HIIT workouts generally combine short bursts of intense exercise with periods of rest or lower-intensity exercise. At fitness studios and online, these workouts often mix aerobic, dance and bodyweight exercises. As you can tell from the name, high-intensity interval training (HIIT) is challenging. It takes your cardio workout to another level, as you push your pace out of your comfort zone.
You’ll work up a sweat fast, working at a very intense level and then backing off for a slower recovery period, followed by another round of high intensity. You’ll lose weight, build muscle, and boost your metabolism. Plus there’s a post-workout bonus: Your body will burn calories for about 2 hours after you exercise.
