What is HIIT?
High-intensity interval training (HIIT) describes any workout that alternates between intense bursts of activity and fixed periods of less-intense activity or even complete rest. For example, a good starter workout is running as fast as you can for 1 minute and then walking for 2 minutes. Repeat that 3-minute interval five times for a 15-minute, fat-blasting workout. It sounds too simple to be effective, but science doesn't stretch the truth. Read on for eight proven benefits of HIIT.

Super-efficient HIIT is the ideal workout for a busy schedule—whether you want to squeeze in a workout during your lunch break or to get in shape for a fast-approaching event. Research shows you can achieve more progress in a mere 15 minutes of interval training (done three times a week) than the girl jogging on the treadmill for an hour. (Watch and try this video of a 10-minute fat-blasting cardio routine that burns more calories than a half hour on the treadmill!) And according to a 2011 study presented at the American College of Sports Medicine Annual Meeting, just 2 weeks of high-intensity intervals improves your aerobic capacity as much as 6 to 8 weeks of endurance training.
Easy to keep going
“HIIT is more enjoyable than low intensity steady-state exercise,” says Tom Holland, MS, CSCS, CISSN, an exercise physiologist. Science backs this up. One study found that people reported much greater enjoyment of HIIT over continuous vigorous-intensity exercise and continuous moderate-intensity exercise. But beyond getting a kick out of your workout, you’ll also be more likely to stick to a workout you love, Holland says.
The American College of Sports and Medicine said that High Intensity Interval Training helps you consume more oxygen than a non-interval workout routine. The excess amount of oxygen consumed helps increase your rate of metabolism from about 90 minutes to 144 minutes after a session of interval training. Thus the increased metabolism helps burn more calories at a faster rate.
