“I love CrossFit Pepperell! It has been such a welcoming and supportive community since the moment I walked through the door. I’ve been to one CrossFit class years ago and was worried about joining; it’s not a sport I am familiar with and I’ve been very out of shape for four years. The coaches work with you and spend time explaining the workouts. I don’t feel silly asking questions and instead feel supported and uplifted. They do a great job of working with you, where you are at in your workouts. I appreciate that the warm ups often mimic the WOD and break down each exercise - it’s so helpful when learning! I’ve only been a part of this gym for a week, but I have learned SO much and feel so much stronger already! It’s an absolute blast and I can’t wait to see where my CrossFit journey takes me. Thank you CrossFit Pepperell!!! I am so glad I found this gym!”

“I highly recommend Mason if you are dealing with an injury that's interfering with your training. I've had recurring lower back and shoulder pain over the years. I met with Mason and he identified the movement patterns contributing to the pain, took the time to explain why I would be feeling pain, and created a warm-up program to address the root causes and allow me to move more freely in my workouts and in everyday life. Thanks Mason!”

“Just joined this gym a few months ago, and I’m in love with the place. It’s clean, well-organized and totally inviting. My workouts fly by with good music in the background, multiple tvs and excellent AC. I’ve yet to wait for a machine, and the app lets me know when there aren’t many people there so I can plan my visits well.
I’m working with trainer Nicole Cyker who’s helping increase my strength, endurance and cardio fitness. Besides my periodic doctor and dentist visits, this is the best thing I’ve ever done for my health.”
“OTF Concord is amazing! I’ve only been going for a few months but this studio has completely transformed my approach to fitness/working out. Every single coach is outstanding — high energy, friendly, attentive, motivating, and supportive. I feel my strongest, both mentally and physically. Thank you to Krysta, Julianne, Mallory, both Taylors, and all the staff at OTF Concord for helping us all be healthier!”
“Couldn’t recommend this place more! I joined knowing that I needed a consistent routine that I couldn’t keep on my own, and I am so glad that I did. It is such a great community in Westford with fantastic staff. You are always greeted with a smile here. I have gained so much confidence and strength these past several months and always leave with a great boost of energy for the day! Thank you OTF Westford!”

“*****2nd Review written in September 2025.. I successfully finished the AV1 in the Dolomites this summer. I am grateful to Jazzercise for adequately preparing me for this physically demanding hike. As someone who does not typically hike, like myself, having completed two successful 10-day intensive hiking trips in Europe, I strongly recommend Jazzercise to individuals who are preparing for hiking.
****1st Review written in February 2025. Since joining Jazzercise Acton Center in 2018, I've achieved a great level of physical fitness. Jazzercise has enabled me to tackle challenging hikes, including a 10-day Tour du Mont Blanc hike through France, Italy, and Switzerland in 2023. I'm looking forward to another 10-day hike in the Dolomites, Italy this summer. I'm grateful for the wonderful and supportive Jazzercise teachers and classmates. As always, l love to go to the classes.”

“Have been a member here at the gym for 4 months now and love it. I have tried several gyms in the past, big and small, and can say Stow is my top choice. Great variety of equipment and space, one payment so all members have access to everything, and never too busy to feel rushed to share space. Have referred one person here and encourage lots of friends to try it out!”

“We were visiting my mom in Acton and decided to give Anytime Fitness a try. We were greeted by the owner who was friendly and knowledgeable. The gym is excellent. It's very clean and has everything you need for a great workout. We prefer it to Planet Fitness. Now we have a gym to go to when visiting mom. Thomas & Larry”
“Could not get my 9 year old to leave after the trial class. She loved it SOO MUCH! I'm so glad that this business survived the pandemic. Kudos to them and our awesome community that goes out of their way to support small businesses.”
“Planet Fitness in Maynard is a convenient and well-maintained gym. The parking lot is large and shared with nearby stores and a supermarket, which makes it easy to run errands before or after a workout. The restrooms are clean and comfortable, and showers are available. Staff are generally okay, though not always the friendliest. The Black Card membership is definitely worth it and reasonably priced at around $25/month. Overall, a good gym — I recommend it!”

“I really like this place. It's very clean and it has everything. Shawn and the staff are great. If you don't want to be in a gym where it's overcrowded with people taking their tripods out and video taping themselves when you just want to get a set in. Westfit is your place. Check it out.”
“I went to an anime convention there, it was a nice and pretty place! the pool was a bit eh but everything else looked nice. so yeah that’s it, keep in mind I didn’t go into any hotel rooms I just visited the center!”
“I’ve been exercising at Title Littleton for 7 months and it’s been a fantastic experience. Most of the classes are boxing-focused with a couple of kickboxing sessions each week. Every class is instructor-led, starting with a quick warmup, followed by boxing, and finishing with a solid core workout. The coaches walk around to correct form, give encouragement, which makes a big difference.
I especially enjoy classes with Masha, Paola, and Shalton — they’re passionate, motivating, and push you to give your best. I’ve also been taking private “Mobility” sessions with Joleen, and she’s amazing. It’s an hour of stretching and floor exercises that has really improved my strength and flexibility.
I’ve gotten stronger, lost weight, and genuinely look forward to workouts here. If you don’t like the typical boring gym routine and want something effective, fun, and supportive, I definitely recommend Title Littleton.”
