High-intensity interval training

High-intensity interval training (HIIT), also called high-intensity intermittent exercise (HIIE) or sprint interval training (SIT), is a form of interval training, a cardiovascular exercise strategy alternating short periods of intense anaerobic exercise with less intense recovery periods. HIIT is the concept where one performs a short burst of high-intensity (or max-intensity) exercise followed by a brief low-intensity activity, repeatedly, until too exhausted to continue. Though there is no universal HIIT session duration, these intense workouts typically last under 30 minutes, with times varying based on a participant's current fitness level.

HIIT kickstarts your metabolism and helps you burn fat faster. If one wants to lose weight, one should incorporate HIIT into each work out. The point is to push yourself, take short breaks, and then max your body out. Working past that fatigue makes the body stronger and builds endurance.
