What is HIIT?
High-intensity interval training (HIIT), also called high-intensity intermittent exercise (HIIE) or sprint interval training (SIT), is an enhanced form of interval training, an exercise strategy alternating periods of short intense anaerobic exercise with less-intense recovery periods. HIIT is a form of cardiovascular exercise. Usual HIIT sessions may vary from 4–30 minutes. These short, intense workouts provide improved athletic capacity and condition, improved glucose metabolism, and improved fat burning.
This definition comes from wikipedia (http://en.wikipedia.org/wiki/High-intensity_interval_training) where you can find a lot more information about its benefits. It also explains some very popular programs, like the tabata. HIIT is also a common practice in Crossfit trainings.
