A great workout experience. Everyone working there is very friendly and the class itself will always make you work hard regardless of your fitness level. It's a good time!

Every time I go to a class at OTF Assembly, I feel like I’m going to a workout class with up to 41 other friends. The staff is extremely welcoming, always has answers to any question I have, and is incredibly motivating. They know when to push me, but they also know when to go easy on me. It’s by far the best OTF in the greater Boston area!

Friendly staff, I wish they would check vaccines and better enforce the mask mandate but I get not wanting to cause a confrontation. Luckily I can go when class isn't full and I wear a kn95 and the staff works with me to find emptier class times!

Pros: They get two stars for nice staff. Cons: - 30-day money-back guarantee is bogus. Don't sign up lightly because they'll make you fight to get your money back. Also, there is no cancellation option on the website or the app - you need to ask for a cancellation form and then you'll still get charged for any payments scheduled in the next 30 days! Feels like this company is trying to sneak a few accidental payments out of you, but that is a different rant. - This location is BUSY - get ready to work out at times other than the ones that are convenient or planned - They fail to mention that you need to buy their branded heart-rate monitor to participate in the classes, and no your own device will not substitute. - My girlfriend got simultaneous strep throat AND covid-19 from one of the classes! When she was out of commission for almost a full month they wouldn't give her a refund So if you want an intense workout class, sure, this place is fine. But get ready for an over-priced experience where you just feel like a faceless customer

Came in with my sister today, space was very clean& welcoming. Nicole lead a great workout! 👍

I’m town visiting my daughter and I Arrived thinking I was going to a different studio but so glad I stayed and waited for the next class! The staff were so friendly and nice, plus free parking and this location didn’t have an up charge 😀 Overall great experience! LOVED THE CLASS

The studio is in great shape. Coaches are very helpful, professional and lotsa positive energy. The studio vibe is friendly and welcoming.

Had a wonderful first-time workout with coach Emily at this location! She was SO thoughtful during the introductory session, and her playlist totallt rocked. Claire at check-in was also SUPER nice. All around a GREAT experience. Thumbs up Orangetheory!

Orange Theory's standout is its stellar shower facilities, a welcome retreat after their brutal workouts. The competitive edge with "splat points" adds excitement, but the structured workouts may eventually grow monotonous. In a nutshell, excellent showers, challenging workouts, but potential for workout fatigue over time.

I’ve been doing OTF for about 3 months now and I can’t say enough good things about it. My home studio is in Waltham since my office is out there but I love coming to the Assembly one more. Coach Ryan and Coach Emily are easily the best coaches I’ve ever had. They make each workout fun and really want you to do your best. If you haven’t tried your first class, get on it! You don’t be disappointed.

OTF is great! Hits all different muscle groups and the rotational aspect makes every time a full body workout.

Amazing place to improve fitness levels. Fun classes, great coaches and very welcoming staff. Studio is spacious and does not feel congested They keep the studios, equipments and the place updated and clean. Parking is easy as there is a garage behind which has 3 hour free parking.

Terrible place, will never come back again. Staff called me during working hour. After the call, I Signed up for the first free class at 7:45pm, never been to this area before, I was told by its staff parking is easy but it took me 20min to park. There was no sign outside the building, took me another 10min to find the actually studio. I was late for 5min and the door was already closed, there is no front desk, I had to wait outside for 10min until someone showed up and told me I can not join today. I ended up talking to another studio on the same floor, the front desk is much more helpful and welcoming, I signed up their membership. ========= response ========= During my initial phone call, it was not communicated to me that a health examination and a waiver would be required prior to my first workout. I was only asked if I could arrive 20 minutes early to speak with the coach, which left me unprepared for the expectations set upon arrival. Furthermore, after waiting outside for 10 minutes, I found the staff's response rather indifferent, lacking warmth and welcoming. Unfortunately, no further explanation or follow-up was provided regarding this issue. These circumstances culminated in a less than satisfactory experience.

OTF Assembly is a great fitness studio. The coaches and members are very friendly and helpful. Great workouts. Every day the workout changes so you do not get bored and you can set your own goals on what you want to achieve whether it is rowing, treadmill or lifting weights.

I love being inspired by other peoples energy and OTF definitely exudes huge energy form its employees and other gym enthusiasts.

Everything is amazin!! We workout and don't see the time goes... The staff, the place, equipment, the vibe, everything is absolutely enjoyable!! I'm in love and workout never were so good!!

An amazing environment to workout in. Went for my free class and I was hooked from day one. The coaches at Assembly Row are motivating and helpful in every way. Their front desk staff has been nothing short of amazing. I have been going for about a month now about 5-6 days a week and have already seen an increase to my fitness capacity. I look forward to what the next few months bring. I highly recommend at a minimum trying one class and see how quickly it makes a workout fly by.

1. The level of energy from coach and the overall vibe. 2. Music 3. Ease of booking classes. 4. Facility/available parking options nearby. 5. The workouts are challenging but not too difficult and discouraging. 6. The variety of challenges (i.e. 1 mile benchmark run), which makes the workout fun. 7. Love all the coaches!

There's a reason why this gym has 5 stars. Every time you step in this gym it's just like walking in the door to your family.

I am so glad that I signed up for Orange theory fitness and specially the assembly row location. There are lots of good trainers here, that they will get sure that you are doing the workout in a correct way. Also, the front desk people are very friendly too.

In addition to this being the most challenging workout I have ever done, I absolutely love every class. The workouts are lead by great instructors, the music is awesome and the design of each workout is intense but able to be done at your own pace. The ability to continue to challenge yourself is super motivating. I am so glad OTF Assembly Row has opened, and will be making very good use of my unlimited monthly membership!

love everything! location, price, free parking, class size, the coaches, THE MUSIC PLAYLIST!! the studio and the constantly changing workouts!

Wonderful!! I’ve been to multiple OT locations around the country and hands down this one is the best. From the coaches to the front desk, everyone is super helpful, motivating, and fun. They’re willing to work with you and take the stress out of the process. Definitely join!

OTF in Assembly is the best choice I’ve made in 2022 to ensure I reach my fitness goals!! The coaches are incredible and have a lot of fun with everyone in class. Excited to continue training with the team at OTF!

OTF Assembly is one of the best orange theory studios in MA that I’ve been to! The staff is all very friendly, motivating, and organized, making each class a great experience. This is the first time I’ve found a workout I can really stick with. Since joining last November, not only have I felt physically healthier, but also my mental mindset towards exercise has shifted too. Could not recommend OTF Assembly more!!
