“As someone who is not a gym gal, orangetheory has been the perfect place for me to become one. I joined because i was going on vacation and my coworker recommended orangetheory to me. I love the accountability aspect you are held to. I paid for a planet fitness membership for two years and never stepped foot inside, at orangetheory if you do not cancel your class within 8 hours you owe a cancellation fee. The amount of times i dread getting up and out of bed but only have 2 hours before class starts, you best believe im getting up and going and afterwards i never regret moving my body. Now i have a routine down, the coaches are so patient and take time explaining when i am lost, i never thought id actually enjoy the gym but i love orangetheory”

“I joined F45 South Edison Feb this year and absolutely love it. I needed a challenging, motivating, group-style workout regimen and a sense of accountability so i show up whether i feel like it or not, and f45 totally provides this. The coaches are super knowledgeable and supportive during the entire workout. Coach Gabe and rly all the coaches are amazing - they stay engaged and give you tips on improving form and technique. I love how it's a different combination of workouts each time. The group atmosphere of like-minded people, detailed coaching, and pump-up music always pushes you to go hard and get better. Really great place.”

“I've been actively lifting and working out for over 12 years, but outgrew commercial gyms and have striving to find a gym that has much more of a community focus these last few years - and the Garage IS that gym. This place has all the equipment and space you could ever imagine, 24/7 access, always clean and offers one of my personal favorites, which is the chance blast your own music over the communal iPad (I'm the one always blasting metal ;)).

Everyone that goes here is down to earth, friendly and looking to engage with the gym goers - not to mention regularly holding events to meet up together, work out together, run together, get coffee, etc. Everyone shares the same amount of respect for the gym and one another, which is rare treat to find. Kieran has put together a killer environment for those who are passionate about their fitness and community. I couldn't recommend the Garage enough to anyone looking to take their fitness to the next level.”

“Have been coming to Outerbridge Athletics for over 10 years. John and the gyms vibes have always been top notch. The workout programming is phenomenal and never gets old. It is truly a family affair as now both of my daughters attend the gym with my wife and I. They are excited every time they walk in the door. Have made many great friends who have become like family but always welcomes new members.”

“Absolutely love Orangetheory! The coaches are motivating, the workouts are challenging in the best way, and the energy in the studio keeps me coming back. Every class pushes me to do better than the last 🧡”

“Joining Orangetheory has been one of the best decisions I’ve made for myself. I’ve been a member since February 2026, and since then I’ve lost 20 lbs while my stamina and endurance have gone through the roof. I workout Tuesday through Thursday in Emma’s classes and have been absolutely crushing it under the orange lights ever since. 🍊🔥

A huge part of that is because of the absolute BEST trainer, Emma. She walks through those doors with the warmest, kindest smile and instantly makes you feel comfortable and capable. She corrects your form, cheers you on, and pushes you to accomplish things you truly never thought you could do.

I’m so thankful for Emma and the entire OTF Garwood team for helping me grow into someone I never imagined I could become. I’m out here running 5K & 10Ks now, and that is something I NEVER would’ve said before joining. Even Jonathan at the front desk made the sign-up process so welcoming and easy from day one :)

Fitness can be intimidating, but this studio brings such a genuine warmth and support that makes you want to keep showing up. Forever grateful for this community! 🧡”

“Been going to Orange in Millburn for almost 8 months now, wanted some time to pass before I left a review. So far the staff has been super helpful whenever hiccups happen; they’re super accommodating. As far as the coaches, no one has really been superb to me , except a visitor coach Emma. Her energy and coaching skills are amazing. Very personable and feels like she actually cares. A lot of the coaches direct the class but don’t really interact with anyone. They barely fix any form or engage - it’s just giving out directions basically (Karlea, Liam, Elena). Had a few classes with Joe and he was engaging as well. Gina has a great playlist, is pretty cool, will always push you to lift heavier, and does fix form, but she acts very comfortable w her job and has an issue talking to ppl with respect sometimes. There have been a couple classes where she’s been rude on the mic unnecessarily when literally majority of the room are her seniors. We’re not kids. Have some respect. You don’t have to be rude to demand respect. It was a bit of a turn off each time. So I just feel like there’s some entitlement there that’s gone unchecked. Other than that the workouts are very effective and I’ve seen a difference for sure. May visit the Garwood location more since I’ve heard great things there.”

“My happy place, not just a gym a community & safe place!! No matter what your level of fitness or injury there is something for everyone. People come in looking for a gym, find their people & stay for yrs. Tim & Erin are not only business owners their all around incredible people!! And the coach’s are just fabulous!! They care & want to push you but safely. I can’t say enough about 908, try it and you’ll never want to leave.”

“I’ve been a member here for just over a year and am ecstatic to have found this place. I’ve seen large improvements to my general health and strength. The classes are welcoming and scalable to just about any level of fitness. No one expects you to be the strongest or do things that would put you at injury risk. There’s no judgement. Beyond all that, the community here is awesome, and everyone is supportive. I always look forward to my next workout.”

“I absolutely love Orange Theory! You could go to a different gym but you won't get the same intense workout that you would get from one hour with these amazing coaches. I'm hooked! Come try it just once for free and you'll see what I'm talking about.”

“Like so many things in life, you get out what you put into 908. But the crew here has created an environment that enables you to maximize your return on gym time.
