By now you may have heard the good news: exercising at very high intensity interspersed with periods of moderate rest, a program known as high-intensity interval training (HIIT), is one of the best ways to get in shape.

That’s good news because the workouts are considerably shorter than you’re probably used to and involve as little as four minutes of intense activity combined with rest for a total workout of only around 20 minutes.

Because HIIT is so intense, you should only do it two to three times a week, max, making it a workout that even the most time-crunched individuals can fit in their schedules.
