Orangetheory is a science-backed, technology-tracked, coach-inspired group workout designed to produce results from the inside out. More than a gym. Before creating the Orangetheory workout, Ellen Latham ran her own Pilates studio, but noticed her clients were still working with personal trainers. They wanted to burn fat, which Pilates alone couldn’t do. Ellen developed a workout that would “metabolically charge the body,” and the Orangetheory workout was born.
