Orangetheory is amazing in general but Mercer Island is by far the best gym. They are organized, clean, friendly and super welcoming to all activity levels. I started there in June thinking I would never exercise again after having a baby and now, in September, I’m training for the Seattle half marathon and feel better in my body than I ever have. It’s such a fun work out that you don’t even notice how hard it is. And so much cheaper than a personal trainer.

Amazing experience! With traditional gyms I always feel isolated and out of place, plus it’s often times hard to stick with a consistent routine if the gym is crowded. With Orange Theory, you always feel included, you always have a reserved piece of exercise equipment, and you always had a real time readout of your health statistics and the quality of the workout.

From day one the team offered me modifiers to keep me feeling challenged but safe! They are the most encouraging, energetic and fun group, I could not imagine going anywhere else.

Great coaches, very encouraging, very helpful in correcting form. Marina at the front desk is top notch as well. Proud to call this studio my home base!

My wife and have been going to the MI OTF since they first opened, and we became founding members. I must say I was a little hesitant to join at first as I like working out on my own in a less structured environment. That said however, I’m glad I took the plunge as it has likely become one of the best decisions I have made regarding my health.Although the workouts are very structured, they can be tailored to meet any fitness level. Looking back, it is amazing to think about how fay my wife and I have progressed.All the trainers are great, and we particularly enjoy working with Vinney & Haley, and Amy does a great job managing the shop!Highly recommended; if you are looking to get out of a rut and get your health and fitness on track, this is the place for you!

I loved the trainer, Vinny-very personable and easy to understand. This was my first group fitness experience so I was a little nervous but it was great. Everyone is so busy doing their workout and so much is going on you dont have time to worry about it. It was also an amazing workout, definitely challenging but in a good way.

Great place. Great coaches. Its nice to mix up my routine when Im not running and get some inspired core and strength work in.

Absolutely amazing staff. They really do care about every indicidual that walks in their door. Their workouts are also absolutely amazing! They helped me lean out, as well as get toned (which I honestly didn’t think was possible for me)! They helped me regain my confidence and taught me how to push myself to achieve a full workout. I 100% recommend going here for an amazing workout and an extremely positive environment. Very thankful for all they do.

Ive been to a lot of OTs around the country and cannot find one better than Mercer Island. Great coaches (Hailey, Melanie, Vinny - and our new coach, Dominic) are amazing and the front desk crew is friendly and really helpful! Its a great work out which feels like personal training in a group setting. Ive lost 40 pounds and have improved my overall health!

Tried a free class. It was very good. Will take classes for two months and see how it goes.

I love Orange Theory! This place is my favorite exercise cult ever! Seriously though. You must try it!

Best hour workout I’ve ever had! The coaches are very motivating and the music is awesome. I’ve tried plenty of other fitness programs but this is the only one I’m excited to go to!

The workout is good, intense and you feel accomplished when youre done. And fundamentally, if thats all they promised then it would be fine. But the place is called Orangetheory because they have a strong philosophy about how your intensity should change through the workout and provide you with extensive stats following. And this is where they have failed me. Ive been to 3 classes and each time their heart monitor has failed. Once I wasnt on the board at all, once it looked like my heart rate didnt move for 75% of the class and once it didnt register until about half way through the class. They told me that it was registered incorrectly and next time it would be better. Then they told me that my age was entered incorrectly. Whatever is the excuse, I feel like Im not getting the benefit of the theory and not able to chart my progress without their heart monitor performing. I will quit my membership if this happens again. Its poor service for a heavily marketed benefit

I love this bright and fast-paced studio. When I had an issue with my heart rate monitor the manager was incredibly helpful and I ended up very happy with our interaction. The instructors are great, And I especially like Vinny. I would recommend MI OTF to anyone looking for a great workout.

Excellent workout! High energy, not too much time on any one activity, and I don’t have to think! I loved my old gym. But, I moved and Orange Theory definitely makes up for it!

Everything is great, customer service has really stepped up! Love the happy thoughts early in the morning! Always ready to take on the day after a good workout with these motivating coaches!

The class is unique, fun, high energy and always has great music. They begin and end each class with a warm up and cool down which I think is so important.

Love the community, each day is different, great music, excellent supportive coaching, and very fun and challenging.I love the program! OTF has made me stronger, happier, and healthier. The community has supported me in my renewed committment to my health.

