Interval training enhances fat burning during workouts by alternating high-intensity efforts with lower-intensity recovery periods. This approach boosts metabolism and encourages the body to burn calories more efficiently both during and after exercise through the afterburn effect, or excess post-exercise oxygen consumption (EPOC). High-intensity intervals increase heart rate and stimulate muscle fibers in ways that steady-state cardio cannot, leading to enhanced fat oxidation. Regularly incorporating this type of training can improve overall fitness levels, enhance endurance, and make workouts more time-efficient and enjoyable.
