Orangetheory Fitness

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.

I can’t say enough good things about my experience at OTF Millburn! From the moment I walked in, the staff was welcoming, knowledgeable, and genuinely enthusiastic about helping me meet my fitness goals. The coaches are incredible—motivating without being overbearing, and they always take the time to make sure your form is correct and you’re getting the most out of your workout. The workouts are challenging but scalable, so whether you’re a beginner or a seasoned athlete, you’ll find a pace that works for you. I also love the sense of community here; everyone is so supportive, and it feels like a team effort every time I walk through the door. The facility is clean, the equipment is top-notch, and the class schedule is super flexible, making it easy to fit workouts into my busy life. The heart rate tracking technology is a game-changer—it keeps me accountable and pushes me to give my best. If you’re looking for a workout that’s fun, effective, and keeps you coming back for more, I highly recommend Orangetheory. It’s worth every penny!

Love this studio! All the staff are friendly and welcoming and the coaches are super motivating and take the time to help you with form. The workouts are a good mix of strength and cardio and can be modified for all fitness levels. The team here helped me feel great (and even get stronger!) during pregnancy and get back at it postpartum.

I’ve been coming to the Millburn OT for over two years now and absolutely love it. Coach Gina is always so full of energy and an amazing coach. The workouts are fun yet challenging. Can’t recommend more!

I absolutely love Orangetheory Millburn! The workouts are challenging and fun, the energy is always high and the music is always on point. A huge shoutout to the best coaches, Gina and Karlea! They are motivating, knowledgeable, and always bring positive vibes to every class. Highly recommend this studio for anyone looking to push themselves and have a great time doing it!
