Visiting from out of town- Had a great 90 minute with Elena. Large studio - 15 stations but
still nicely spaced on the floor, it didn’t feel crowded like in other studios. 3 stand alone bathrooms and 3 stand alone showers plus a prep space with some products, hair dryers, etc. lockers with programmable locks. Great space!

Emma was a great coach and seems like an even better person. I signed up wrong (reserved the bicycle but did not sign up for a treadmill) and so did not have a station for the rower and weight sections, but she helped accommodate me with grace and creativity. She saved my workout!

I have been going to Orange Theory in Warren for almost 2 years. I never imagined I could do the challenging workouts but I CAN! And I love it! The coaches are incredible! They are so upbeat and their energy pushes me! Their music is fabulous and I feel great when the workouts are done! It is a very positive environment Marcus & Spencer at the front are such happy faces and super professional! I highly, highly recommend this gym!

I joined 3 months ago & immediately after my trial class, I became a member. I enjoyed the class that much. Finding something that you like is really key & I've never liked working out. The classes are so much fun (hard at times), the coaches (Karlea & Gina) are great & the music is good. I also really like that each class is different & you're constantly competing against yourself.
Update: still love it. Coach Dan is motivational & his playlists always hit

My wife and I have been going to OTF Millburn since 2021. Most of my classes are with Coach Gina or Coach Karlea and I will say they are excellent. There is a real art to getting the classes right—Gina does a great job of providing informative instruction in a fun, positive way while also giving everyone a chance to get lost in the music. Karlea has the same talent for leading the class. I travel extensively for work and have tried other OTFs—the coaches elsewhere are good but either talk too much or too little or are just boring. It's not easy to get it right. I have yet to attend a another class in another part of the country with coaches as good as I have found at OTF Millburn. I might not look forward to every session but I'm always happier once I've done it.

“All right squad”- once you hear that be ready to suffer a bit. I’ve never been into Exercise Class sessions until I stumbled upon this fitness studio! I can’t say enough great things about Coach Gina at Orangetheory Millburn! From the moment you walk into her class, you can feel her energy. She strikes the perfect balance between motivating and encouraging, always pushing you to give your best while making sure your form is on point and you’re staying safe. In addition to this, her playlists are always on point!!

This place is the best monthly investment I have. Thanks to everyone and all the trainers for the great work! Keep it up!

I started my OTF journey back in 06/20 at the age of 60, and now I can keep up with guys 20-30 years younger . Didn’t know what to expect, but knew I wanted to take my workouts to the next level. Now, over 2 years later, It’s become a regular and important part of my life. I’m feel and look better. Had to buy a whole new wardrobe. The coaches are great and work with you to make each class enjoyable. But OTF is a community of likeminded people, who will encourage you to do your best. I like the fact that I can use any OTF, which comes in handy when traveling and you dot want to miss a class.
The Millburn NJ was very welcoming when I moved and the staff and coaches are fantastic. Gina slays so much, she should be arrested. Karlea keeps giving me more weight to keep me progressing
For anyone thinking about OTF, take a class and see how it goes. It changed how I looked at working out. I do it becomes I want too, not because I have too.
Thanks again OTF.

I cannot say enough great things about Orangetheory in Millburn! From the moment you walk in, the energy is infectious, and that’s thanks in huge part to the amazing team. First, a big shoutout to Dan, one of the best trainers I’ve ever worked with—his motivation, expertise, and genuine commitment to helping each member succeed make every class challenging but incredibly rewarding. Dan has a unique way of pushing you to your limits while making sure you feel supported and confident.

Also, a huge thank you to Fi at the front desk! Fi is always welcoming with a smile, remembers everyone’s name, and keeps everything running smoothly. Whether it’s helping with bookings or just brightening your day, Fi makes you feel like part of the family from the second you step in.

The Millburn studio is clean, well-organized, and has such a positive vibe—it’s truly the best place to get a killer workout and feel part of a great community. Highly recommend to anyone looking to level up their fitness journey!

I have been to OTF milburn for almost two years but have to say this is the worst OTF studio around the area. The coaches are very mean and the room is always packed.

I pretty much jump out of bed in the morning to go.

And the workout is incredible. I can see my body changing. And I leave each morning's class with a renewed energy and mental tune-up to hit the day with the best vibes. Thanks OTF Millburn!

While visiting NJ for business, I went to a few classes at OTF Millburn. The staff is friendly and the coaches are good. Coaches have good energy. Not rated 5 stars as some pieces of equipment need up keep/ replacement and cleanliness is lacking. The studio needs a good dusting and cleaning and members aren't always mindful of wiping up after themselves and there is sweat leftover on the treadmills/ railings, rowers and mats. OTF has wipes everywhere to make sure we wipe up anything we touch and sweat on.

Fun, varied, effective workouts that fly by! I’ve tried many group fitness classes and OT is my favorite by far. Nothing else could drag me out of bed for 6am workouts.

My daughter recently took a class Monday 12/18/2023, She was highly disappointed because Coach Kayla yelled at her employee and almost made her cry. Highly disappointed with Millburns management. This is a place I will not recommend anyone to go to.

