What is the goal of the "Orange Effect"?

The goal of the "Orange Effect" is to extend calorie burn after the workout. This concept is central to Orangetheory Fitness and is based on the idea of excess post-exercise oxygen consumption (EPOC), commonly referred to as the "afterburn." During a workout, particularly when engaging in high-intensity interval training, the body uses up energy and, once the workout is over, continues to burn calories as it returns to its resting state. This extended calorie burn occurs due to the increased metabolic rate resulting from the intense effort put forth during the training sessions. By design, Orangetheory workouts are structured to elevate participants' heart rates and push them into different intensity zones, maximizing the afterburn effect and making workouts more efficient for calorie loss.
