Fitness & Gyms in Waltham, MA

“I can’t say enough good things about this gym. From the moment you walk in, you can feel the energy and the level of care that goes into everything here. The facility itself is top-tier clean, well-equipped, and set up in a way that actually pushes you to work hard and improve every single day. What really makes this place special, though, is the environment. Everyone is included, no matter your level. Whether you’re just starting out or already experienced, you’re treated with respect and pushed to grow by everyone. There’s no ego, just people trying to get better together. The camaraderie here is something you don’t find anywhere. The fighters build real relationships like a family , something that is unheard of in this sport. You’re not just training next to people, you’re going through the grind together, supporting each other, and holding each other accountable.
And the coaches? Honestly, they’re on another level. Matthew Nolan and Mark Nolan lead the gym in a way that sets the standard every day, and coaches like KB, Paige, Alex and Paul bring that same intensity and care every day. They’re not just great coaches, they’re people you genuinely look up to. They push you, believe in you, and want to see you succeed both in and out of the gym. If you’re serious about boxing or even just looking to challenge yourself, this is the place to be. 5 stars isn’t enough. Without this place, I would not be who I am today, not only as a fighter but as a human being as well.”

“Flight Performance and Fitness was my first real strength training experience, and I couldn’t have asked for a better introduction. My experience was incredibly rewarding! From day one, all of the trainers knew my name, helped me through my workouts, and made sure I was using proper form. Dan Stone worked closely with me, took my goals seriously, and built a program that felt truly personalized. Magnus and Bryce were also always available to help and encourage me. I was honestly surprised by how much progress I made in only six weeks. Beyond the training itself, the gym has a fun, supportive atmosphere, with friendly coaches and a welcoming community. Highly recommend!”

“I love being at spin classes here! Pre-pandemic, I was in a 5-morning-a-week routine at my workplace gym with a fun instructor and a great little crew. Coming to FireCycle for morning classes has revived my energy and enthusiasm for getting out of bed each day! I didn't realize how much I truly missed this kind of great cardio workout. It's a welcoming place with great instructors and it is CLEAN...I mean CLEAN. It is cleaner than pretty much anywhere in my house and for sure any gym or even restaurant I've ever been to! It's so easy to just drop in, hop on a bike with your water bottle, and get into whatever dance music or mashup the instructor has cued up. They provide towels and even a shower (did I mention how clean this place is?). Lots of street parking available for early morning classes. Come join the fun and get into a great healthy new routine!”

“I've been member since August 2024 and can't recommend this gym enough. I have a background in weight lifting but I could never stay consistent until I started working out here. What was great for someone like me was that I didn't need to guess or find some questionable routine on instagram to follow: the trainers make tailored programs targeted at your goals and build around any limitations or past injuries you may have. As a bonus they are also very easy going and supportive which is great for someone like me who had gym commitment issues in the past. There also isn't any pressure while you're in the weight room: there's plenty of equipment so rarely any need to work in and with the small groups you get plenty of one on one time if needed. For someone like me who just needed a little extra push, its been perfect. I've seen great results and plan to continue coming for as long as I live around Waltham. Come hang out! We're pretty fun”

“I've been a member at TILT for almost 2 years now but I have been going to the location in Waltham for about 4 months now and I absolutely love it! All the coaches are great but Cam especially is the best coach I have ever had! He always pushes me to do more, always so encouraging and keeps the class fun! It really makes me look forward to coming to class. I also love the community that we have in the gym where everyone wants to see each other succeed.”

“My home studio is in Bedford, NH. Today I had business down in The Watch City, and i wanted to make sure I could work in a class around lunch time. The location was 2 miles from where me meetings were so it was easy to make the Noon class. My first visit to OTF Waltham and I hope to be back again!”

“This is so much more than a gym! You’re joining a village of people who truly care about YOU. CFN is where to be if you want to mentally and physically feel good. Gil genuinely gets to know each member and helps you achieve whatever goals you have in mind. You’ll wake up wanting to go each day. It’s for everyone regardless of your age or physical abilities. Not to be dramatic, but it’s life changing. Come see!”

“Highly recommend Slava and Anna if you’re new to strength trading or like me looking to jump back in! I was able to start with body composition scan which was great for motivation! I had all the equipment at home but needed inspiration. Anna is amazing and I began looking forward to my workouts and progress. I booked a 10 week package and didn’t miss one workout. Anna came to my house and utilized all my existing equipment. Hardest part for me was coming up with a routine. Anna was able to do that for me! They are so friendly and honesty made working out FUN again. If you’re not sure where to begin, start here! I’m so glad I did!!!”

“Btone Waltham is my happy place! I love the instructors, the type of workout, and the friends I have made in the studio. The space is clean, the instructors are friendly and helpful, and classes fly by. The last three classes I have taken have been so challenging (in the best way) that my friend and I look up and there are only 5 minutes left in class. If you have not already, check out Btone Waltham, I promise you will not be disappointed!”

“Champion has helped me target a ton of weaknesses I was kind of glossing over in my past training programs. I feel so supported by Greg, Eric, Bobby, Mike and Kylie. It is a great environment to iteratively fail in, because it has made me a better and more resilient athlete.”

“Some of the cleanest restrooms I’ve ever been in. Usually that’s the worst. The gym is nice as well. We came with a visiting team for a basketball game and were treated great by everyone there. Class was definitely on show.”

“Really nice, solid gym with recent upgrades. Has gotten crowded in 2025. Did they overdo the membership in January? Hope it will calm down. Has gotten harder to find free equipment lately.

Update 2026. Like the gym a lot. But dang it’s so busy after work and on weekends. Maybe pause the new memeberships?”

“This gym is great, and I wish I could go more. I have been to other ymca's that were really sub-par, but this gym is clean, easy to navigate, and has a large variety of options. Also the sauna is great and when I take my son too the family restroom it is very safe and clean.

I stopped my membership for awhile and had to come back because it is a nice gym and during the winter it's a must. I edited to a 5 star because it is pricey but you get what you pay for. I just wish the child watch was open for people who are working a 8-5 job full time.”

“An excellent location for your basic workout needs.
This franchised location has been located at the back of the industrial park for over 20 years. There is plenty of parking in the complex, along with a bike rack, handicapped accessories parking and ramp to the entrance. They have all the standard equipment, the 30-minute circuit, a weight lifting area, a designated stretching area, and the massage and relaxing area for PF Black Card members only. Most of the equipment is older and they have been trying to get in newer machines for years, but are facing issues from corporate. Whenever I've interacted with staff, they have been friendly and helpful.
A good place for a workout as long as you're not looking for all the bells and whistles.”
