Definition: HIIT (High Intensity Interval Training) is a form of cardio which is beneficial to burning fat in a short and intense workout. Typical HIIT workouts vary from 9–20 minutes.
It is proven to burn 9 TIMES more fat than regular cardio (steady state cardio), in less time!
To get the same (fat burning) benefits of 2.5 hours a week of HIIT you would have to do 10.5 hours of steady state cardio. Your present fitness level will determine how you reach the required intensity.
It may mean alternating between a moderate walking pace and a brisk pace just as long as you are able to hit the right intensity level to produce the benefits.