I've been going to Orange Theory Millburn for half a year now, and it's been an incredible journey. The coaches here are truly amazing – they're not just trainers, but motivators, cheerleaders, and experts in every way. Their enthusiasm and energy make every session fun… and the results are visible. I leave every session feeling accomplished and energized. Highly recommend this place to anyone looking to improve their fitness in a supportive and vibrant environment.

I’ve been doing Orangetheory for years and anytime I leave I always come back because it’s the most effective workout I’ve found. Orangetheory Millburn has top-notch trainers and a great facility. I travel a lot, but this is my homebase and I love it!

I've been going to this Orange theory for years now. I love it. It's the only gym I actually enjoy going to. Coach Karlea & Coach Gina are the best! They motivate you to do your personal best and keep the classes fun with great tunes. Highly recommend giving it a try.

I love Orange Theory Millburn! The coaches are all incredible, the perfect mix of friendly and motivating. I particularly like that the floor routines often incorporate medium-heavy weight lifting, not just light weight. And the music is great!! This is the only gym or studio where I’ve consistently looked forward to going.

I recently went to a class at the Millburn studio and was a little skeptical due to bad reviews about the management staff. I have to say that all of the staff especially the new studio manager Cody were awesome!!! Cody was extremely helpful and welcoming and brought a great energy to the studio.

The staff and coach could not have been nicer at this location. I saw a couple of old reviews about management but I met the manager Cody when I used this location a few days ago and he could not have been nicer. It's always easy to judge OTF's by the lobby vibe (hint: no one wants to work out in a library!) - this lobby was pumping and the staff was welcoming. I use a lot of OTF's & Millburn has a good thing going on! I'll be back next time I'm in the area!

They make it incredibly difficult to cancel your membership. Then they scam you with a few charges following cancellation of your membership which they tell you they will reverse the charge but don’t.

great work out but really poorly managed and their staff does not go over all details at the time of sign up. When I signed up, they said next month is free and that is it. I buy their band the next day when i went to the class. 30 days later i find out i am not given free month because i did not buy the band same day as trial!!! none of their staff mentioned this the day i was signing . And now i have paid all dues and account is frozen, they are charging 15 dollars per month for god knows what.
I am now trying to just completely cancel my membership, but yet again cannot reach anyone at front desk during business hours. :(

I only started Orange Theory 2.5 weeks ago, but from the second I joined, I have been treated like family. Rachelle and Robbie at the front desk always greet me with a smile and have made me feel so welcomed. The coaches are amazing and always push me to be my best and I am so happy I joined. I truly look forward to coming everyday.

OTF Milburn is my absolute favorite location! I have been to multiple gyms in multiple states and no one compares! The coaches are so friendly and approachable and the staff at the front desk says hello to everyone and knows each members name! I always leave feeling like I got my moneys worth from the insane workouts!

This is my happy place. No, really! The coaches are varied and inspirational, as well as kind about modifications for my aging knees and questionable back. I have to say I'm a fan of the weekend 3Gs, but I go during the week, too (I shoot for 4x a week). Themed classes are fun, front desk staff are welcoming and the studio is always tidy. Oh, and the price is right.

Worst customer service I've had. I booked online for my first class. It was rush hours and I was 4 mins late (In other words, 26 mins prior the class) for the 30 mins rule (You have to arrive 30 mins before the class), then I got straight NO to attend the class. I kindly asked why and the front desk guy just replied 'well because we are strict' with very cold attitude. Honestly, I was not happy with that attitude and asked for refund, that guy was initially reluctant but finally said he would talk to his manager and update me later. Now one week past, I haven't received any update...

Ironically, after i filled my info online, I received 6 calls and 2 voice messages in 4 days, but when I decided to try the class, I feel like they don't care customers at all. I will never go back.

Pros: really enjoy the classes, the music is energetic and the coaches are awesome.
Dislike: late show policy. The grace period is 5 minutes. I arrived for an 8:30 am class at 8:36, 1 minute late after the grace period and was not permitted in the class. I believe this time frame is rigid especially for a $179 membership fee. Since the gym only has workout group classes I couldn’t workout at all which for me was not worth the cost. I was also charged $12 for arriving 6 minutes late. The class was not full. The person at the front desk could have been more flexible. on another occasion the wrist band didn’t work, the same person at the front desk replied “this happens” and brushed it away. As a new member with a band less than 2 months old that’s the last thing I wanted to hear since the cost was over $100 for the band.

It’s a bummer that I decided to cancel my membership and find a better gym with more options. Perhaps one that includes the ability to work out on my own and attend classes.

Been coming here since 2020. Great coaches and workout program! Took off three stars because poor customer services and management. If you try to reach them on the phone during business hours there are days they dont pick up and dont call you back after leaving them a voicemail. Importantly, they are constantly messing up my account (ie charging me when my account was frozen, charging me twice in a month, and charging me when i wasnt a member for few months). Management did not handle it well and wouldnt get on the phone with me. Considering the membership price is so high i expect great customer service! I love OTF but cant double check their work for them. After the last incident i decided i will join equinox which is only $10 more my current membership and they are known for their excellent customer services
