Orangetheory Fitness in Waltham

I don’t live in the area and travel a lot for work, so have been to studios all over the U.S. This is by far my favorite studio to visit. Jules is an incredible owner and the studio has a great community feel. She remembers my name and where I live even if I don’t come visit for a year or more. Everyone is so nice and they always have community events going on. As a coach, Jules is encouraging and is very accurate in her timing and motivates everyone. I wish I could move to the area permanently just so I could join this community full time!

If I could give this gym more than five stars, I would. This location is really special. Coaches here don’t just lead workouts—they teach, correct, and motivate. The layout is seamless, the machines are organized, and somehow, even at peak hours, it never feels chaotic. But the real magic? The community. This isn’t just a gym; it’s a place where people show up for each other. The energy is infectious, and you feel it the second you walk in. And then there’s Coach Jules. If you know, you know. She runs a tight, efficient session and never misses a chance to fine-tune your form. She sees you, corrects you, and demos moves until you nail them. Bottom line: If you want a gym that actually engages you—where you’ll be challenged, supported, and inspired—this is the place.

I really cannot say enough good things about my experience at OTF Waltham. From day 1 we were welcomed and treated as valued members of the family/community they have fostered. The workouts push me to grow and be better, and the amazing coaches infuse every workout with enthusiasm, encouragement, and an air of celebration. And the admin staff have raised the bar for customer service. From the moment you walk in the door, through walking out you are in for a top-notch experience!

Orange theory Waltham has been my community now for 6.5 years. It is the first group workout environment that has kept me motivated for so long. I look forward to showing up to class, seeing the amazing coaches, and chatting with the studio assistants. The best part is that in addition to getting stronger I have made some lasting friendships with other members! Highly recommend checking out OTF Waltham.

The coaches and staff at OTF Waltham are the best! They are amazing about keeping us motivated in the safest way possible! I highly recommend to anyone of all fitness levels - you will have a blast and get the best sweat of your life! Thank you to the whole crew for taking us such good care of us members!

Wish I could give more than 5 stars! I love coming here! All the coaches and staff are so encouraging and friendly. I’ve definitely seen an improvement in my strength and endurance. The combination of HIIT and strength training has been extremely effective at helping me reach my fitness goals.

I LOVE OTF Waltham! I’ve been a loyal member for 2.5 years now, and I’ve never stuck with a workout/gym this long in the past. When I first joined, I was worried that it would feel too “clique-y”, but instead I’ve found a great community! The coaches and staff are so helpful and friendly, and I love that I’ve been able to make new friends with fellow members too. Plus, I get a great, well-rounded workout in, before jumping on the highway to head home after work. It’s a win-win-win!

I've attended more than 400 classes, and I have loved every one of them! The classes are always challenging but that's what makes it rewarding. Early on, Coach Jules helped me conquer some of my fears by setting new goals each class--since then I have far exceeded my personal expectations. The community at OTF Waltham is warm and supportive and the staff is always attentive and encouraging.
