Why Should You Do Interval Workouts?

What are Interval Workouts? 1 of 9

Interval workouts, also known as high-intensity interval training (HIIT), consist of alternating intense bursts of activity with less intense aerobic activity. You do this off and on throughout an entire workout.

For instance, you alternate between sprints and easy jogs, counting 1 minute for sprints and 2 minutes for jogs, or you can just sprint for as long as you can and jog when you need to.
