What does the "orange effect" refer to?

The "orange effect" refers to the heightened metabolic boost and calorie burn that occurs after intense workouts. This phenomenon is associated with the afterburn effect, scientifically known as excess post-exercise oxygen consumption (EPOC). After completing high-intensity exercise, the body continues to burn calories at an elevated rate as it recovers and restores itself to resting levels. The concept is central to the philosophy of Orangetheory Fitness, which emphasizes the importance of maintaining a high heart rate during workouts to maximize calorie burn not just during the session, but also afterward.

The other options touch on important aspects of exercise and its effects on the body, but they do not capture the essence of the "orange effect." Reducing blood pressure and increased recovery time are benefits of regular exercise, while temporary energy loss can be a challenge during high-intensity workouts, but none of these accurately define the unique metabolic boost resulting from the intensity and structure of Orangetheory sessions.
