches" class. What I have found is a gym full of supportive, passionate, and motivated people who want everyone around them to succeed. You should give this place a shot, even if the idea of a boxing gym is intimidating for you!”

“This is my 3rd CrossFit community (to accommodate my work locations) and I couldn’t be happier to have landed here. The staff truly goes out of their way, during and outside of class, to deliver top-notch service and get to know their clients. Nothing makes me more proud than seeing the community embrace a new first-time member, then watching that member succeed and learn to love all they are capable of. Special shout out to coaches Steven and Scott for your unwavering support and passion for making great experiences.”

“OTF WALTHAM gives the best workout you can get in 1hour! The music playlists they create is over the top! An hour just flies by...The coaches, especially Jules and Helen, are just remarkable with such dedication and interest in each and every member of their class. I so look forward to the hour of fun and a highly satisfying workout each time. (And did i mention the awesome music?)”

“Membership at Flight is worth its weight in gold. The staff are knowledgeable, friendly, & work hard to provide individualized attention for everyone in the gym. I am a local rugby player and the fitness programs I received were tailored to my on and off field goals and developed as I did throughout the season: injury prevention and recovery, increased flexibility, speed work, etc.Great community, great coaches, great space. Get to Flight!”

“Dropped into CFN twice this week and have nothing but positive feelings about this place. Classic CrossFit class format with stretching, strength, and a metcon. Worked with coaches Alayna and Jack. Both couldn’t be more friendly and attentive to the athletes/community. Witnessed them assist adapt the workouts for newer athletes as well as critique the more seasoned gym-goers. CFN also has a very welcoming community which always enhances the overall fitness experience. Plenty of room, clean facility, and amazing people. Would strongly recommend for anyone living in the area looking for fun yet challenging workouts or dropping in for a couple of days. Thanks for having me, I’ll be back.”

“I’ve searched for months looking for the right personal trainer. If you’re like me, you wanted someone caring, understanding and will push you to no end. I joined the thumbtack app and came across Slava’s page. Guys! This is the BEST decision I have ever made for my fitness journey. I started this journey at 204.6 lbs. I’m down 14.5 lbs. today. Slava and Anna are the best to do it. They care not just for your exercise routine, but also what you’re consuming daily. I can send a txt when I’m down and out and they have snapped me out of it. They introduced me to portion containers and different protein shakes for muscle recovery. They check on me constantly and gives the best advice. I never knew working out and preparing meals weekly will be so much fun, but when you’re finally getting results, and are consistent with the help of push and motivation from people like Slava and Anna, there’s no way you could fail. I’m doing exercises that I NEVER thought I could do. I’m so blessed to have such an amazing team in my corner cheering me on in my health journey. Anna, Slava thank you so much for being apart of this with me and changing my perspective on health and wellness for the better.????”

“Kevin is the best! After suffering a torn TFL muscle while training for the Boston Marathon, I was devastated and unsure if I'd be able to run. However, thanks to Kevin, not only did I recover in time, but I also felt stronger and more confident than ever before.What truly impressed me was Kevin's holistic approach to my recovery. He took the time to listen to my concerns and thoroughly evaluate my injury. Not only did he focus on developing a personalized strengthening and rehab program, but he also took the time to educate me on proper nutrition and hydration strategies for endurance running.His expertise, professionalism, and genuine care for his patients make him an invaluable asset to any runner in need of physical therapy.”

“Great gym, good facilities, the upgrades and additional equipment added recently have made a big difference in wait times. When equipment breaks, I see a service call placed almost immediately with the equipment often being fixed rapidly. Front staff are extremely friendly and welcoming, as are the janitorial staff in the locker rooms. I have not worked with any of the trainers but they all seem knowledgeable. Overall the best higher end gym in the area for the price.The only few requests I would have is a Lateral raise machine should be on the shopping list, as well as a “Mag-Grip” attachment for the lat pull down.”
