“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”

“The black card is a fantastic value for a married couple!! We found the gym in plainsboro to be fantastic!! Very clean location, great locker area and very well maintained machines.”

“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.”

“It's not just a gym, they are friends and family. They easily adjust work outs to your ability and make it fun! My sister and I are founding members and have been able to break our PR many times. I don't think we would have done that any place else. Instead of losing muscle as we age, we have gained it!”

“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!”

“I have so much love for this gym and the whole staff! The classes are great, the fitness equipment is awesome and the support and motivation is unmatched in comparison to any gym I have ever been to. Larissa in at the front desk is incredible - she care about the members joining, their input, and making sure the membership you get is the best one to help you meet your personal fitness goals! The Muay Thai classes are incredible and I can't wait to get back to it once I heal from my back injury. B52 Muay Thai - Love you, fam!”

“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.”

“As a women’s health and wellness club at Rutgers, New Brunswick, we’re always looking for workouts that truly challenge us, and CKO absolutely delivers!

From the moment we walk in, the energy is unmatched. Coach Kevin was motivating, knowledgeable, and genuinely invested in helping everyone feel strong and confident. Every workout is different, which keeps things exciting and pushes us out of our comfort zones in the best way possible.

Our members LOVE the burn 🔥It’s the perfect balance of challenging and fun, and the supportive atmosphere makes it easy for everyone—no matter their fitness level—to feel welcome.

CKO has quickly become one of our favorite ways to train together, bond as a club, and prioritize both physical and mental wellness. Highly recommend to any student organization or group looking to level up their fitness game!”

“Amazing Place great people

Highly recommended ????”

“My husband and I have been going here for over a year now and it’s been an amazing experience! We have progressed significantly since we started. We feel stronger and much more active! The staff have been great and very supportive. Thank you!”

“CrossFit Jungle Gym is an awesome facility with phenomenal coaches and a very welcoming community. I really enjoyed dropping in and definitely recommend this gym to anyone looking for a place to train.”

“I love love love this gym. I especially love the classes. My favorite classes are Boxing, Zumba and Step. The instructors are full of energy, very motivating and encouraging. And the owners and employees are great.”

“I absolutely love this gym. Nick at the front desk is so friendly very helpful and always looking out for the members. The trainers here are amazing as well. Alvin really listens to what the client needs and goes above and beyond to make sure results are met. Never looking to change my gym.”

“I’ve been training here for almost 2 years now, and it’s truly been one of the best decisions I’ve ever made. I had never done CrossFit or lifted weights before joining, so I was definitely a bit nervous at first — but the community here is incredibly welcoming and inclusive, and all the coaches are truly amazing. A special shoutout to Coach Joe, who was so attentive and supportive when everything was new and unfamiliar to me — his guidance really helped me build confidence and improve safely.

The programming is excellent — always challenging but adaptable, and it keeps things interesting. They also offer a running class, which completely transformed my relationship with running. Huge cheer for Coach Nora for helping me fix my form and actually start enjoying running (something I never thought I'd say!)”

“I vehemently disagree with the sentiment shared below. Everything mentioned is subjective, and thus, should not be taken literally. I have been a member of this gym for ~4 years and have had the opposite feeling. The owners are courteous, caring, and passionate. For example, one time, I needed a specific cable attachment. The next time I came in, it was ordered. I never asked for it, but me mentioning it in passing was taken seriously enough for them to order this item.

Moreover, the badge not working is not a gym system issue. The member likely had a faulty badge. It is his responsibility to approach the owners to ask for a new one. I have entered the gym as late as 2 am and have had no issues. When I forgot my badge, the phone was answered immediately and I was giving step by step instructions to enter.

Finally, this gym is promoted as a warehouse style, hardcore gym. I along with my friends appreciate the hot weather because it allows us to get a better pump/workout, and allows us to build more resilience. The one fan is enormous covering almost 3/4th of the ceilings surface area and provides more than enough ventilation.

Diesel is the best gym i have been to, and has an excellent community - which is due to the passion, hard-work, and love the owners put into it.”

“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.”

“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 have had a very pleasant and encouraging experience at this Somerset center of Fitness Factory starting with Mason , the young receptionist’s welcoming smile to The amazing talented physical trainer Luis Rodriguez .
Luis has had vast expensive training himself as a body builder as well as motivating others to be in their best form possible.
He is always punctual, adjusting to clients schedules, and an expert at in use of different machines, to strengthen the muscles, without aggravating the joints.”

“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.”

“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.”

“Gym is not clean and the sanitizer is water. Every time I leave feeling dirty no matter how much I use on the equipment. Also the GM is miserable, mean to customers and will probably call me to yell at me about this review. The only reason I keep my membership is because of Adnan the yoga instructor who is amazing.”

“I love this place... great classes with amazing teachers... daily meditations... the atmosphere and the people who gather are good company, too... the special workshops and courses... Aerial Yoga... and almost everything is free just asking for donations to help keep it happening... lovely”

“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”

“I've been a member of this gym for quite some time, over 2 years, and I wanted to take a moment to recognize the outstanding job Marie has done since becoming manager.

The difference over the past couple of months has been remarkable. The gym is noticeably cleaner, more organized, and much better maintained than before. Weights, attachments, and equipment are consistently put back where they belong, and the overall environment feels more professional and welcoming.

One of the biggest improvements has been Marie's efforts to ensure equipment is used respectfully, especially during busy hours. This is not a huge gym, and when benches, machines, or the Smith machine are occupied by people sitting on their phones for extended periods, it can create long waits for everyone else. Marie has addressed this issue in a fair and professional way by posting reminders throughout the gym and politely encouraging members to be mindful of their time when others are waiting. As someone who works out regularly, I can honestly say it has made a significant difference in the overall experience.

Beyond that, the day-to-day management has been excellent. The gym is consistently stocked with toilet paper, disinfectant spray, and cleaning wipes, and it’s clear that attention is being paid to the details. Marie also makes an effort to learn members' names, greet people personally, and create a friendly atmosphere that makes everyone feel welcome.

Good management can completely change the culture of a gym, and Marie has done exactly that. The facility is cleaner, more efficient, and more enjoyable because of her leadership. She deserves recognition for the hard work and dedication she brings every day.”

“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)”

“My butt started to itch after going to the pool. Doctor told me they need to cut off my butt cheeks. Overall, gym is great, pool is great, recommend 100%. thumbs up ??”
