Personalised fitness designed for all fitness levels.

Unlike high-intensity training (HIIT), Orangetheory uses variable-intensity intervals that work for a much broader range of fitness levels. With expert guidance from your triple-certified coach and real-time data from OTconnectTM, it feels like a very personalised experience: You'll quickly figure out what’s working for you — when to push and when to ease off to recover.

More personalized. Less pressure.

You don’t need to be fit to get started. Just show up—we’ve got you. With expert coaching and OTconnect™ technology, every workout adjusts to your fitness level and your goals. Whether you’re easing in or pushing hard, we meet you with encouragement and support—not pressure. Every step forward builds a body—and mindset—that’s stronger than yesterday.

I like the motivation I get from coaches and encouragement they give everyone! I love the music and the atmosphere. I can also take things at my own pace whilst feeling comfortable in the OTF environment.

OTF is more than just a gym, it's a community that inspires and supports members on their fitness journey. The classes are varied, well-structured and superbly led by the best coaches in the business. I've had various gym memberships over the years, but monotony can set in and motivation wanes. That's certainly not the case with OTF, and after 2 years, I'm as keen as ever.

Each class is different, and the support and push provided by the coach means I'm burning a lot more calories than I ever have going to a traditional gym.
