High-Intensity Interval Training gives your metabolism the boost it needs in order to effectively burn calories, which is what you need if you are trying to shed a few pounds. The American College of Sports and Medicine found that those who perform High-Intensity Interval Training consume more oxygen in comparison to those who don’t, and this extra oxygen actually helps to significantly increase your metabolic rate. This increase of oxygen is what also helps to keep your blood circulating at its best and puts less stress on your heart as it pumps. Not to mention, around 15 minutes of HIIT running is roughly equivalent to an hour on the treadmill. After performing high-intensity workouts, your body takes some time to go into repair mode. During this time, your body actually continues to burn calories for up to the next 24 hours; something you don’t get from your normal workout routine.
