High-intensity workouts can significantly boost calorie burn both during and after the session. This mode of exercise elevates the heart rate and induces a state of excess post-exercise oxygen consumption (EPOC), leading to increased metabolic rate even after the workout ends. These workouts, such as HIIT, maximize fat loss and improve cardiovascular fitness in shorter durations compared to moderate-intensity workouts. However, ensuring proper recovery is essential to avoid overtraining and injuries.