My niece was visiting from out of town and my wife and I tagged along to experience Orange Theory for the first time. Now we understand how she got so fit in just a few months. We went back after she left and will be going 3xweek now. Wonderful staff and beautiful exercise setup. Great trainer both times and new & shiny equipment that works perfectly. Would give 10 stars if the scale went that high,

The Coaches are amazing, they are able to provide work around if I have a physical limitation to deal with. The studio is beautiful and clean. All employees at OTF are so caring and friendly. My workouts feel like they fly by, most days.

Great coaches and staff, would recommend.

Great workout, excellent training by expert trainers. I enjoyed the time spent in Seattle

Orange Theory has helped me reach so many different fitness goals over the last year and a half! The coaches here genuinely care about their members as well!

Great place to have an efficient and fulfilling workout. Coach Vinny is the best!

I love Mercer Island Orange Theory Fitness! They’ve got motivating coaches, tough work outs, and a variety of times every day to fit into your schedule.

Had my first workout this morning and it was so good! Staff were all awesome (shoutout to Jared, coach Vinny, and studio manager Amy who provided some extra support in class to us newbies). Apparently this week is a bit unusual class-structure-wise; regardless, the workout was intense and yet modifiable to every level/need, either to push harder or to listen to your body.The studio was nice - not huge, everything was organized to be functional, it was clean, and I enjoyed the class playlist a lot.My favorite quote from the coach was about the importance of “getting comfortable with the discomfort” that comes from pushing yourself. That mentality totally aligns with the fitness success in my past. I’m super excited about going back the next time.

Great energy from Kevin - keeps you motivated through the entire class! Upbeat music and tough workouts to make it well worth your hour!

I love that Im getting a full body workout every time! The coaches are so encouraging, motivating, and above all, supportive! Love my OTF family!

Very clean studio. All the staff are friendly and knowledgeable. I feel energized and yet relaxed after taking a class.

Workout that kicks your ass but in a good way, no time to think or try, one must just do it! Clean up to date and inviting environment, staff is friendly & encouraging

OTF is the best gym I have joined. The coached 1 hour group sessions with different exercises everyday is cool. The mix of strength and cardio is awesome.

Love the upbeat and high energy! A great workout every time I go!

Love OTF. MI wasnt crowded at the 8am class. I Had Coach Vinnie whos great. MI isnt my home club so this was my first visit. Its a Nice club and nice location. MI is a really excellent studio with great natural lighting through the large windows.

The staff and leadership seem wise and kind.Highly recommend!!

This place is a well oiled machine.It runs smooth and the vibe is always very positive!!!

Coach Vinny was awesome and the studio was so nice!

Amazing workout, clean studio and great staff. Love it!

Great staff, super rewarding workout. Tough but SO much fun!

Great staff, excellent full body workout, amazing coaches, & beautiful clean studio.

I love orange theory workouts and this location and staff are the best!

The workout is amazing and the instructors are fabulous! The atmosphere and community is so wonderful and encouraging for all fitness levels. However, I ended up having to cancel my membership when the 8:30pm classes were taken off the schedule. I called to cancel and was told I had to come in person to complete paperwork (and with my schedule this was difficult to do; I had to take unpaid time from work to do so) and then I discovered my membership was not cancelled! My credit card is continuing to be charged even after completing the appropriate paperwork. I also had issues with the OTBeat app and trying to set up my profile. When I inquired at the desk, I was told that only the manager knew how to set up the information to sync the monitor to the app. The employee told me she would leave a message for the manager to call me back. I also emailed to follow up yet never heard from the manager. So I know have been charged an extra $150 even though Ive cancelled the class as well as paid $60 for a heart monitor device I cannot use outside of the OTF studio as I was not able to set up the OTBeat app.Overall, the class and instructors are wonderful but dealing with OTF has been extremely frustrating.

Im a certified personal trainer but sometimes I still need to be yelled at to push myself. I can always count on OrangeTheory coaches to do that for me. :)

Easy to schedule classes, good workouts, knowledgeable instructors, friendly staff!

I have a desk job where I sit for 10 hours a day, and have been sedentary for at least a decade (with fits and starts of workouts never lasting more than 1 or 2 times). I started OTF at the end of March right before my 40th birthday upon the encouragement of my totally fit friends. Needless to say, I was completely intimidated to try. I figured I would go once to get them off of my back. I ended up signing up for a membership after the first class. I was blown away by the intensity of the workouts, but most of all, am amazed by the GENUINE support of the coaches and other athletes. I am now a total convert and have made some great new friends and know Im on a permanent path to a healthy lifestyle. Thank you Mercer Island OTF!! #NewDecadeNewMe

Always enjoy the workouts - great staff and great program

The staff and coach’s are amazing !

Great place, good sanitation.
