48: The number of hours your body can keep burning calories after a HIIT workout. 

5: The number of calories burned per liter of oxygen consumed during a HIIT workout, according to the American Council on Exercise.

58 is the number of calories burned in five minutes of running at 7.5 mph (eight- minute mile). 

27 minutes is the length of a HIIT workout necessary, three times per week, to equal 60 minutes of steady cardio five times a week. 

Why does HIIT burn fat so well? Doing short intervals of high-intensity exercise, especially those that involve a lot of muscle mass, requires
a tremendous amount of oxygen (and therefore calories burned) during both the work interval and the recovery periods. 

HIIT Training has been shown to provide a variety of health benefits, including improving blood pressure, cardiovascular health, insulin sensitivity, cholesterol profiles, abdominal fat, and body weight while maintaning muscle mass, according to the American College of Sports Medicine.
