For those of you who are unaware, the acronym “HIIT” stands for High Intensity Interval Training. Simply put, this is a method where you alternate back and forth between a high and low intensity while you work out.
Over the course of time, this training style has gained popularity with all age groups and demographics for its effects on the body and for the fact that it burns more fat than any other workout.
Not only does it cause a high caloric expenditure, but it also cranks up your resting metabolic rate, and boosts your body’s natural production of human growth hormone and testosterone. This translates to a leaner, more defined body with a low amount of body fat.
