High-intensity exercise significantly boosts metabolism through the afterburn effect, or excess post-exercise oxygen consumption (EPOC). This phenomenon occurs when the body continues to expend energy to restore itself to its pre-exercise state, resulting in increased calorie burn even after the workout. Additionally, high-intensity workouts improve cardiovascular efficiency and promote fat oxidation. The intense nature of this exercise encourages adaptations at the cellular level, enhancing metabolic function. Consequently, incorporating high-intensity exercise into a routine can elevate overall energy expenditure and support fat loss goals.
