Fitness & Gyms near West Newton, MA

“I held onto my gift card for my first few sessions for two years. I’m so glad I finally got started, I LOVE it! Michael turns each week into another set of achievements to get you totally addicted to the progress. My clothes fit better, I move differently, and I see my muscles building even after only two months. The flexibility with switching times, even last minute, has worked out just fine.

Others here say they wish they started earlier, I’m so glad I started now. Now is the time.”

“I’ve been going to Barre3 in Brookline for a little over 2 years now, and it’s the best part of my day every single day. The front desk staff and instructors are incredibly kind and welcoming, and I always feel safe and supported in my classes. I’ve grown so much stronger and can feel a significant difference in my life since going to barre. I love it!! <3”

“Poli has been wonderful with my parents. Her friendliness and energy make sessions enjoyable, and she’s helped them noticeably improve their mobility. We’re really grateful for her.”

“Amazing CrossFit studio for anyone who wants to challenge themselves! The schedule is incredibly convenient for a working parent. Every class is different and never boring. Instead, it’s highly motivating because you are training alongside dedicated people who show up religiously. The instructors are attentive - they correct your form and carefully guide you through new movements. I had never done high-intensity strength training before, and now I can't imagine my life without it! I also like the gym's minimalist design without unnecessary glamour - it is very cozy and makes you focus on yourself and surviving that hour!”

“I am a nanny for a 3 and 1 year old who both love coming to My Gym Newton!! The classes are always so much fun for them and the coaches are amazing. Leila, Fiona, Frey, Marcus and Rachel are all great! They are always super engaging and keep the kids entertained all class long. We could not recommend My Gym Newton more!!”

“Joining Sweat Fixx was the best decision I’ve made!! Highly recommend anyone who’s looking for a new gym to try it out, you won’t regret it and I promise you’ll be hooked!”

“I signed up at Burn Needham through a 28-day challenge special. At my first class I was astonished how many people I met there attend camps 5-6 times a week. One month into it I am now one of those daily participants and I love it. The community and motivation from trainers and other campers is addictive. I feel challenged and simultaneously supported. Thanks Burn!”

“this is a great place. I‘m glad I started with D1. I have taken 10 classes so far. I already fell that much stronger than before. It‘s very structured class focusing on performance, strengthening, and core. The class breaks down to small , tangible tasks, not overwhelming at all. This is a small family business that doesn’t Have the corporation and chain store Atmosphere. I used to train with orange theory. They have the standardized protocol for classes, With videos guide you through the training process. I felt like i was a chicken on manufacturer line. At D1, The coach will design the class, it feels like personal trainer in a group setting. The equipment is excellent. After each class, I simply feel good. It is not too hard, Making me not wanting to go. I just focus on showing up. I always get very good workout. I feel that this is something that I can stick to. It is not Like some gyms That I would sign up and quit or not going.”

“Almost three years ago, I tried out CrossFit on a whim here. Rackhouse has been a great experience from day one. The owners, Mia and Susan, put a ton of effort into keeping the gym improving. New equipment, new weights, and expanded programming. They do it all. The coaches care and will support you and help you achieve your goals no matter where you are in your fitness journey.”

“Reimagym is more than just a gym. It’s a community of radiant people - some just also happen to be wonderfully knowledgeable coaches and friendly staff!

Pre-Reimagym, I was struggling to find a routine and community again after having moved. Other gyms didn't seem to offer what I was looking for, or communicate using inclusive language that made me feel sure or safe.

My first introduction to Reimagym was through comments on an FB post, and right off the bat, the vibe was.. brighter. More inviting. People spoke highly of it from a place of gratitude and love. After visiting the website and doing an in-person trial, I was reassured to continue with a membership by the inclusive and supportive language and the kindness I was met with! Every single person, coaches and members alike, radiates inclusivity and support.

I am so so so grateful to have been led to Reimagym. I feel so much better and stronger having a routine again - Even when I don't want to go to the gym, I still go and am *always* glad that I went. Not only for the great workouts, but also to see the lovely people that find themselves there as well. It's hard to feel lonely when you're surrounded by people who are rooting for you!!

Thank you Reimagym ❤️”

“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.”

“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!”

“Romel is a regular, hardworking guy. I've been training with him for a few months now and I am seeing and feeling the progress. The space is great, the location is ideal, and the hours are expansive: Romel is in that gym _all the time_.

Romel has clients in all kinds of situations and he can tailor the workout for you. He can meet you wherever you are, and push you up to the next level.”

