High-intensity training (HIT) significantly impacts calorie burn, both during and after workouts. Such training boosts metabolism through the principle of excess post-exercise oxygen consumption (EPOC), leading to an increased calorie burn even after workouts. By combining short bursts of intense effort with rest periods, HIT encourages the body to utilize stored fat more efficiently. This efficiency promotes greater fat loss and improves overall fitness levels. As a result, incorporating HIT into exercise routines can lead to sustainable weight management and enhanced physical performance.
