High Intensity Interval Training (HIIT) is a kind of training program that works your body in intense, short bursts. These intense bursts of exercise use 100 percent of your effort, but they are followed up by a short recovery program. The revolutionary HIIT design means that your heart rate stays up throughout the whole workout so that you can burn more fat in less time than you can with other programs. If you want to lose weight or keep fat off, HIIT is one of the best programs you can choose.
