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!

Organized, energetic, great atmosphere, encouraging coaches, clean space. Loved the vibe from day one. One hour intense class gets your day started like nothing else.

Super fun with a knowledgeable, friendly and energetic coach!

Awesome workouts and great coaches!

Ive been a member here since they opened over two years ago and love it. The coaches, sales associates, and members are all great. The workouts are challenging and different from day to day, there are fun activities from month to month, and the coaches and members make the workouts fly by!

Love the place and the workouts, the staff and coaches are great. Brandon and his team helped me sign up for the class. They were immensely helpful, Brandon is always professional and offer assistance when needed. Highly recommended.

This is such a great workout! You feel energized after every workout. I love the schedule, it works well with my availability. I love that no matter which coach you get, the quality of the class is great, and every workout is different, challenging, and you just want to go back for more! Loving OTF @ Assembly Row!

Try an Orange Theory workout if you havent. They make an hour fly by with a variety of activities that keep you interested and working hard. The heart monitors provide real-time feedback (and confirmation) that you are pushing hard enough and getting all the benefits of your workout. After, they email a visual report on your workout so you can see how you did - and its a great progress tracking tool, too!!

I like the intensity of the workouts and the variety from class to class. It really keeps me on my toes. Since I dont have to think about what I have to do I can focus all my time on giving max effort. The coaches also do a really great job of explaining all the exercises to be performed. And I like how the class can accommodate all levels of fitness.

Ive been a member since they opened their doors and I have been 100% satisfied with their level of service, enthusiasm, & support--- the staff & coaches are honestly the best!

You never get the feeling that the coach is there because they HAVE to be. Theyre never going through the motions, which in turn encourages me to do the same, to give my all. The instruction is straightforward and clear. An all around fantastic workout every time I go.

Great classes. Great energy. Great atmosphere. All the instructors try to get the best of you, always in a safe way. I have low back problems and they always offer me an option to do the exercise. Cant get enough!

I love the workout and the way it changes every day......no chance of getting bored!! I love that the hour goes by so quick! I love all the coaches they are all so nice and supportive and just the right about of intensity to make you push harder! I love that if an exercise doesnt work for me Im given options I dont have to kill myself trying to do something that will end up hurting me. Overall I LOVE ORANGETHEORY!!!!

Very effective classes, made easy for everyone involved with everyone equally included. Very nice staff all around with great facilities. Will definitely be going back!

I played College Basketball and Orange Theory is by far the best workout that I have found since then. The trainers get to know you and keep you motivated. You look forward to coming to classes. The workouts are always different, keeping you surprised as to what you will be doing that day. Your constantly working different muscle groups. You are focoused for 1 hour never having to wait for machines or weights. The Assembly Row location is immaculate! The fitness equipment is very well maintained and clean. The staff is always friendly. I would highly recommend Orange Theory Fitness! You will love it too!

OrangeTheory member for 4+ years now. Two years at this location and previously a member at another location. The Assembly Row coaches are not as motivating and personable as coaches at other locations I was a member of. Most classes are also 3G at Assembly location despite not being full enough for a true 3G class on a regular basis. This is extremely frustrating as a member who joined years ago based on the original 2G group classes... Other locations have significantly more 2G classes than Assembly. I’ve also not been allowed in with their new “5 minute late” policy, yet I’ve been in class when people have come in 10 minutes late. I love OTF, but this location is far from the best.

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!

This is the only 1 hour workout I have ever done where I feel like I have pushed myself to the max. The workouts change so much from day to day that I never get bored. The staff and trainers are all so nice and the trainers help you with your form so that you can get better. Assembly is a great facility and I look forward to what is to come! Orange Theory rocks!

My worse Orangetheory experience ever! The coach was new, the fan was blowing hard on the weight lifting area and the wind was blowing everyone away! Such an uncomfortable way of doing weight lifting and when I raised it to the front desk and the manager attention, they all looked as if its the first time they ever noticed it! Just a very poor customer service and a terrible experience overall. Do not recommend this branch although unfortunately there are not many other options around.

I was here for the first time. The class is at 130pm and they have this policy you have to arrive 30 mins earlier and I got that. They called me twice, at 1230pm and 1255pm. I was driving couldn’t answer the phone. I called back at 1pm after I arrived at assembly and was told I was late and not allowed to join the class due to their policy. I literally drove all the way here, hit some traffic, was right at partners garage made this call 30mins earlier and got denied told me to head back home. I think couple minutes really bothers them and wasting my life driving back and forth doesn’t really matter.

