“Great place to get fit, even for those who do not imagine themselves to be the crossfit types! All the classes here are upbeat, intense, and honestly fun. Each day's workout is totally different which keeps things fresh. Justin and all the coaches are there to ensure you can do the workouts safely and effectively, always offering suggestions of how to scale down movements that are too complex or difficult (for now). Really diverse group of people here, all ages and fitness experience. This place is the best!”

“Burn Boot Camp has amazing motivating personal trainers. Each week they cycle through different classes, offer multiple camps per day and it's self paced in group setting. Membership includes child care services which is extremely helpful; making it very parent friendly. The owners/ staff are very pleasant, knowledgable and personaliable. I highly recommend.”

“I've had a great experience at Orangetheory Fitness West Windsor. The coaches and staff create an encouraging, motivating environment that makes it easier to stay consistent with workouts.
A special shout-out to Michael—his energy is incredible, and he brings enthusiasm to every class. He keeps members motivated, explains workouts clearly, and makes even the toughest sessions enjoyable.
I also want to recognize Greg at the front desk. He genuinely cares about the members, always greets everyone with a smile, and goes out of his way to help. It's clear that he takes pride in creating a welcoming atmosphere.
If you're looking for a gym with great coaching, supportive staff, and a positive community, Orangetheory West Windsor is a fantastic choice!”
“The coaches are amazing, the atmosphere is uplifting, and the benefits are incredible. Such a great place to grow stronger, stay motivated, and feel encouraged every step of the way! I Love SETS💯”
“My 6 year old had a great party, and I was so grateful not to have to do anything having just welcomed a second baby. Thank you to the staff at tumbles! She had a wonderful day.”

“I’ve been coming to this gym since the beginning of December. I have to say that this is the most welcoming and friendly gym I’ve ever been to. When I had questions about signing up Robyn the manager was super helpful and knowledgeable. She’s incredibly accommodating and I had something come up and she immediately fixed it without an issue. Bianca at the front desk is also so sweet. She’s there on the mornings I go and she’s a friendly face who is also very helpful and knowledgeable. The coaches are great and motivating and the classes are accessible with modifications if you let the coaches know ahead of time. They always check in with me to make sure I’m doing well. I have to say I highly recommend this gym.”
“Just finished my second month and I am definitely stronger. More importantly, I have cut 2 pounds of fat while adding muscle and I have dramatically increased flexibility. Classes are small and everyone is here to encourage each other while growing ourselves.”

“If you’re looking to add some peace, clarity, healing, mindfulness & calm to your day to day life, this is the place for you. Whether you want to work on breathing & meditation, build strength & lose a few inches or simply have a place to go for refuge from the chaos of life, the movement can provide all of this and more! The staff is warm, welcoming & kind (and extremely experienced & knowledgeable). You’re not just a face in a sea of people crammed into a classroom. You’re treated like a part of the community from the moment you walk in. Can’t recommend this place enough!”

“Very friendly and knowledgeable staff. They know their stuff ⭐️This is the place to go to when you want to feel better both physically and mentally.Beautiful and clean space.”
“I’ve worked out my entire life and have been a member of many gyms, but Orangetheory Fitness Princeton stands out.
The workout is comprehensive and a no-brainer. You walk in, and everything is mapped out for you. The coaches are not only motivational and personable, but also incredibly knowledgeable, bringing great energy to every single class. Shout out to Derek, Romeo, Jared, Sam, and Coach Boo. They know how to push you while keeping things safe, effective, and engaging. The staff is just as wonderful, welcoming, helpful, supportive, and genuinely kind.
What I love most is how the workout covers all aspects of movement and different training modalities. It’s effective whether you’re a young athlete pushing performance or someone simply committed to staying strong and healthy later in life. It’s structured, efficient, and it works. I've seen a lot of good strength and cardiovascular changes since I first started back in 2018.
I just show up, give my best, and in one hour, it’s done. Whether you’re a beginner or advanced, it meets you where you are and pushes you forward.
I’m so grateful to be part of this community. Thank you, OT Princeton. You rock.”

“This was an immensely positive experience. Workout classes are always tough, and Locomotion's HIIT circuit was. But the people in the gym were (1) locked in during the workouts, (2) inviting and encouraging during the breaks, and (3) and people stayed around for a little bit to chat after the workout ended. Whether they knew each other before or after, the experience felt non-judgmental, supportive and motivating. This was the epitome of a tremendous fitness group and community. I will definitely come back the next time I'm in Princeton, and I highly recommend others to give it a try as well.”

