Interval training is effective for fat loss because it alternates high-intensity activity with periods of rest or low-intensity exercise, maximizing calorie burn and boosting metabolic rate. This training approach elevates the heart rate considerably, promoting greater post-exercise oxygen consumption (EPOC), which leads to continued calorie burning even after the workout. Additionally, interval training can be time-efficient, providing significant results in shorter durations compared to steady-state cardio. The variety in intensities keeps workouts engaging, making it easier for individuals to adhere to regular exercise, thus supporting long-term fat loss goals.
