“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.”
“One reason high-intensity interval training is so popular is because a HIIT workout takes very little time. A typical HIIT workout is 20 minutes in duration, depending on one’s fitness level.””Research suggests that short, intense cardio intervals burn more body fat than sustained activity, such as steady-state cardio. During traditional cardio workouts, calories are burned only while performing the workout whereas high-intensity interval training can boost metabolism for up to 24 hours after a workout.”TheFittChick HIIT workout is to jump on the treadmill or stairclimber and do a 45 second run/sprint and jump to the side and rest for 15 seconds. The ultimate goal is to work up to 20 minutes of sprinting, with a 5 minute warm-up and cool down.