Good workout, nice facility, but of the 3 OTF studios I’ve tried in my area, this was my least favorite! The staff isn’t welcoming. They don’t make eye contact or greet you when you come in. They don’t take questions well, I felt as if I was putting them out by asking simple questions... I.e. where can I fill my water bottle, can you confirm my monitor is online, etc. The coach was especially cold. She went through set instructions WAY to quickly, seemed very bothered when I asked for follow-up (all but rolled her eyes at me), and just wasn’t motivating or friendly.I’ve had some really nice experiences as a new OTF member, but Somerville was NOT one of them.

Awesome work out. Beautiful facility right in Assembly Row (by the orange line). Jasons a great trainer -- thanks for pushing me to the max!

I just started taking classes at the brand new Orange Theory Fitness at Assembly Row and so far I really love it. The classes are always different and the hour goes by so fast. I am easily intimidated by gym weight rooms and group fitness settings and OTF solves those problems for me since weight training is incorporated into every workout and I am so busy focusing on myself, I forget about everyone else in the room. I am really glad I joined and am looking forward to taking more and more classes!

I love the energy, the coaches, that the workout is always changing, and that classes go by quickly. The coaches truly encourage and understand the balance between pushing yourself and going at your own pace, which makes the room feel positive.

I definitely recommend this to anyone who is serious about fitness goals. The thorough design of workouts shows the amount of research and study they have done. I am really satisfied to join this class.

I have been going to OTF Somerville since they opened summer of 2017. The staff has been incredibly friendly and helpful, the coaches have motivated me in ways other gyms have not, which has helped me keep a healthier lifestyle and in turn helped me lose and keep off 20 lbs since starting. . They offer a variety of class times throughout the day that fit my schedule and best of all it challenges my entire body by giving me the best of both worlds (cardio and strength training).

The orange theory experience is well rounded and the trainers push me to work harder and better than I ever would on my own. The scheduled classes hold me accountable so I actually go and its an hour of sweat, fun, and feeling good.

What an awesome workout! Ive been looking for something for a long time that challenges me physically and mentally and this class does it for me every single time. The trainers are also awesome (especially Reegan!!).

I want to start by saying I think fitness classes are generally kind of stupid and unnecessary. With a basic gym you should have everything you need to increase your fitness. ...but Ive had such a hard time dragging myself to the big box gym right next to my house.OrangeTheory looks like a bunch of overpriced hype from the outside. My fiance started doing it and convinced me that it was fun and the workout was brutal. I used to go to a crossfit gym which I liked, but its crazy expensive and hard to get good at unless you go most days which isnt practical for me currently. I love the heart rate monitor and the screen, though I think it doesnt work perfectly all the time. The treadmills are the 2nd best Ive ever run on (bulging discs in my back) second only to the TruForm runner you would find at a crossfit gym. The instructors have all been really positive without being annoying and intrusive. The people who work at the desk are very pleasant and try to be as helpful as possible. Occasionally there are issues with the tech, mostly the app, but the website always works. I LOVE that rowers and treadmills always take up a bulk of the time because those exercises are unmatched.I only write reviews unless something is absolutely horrid or fantastic. OTF in somerville has been the latter. Im legitimately excited to exercise again.However - dont really buy the calorie number thats given to you at the end. Its based on a measure thats pretty well studied but measuring metabolism is debated in the literature. Regardless - its a super consistent way to make sure youre working hard and pushing yourself. I love that. Cant ask for anything better.The negative reviews on here are kinda funny. Their policy is STRICT and OBVIOUS about being on time. I like that. No classes are impacted by people being late or staff having to go attend to other things during the workout. The facility is nice. Its clean. The equipment is in great shape.

Love Orange Theory! It was well worth the wait for them to open! Ive only had multiple classes with Reegan, Jason and Hua and they are all awesome and make waking up at 4am for a 5am class worth it!

I like the way how the trainer pushes to strive more but still allows you to workout at your own pace and level. You definitely get encouraged and not intimidated.

I am 66 years old. I have titanium knees. Jason kept an eye on me and everyone. Of course I was sore the next day, no pain no gain. I have got to admit, not as much pain as I expected.

The coaches are motivating and helpful during the workouts. The other staff members are also super friendly!

The workouts are similar to others ive done at otf. the coach (jason) was very energetic though, checked-in a couple times with some corrections to my movements. that doesnt always happen at my home studio

Love the Somerville location. More space for using weights

Instructor was great, she kept us on track with all of our exercises and motivated us during the all out segments !

Friendly staff. Good locationt

Great place to start your fitness goals...but little expensive

Amazing workout, great coaches, and super friendly front desk staff. Its a bit pricey but worth it.

Location itself is a motivator, Ive had to classes with Jason, and the tempo that he sets is great!

Im willing to give it another shot.

If you dont have the condition for Tabata-styled HIIT routines, but want a high-energy routine that youll push yourself through, this is the place!

Fantastic and friendly staff, clean facilities, the best workout!

Clean and new - beautiful gear!

Great workout ever!

I burned almost 600 calories!

Love this location

I love orange theory!!
