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. One of major benefits is that you'll see results much faster (one study found HIIT to burn three times more fat than steady state aerobic exercise). You'll also spend less time sweating in the gym. Research shows that an interval training session of 10 one-minute sprints followed by one minute of rest performed three times a week is enough produce rapid results.
You can start incorporating HIIT into your workouts today! Simply add in a one minute period of high intensity, follow it up with one minute at an easier pace, and repeat that pattern 10 times in total. It works for any type of cardio workout—on a treadmill, during an outdoor jog, on a bike, etc.
