Interval training maximizes calorie burn during workouts by alternating between periods of high-intensity and low-intensity exercise. This method boosts metabolic rate due to the high level of exertion, leading to greater calorie expenditure during and after the workout, a phenomenon known as the afterburn effect. By incorporating various intensities, interval training can enhance cardiovascular fitness and improve endurance faster compared to steady-state training. The structure of this training keeps workouts engaging and adaptable, catering to different fitness levels. Therefore, interval training is an efficient and effective approach to achieving weight loss and fitness goals.