“Great Jim has everything you need if you want to get in and out quickly, I missed all the great conversations while I was on the elliptical. Great people working there that are serving in the military.”
“I booked a birthday party for my 5 year and I was a little skeptical because I had no idea on what they did for birthdays. My daughter wanted a unicorn themed party, and when I looked into it they did a themed birthday party, so I booked it!! Everything went smoothly. Ms Sam was so courteous and handled everything to a tee!! When I tell you she said they handle everything, they handled everything!! From the setup to the break down and they even put everything in bags for us and helped us bring everything to our car and helped us bring everything out of the car. My apologies to the other 2 staff that was there that also assisted her, I forgot their names, but also excellent service from the both of them.
They kept the kids entertained and definitely got some energy out! Would definitely recommend having another birthday there again!!”
“This is a very clean place! They have life fitness machines which are light years better than the matrix junk a lot have. It's bit of a ride for me but I will still go there when I can.”
“I love the non fluff gym. Though basic, it meets the needs of a serious workout. Though small, it has all the necessary equipment, which never gets too crowded. I have never waited for equipment. Friendly staff and clean environment and affordable.”
“Monica is well versed in the different schools of Yoga and is able to very effectively leverage the various schools of yoga to my needs. She emphasizes the need to breathe correctly as she gradually graduates you to more advanced poses. Would strongly recommend a personal class for the maximum benefit”
“A candid assessment from someone who was there nearly every day for 15+ years. If you believe you'll benefit from working out with a personal trainer, this is the place to be. Based on observation and conversation, the trainers are knowledgeable, dedicated, and diligent. It's also a good gym for anyone needing a pool, child care, classes, or other extras. The fitness center is well-managed, clean, overall a very good place.
However, if you are a veteran gym-goer and just want a place to throw around some weights and work out on machines, I would definitely recommend that you look elsewhere. There's generally one of each machine and quite frequently someone is sitting on it scrolling on their phone between sets. Of course, you can ask to work in and share the machine, which most people will do, albeit sometimes grudgingly. A few cranky souls actually refuse, apparently believing that machine belongs to them. Also, a trainer and client will be often be on a machine for 5 minutes or more, chatting between sets. I tried to avoid asking them to share because that is the trainer's source of income.
I am admittedly a bit of an obsessive nut when it comes to following what I deem good gym etiquette and would never sit on a machine for five seconds. So I wound up getting annoyed (and annoying others) a few times each workout. I finally moved to a gym that is larger (and cheaper) and has a few varieties of each machine. People still sit there and scroll - it is 2026, after all - but it's always easy to find another of the same machine. I miss the trainers and some of the fellow gym-goers at PFW, but the annoyance factor has been almost totally eliminated.
That's one person's view, for what it's worth.”
“New Member. Did a couple of Visits. 2 to the Gym over the Weekend. Older Fitness Equipment. Not Crowded. Left RWJ in Hamilton over that. Today I stopped at the Pool. 13 1/2Ft in one section. Made an Enjoyable Experience. 1 Per Lane. RWJ Hamilton 2-3 Adults per lane. Limited Hours for Pool. But a Reasonable Price.”
“I am actually a huge Pokemon go player and happen to live near here. I love the entire Princeton community and everyone who works and lives here is passionate about it”
“Amazing atmosphere and interior with real painting.
Art classes and intellectual poker.
It's just the past of the top of this iseberg of cultural life in Princeton)”

“The gym is pretty nice overall and has most of the equipment I want, but I wish it had a trap bar for deadlifts. If it is possible to get a trap bar, that would be greatly appreciated.”

“I’ve been coming here for about a year now and absolutely love this gym! They always great you and have positive attitudes! The equipment is so much better than most gyms I’ve been too, the locker rooms are always clean and the staff is just wonderful. Very family oriented and I am happy I joined!
My bf was traveling from afar and they were very accommodating to letting him have free passes.
The food is fantastic and I love their muffins!
I do wish they had a cold plunge but I still enjoy all the other amenities! This life time is great!”
“I like this gym location. The staff is friendly and welcoming. I work out in the mornings during the week and there aren’t many people. Clean facility. Recommend!”
“Good workout space with variety of equipment, a pool, basketball, badminton and pickleball courts. However, the pricing is slightly unreasonable. They kept on increasing membership fee. I started with about 39 per month and now it crept to 75 pm. This does not give access to all group trainings etc.”