“I started my training with Julie and Daniel at Activate Fitness a month ago and I’m beyond thrilled with their professionalism, program, and facility. After many years of a sedentary lifestyle and ailments, I was very nervous about starting my journey back to health and Activate Fitness turned out to be inviting, motivating, and the trainers are invested in my progress. Semi private sessions and tailored nutritional plans have kept me confident in my consistency and proud of my results. There is a warm sense of camaraderie amongst the patrons and the atmosphere is always energizing! Julie and Daniel expertly created a whole health mind body experience and couldn’t be nicer!”

“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!”

“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've been a barre3 member for years, and it remains one of the best decisions I've ever made. Every instructor brings exceptional energy and expertise, making each workout both effective and enjoyable. What truly sets this studio apart, though, is the community — from the welcoming staff to the incredible members, you feel at home from the moment you walk in. Needham is lucky to have such a gem.”

“We’ve been here 3 times for different pieces of exercise equipment (elliptical, treadmill, and now Stairmaster) over a few years and Dave has always taken really good care of us each time. Happy to make the 40+ min drive to this location for our home fitness needs.”

“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”

“Visiting Boston this weekend and had a great Inferno class with Coach Tyler! Helpful and encouraging! When I am back in Boston I will make sure to go to this studio! (-Renee from Charlotte)”

“I have always enjoyed the F45 model, however the Medford location has a wonderful, enthusiastic, well educated group of coaches that makes coming to the gym a great experience!”

“I've tried just about every fitness program over the years—CrossFit, traditional weightlifting, running, cycling, and group classes—but Power Rowing with Bryan Fuller has been the most effective and sustainable workout I've ever found.

The workouts are incredibly efficient, combining strength and cardio in a way that delivers real results without beating up my body. The low-impact nature of rowing means I can train consistently, recover quickly, and still push myself every session.

Bryan is an outstanding coach, but he's also just a genuinely great person to spend an hour with. He's knowledgeable, encouraging, and has a fantastic sense of humor that keeps the classes light and fun, even when everyone is working hard. He knows exactly when to push you and when to make the room laugh, creating an atmosphere that's motivating without ever feeling intimidating. It's a big part of why so many people keep coming back.

The results speak for themselves: I'm in the best shape I've been in for years and have lost about 15 pounds, all while feeling stronger, healthier, and with far fewer aches and pains than I experienced with higher-impact workouts.

If you're looking for a workout that's efficient, effective, low-impact, and genuinely enjoyable, I can't recommend Power Rowing and Bryan Fuller highly enough.”

“Club 600 has a friendly community atmosphere and extremely dedicated staff. I highly recommend my trainer, Gabriella, who I have been strength training with for > a year. Gabriella balances support & motivation with well planned training programs to ensure that I continue to progress without hurting myself or getting bored.”

“After years of working out on my own, I knew I needed a change. My routine was no longer delivering the results I wanted, and I realized I needed some guidance and accountability. From my first conversation with Ray, I was welcomed with encouragement, support, and a genuine commitment to helping me succeed.
The trainers are knowledgeable, motivating, and truly invested in their clients’ progress. The gym itself is modern, clean, and well-equipped, creating an environment where you actually look forward to showing up. The group classes are challenging, effective, and surprisingly fun.
Most importantly, RayFit has helped me achieve results that I wasn’t able to achieve on my own. It’s been a life-changing experience, and I feel stronger, healthier, and more confident than I have in years.
My only regret is that I didn’t sign up sooner.”

“Stop searching. This place has and does it all. Had the pleasure of working with Johnny Loreti. Top flight experience for this recent CA transplant. All the best equipment and 5* service. Above and beyond the diagnostics to explain what everything means and how best to utilize these metrics to drive outsized returns. 💪😊”

“Invictus Boston - Fenway has an amazing community of people that keep you in the game and give you a reason to stay motivated. The coaches have a shocking amount of patience and I am so happy they did not give up on me in the few days I dropped in.

I never thought I would enjoy any workout with how cold it is in Boston. Just getting out from the hotel to wait for the Lyft and get to gym was a struggle but just because you’re in vacation doesn’t mean we forget about it our health first.

Great facility, fantastic workout planning, top notch spot. If you were looking for a way to change your life - drop everything and go to Invictus Boston - Fenway right now!

HIGHLY RECOMMENDED!”

“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!”

“Thorough attention to all the right details. Committed to creating a strong foundation to prevent injury and imbalances so they can gradually improve strength and speed. Both my 12-yr old son and I are now training with Joe and Trevor.”

“We are so grateful for Inclusive Fitness (West Roxbury) and the welcoming, supportive environment they provide for neurodivergent individuals. Since joining IF, our son looks forward to every session. He especially enjoys working with Coach Kristin who connects with him in a way that builds both confidence and trust. The focus on building strength for activities of daily living has made a meaningful difference, and we are seeing that progress carry over into everyday life. Inclusive Fitness has been an incredibly positive experience for our family.”

“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.”
