Interval training enhances metabolic rate post-exercise through the concept known as excess post-exercise oxygen consumption (EPOC). This training method alternates between high-intensity bursts and lower-intensity recovery periods, which raises heart rate and energy expenditure during and after workouts. Following high-intensity intervals, the body continues to burn calories at an elevated rate as it recovers, replenishes oxygen stores, and repairs muscles. This post-exercise calorie burn can lead to improved overall fitness and efficiency in weight management or fat loss. Incorporating interval training can be a highly effective strategy to boost metabolic activity.
