“HIIT” training, or High intensity interval training, is a recently popular technique to burn calories and get in top shape. The work-outs use several very intense intervals of cardio followed by short rest periods for the body to recover. The work-outs are typically between 5-30 minutes, which makes them convenient for even the busiest person.
Typically a HIIT session starts with a basic warm-up which could be anything from walking to cycling. The workout consists of approximately 3-10 episodes of high intensity exercise interspersed with moderate intensity. The activity varies from person to person, moderate activity could be walking or a light jog, and high intensity exercise could be jogging, walking an incline, stair climbing, or aerobics of some sort. The primary goal is to raise the heart rate safely, and then allow it to lower during moderate intensity exercise.
Benefits include timeliness, aerobic exercise, increase in athletic performance, reduction in cardiovascular disease risks, and a reduction in fat. There is also evidence suggesting HIIT decreases insulin resistance and improved glucose tolerance, important factors in reducing risk of diabetes.
