Time Out says
This heart-rate based fitness trend takes high-intensity interval training to another level
People bang on about high-intensity interval training a lot. It is one of the most efficient forms of cardio exercise, and Melbourne gym Orangetheory is entirely dedicated to it.
Orangetheory only does group workout classes, and every session is separated into cardio and weights portions. The gym floor – which is on brand and excessively orange coloured – is set up in two sections. One half has rows of treadmills and water rowers (a bike and an elliptical is available if you have exercise limitations) and the other half has floor equipment including dumbbells, benches, TRX suspension trainers and BOSU trainers (those semicircular balls that are impossible to balance on).
Members are given heart rate monitors with their real-time results displayed on large screens in the studio. The goal is to keep your heart rate in the "orange zone" (basically when you’re feeling uncomfortable, but not in pain) for at least 15 minutes during the one-hour workout, as this is the zone where you’ve crossed the anaerobic threshold, when the body begins to burn fat instead of just carbohydrates. It feels a little like you’re playing Mario Kart, and watching your heart rate is a little addicting, especially when you find yourself competing against your gym buddies.
The workout is good for all fitness levels, as you’re able to go at your own pace and adjust settings based on your ability. Lockers, change rooms and showers are available for members, though they are small so expect to wait for a post-workout shower. At the end of each class, you’ll be emailed a rundown of how you went in class, including your average heart rate, the calories you burned and how many “Splat Points” you scored (these equate to how long you stay in the orange zone). If you’re the kind of person who enjoys knowing exactly how hard you pushed yourself, it certainly keeps you motivated.
There are three membership options, which are all at a month-to-month commitment with no contract. Their September opening specials include the orange basic ($108 per month) which gets you four sessions per month with additional sessions at a discounted rate. The orange elite ($150 per month) gets you eight sessions per month, again with additional sessions available at a discounted rate. There is also the orange premier ($171 per month) which gets you unlimited sessions per month. There are 38 classes per week available.
Best for: those who enjoy group exercise and don’t mind a bit of friendly competition
