High-intensity exercise has a profound effect on metabolism, often leading to an elevated rate of calorie burning even after the workout is completed. This phenomenon, known as excess post-exercise oxygen consumption (EPOC), results from the body needing to restore itself to its pre-exercise state. During high-intensity workouts, the body uses both aerobic and anaerobic pathways, which can significantly increase energy expenditure. As a result, individuals engaging in high-intensity training may experience faster weight loss and improved metabolic rate, contributing to better overall fitness levels and body composition.
