Orangetheory Fitness

Unlike many other fitness clubs, Orangetheory Fitness does not provide exercise facilities for members to use whenever and however they want. Instead, it functions more like a studio, with members signing up for workout classes throughout the day. For each class, the gym designs a new High-Intensity Interval Training (HIIT) program, and participants wear heart rate monitors to ensure that their heart rate stays in the zone that produces the best results.

Orangetheory Fitness was created in 2010, although it grew out of Ellen's Ultimate Workout, a Pilates studio that has been around since the 1990s. One of the founders is Ellen Latham of Ellen's Ultimate Workout. The cost of membership is determined by how many courses you want to take per month, and once you join, you can use any of Orangetheory Fitness's more than 1,200 locations worldwide.
