HIIT, or high-intensity interval training, is a training technique in which you give all-out, one hundred percent effort through quick, intense bursts of exercise, followed by short, sometimes active, recovery periods. This type of training gets and keeps your heart rate up and burns more fat in less time. A high-intensity workout increases the body’s need for oxygen during the effort and creates an oxygen shortage, causing your body to ask for more oxygen during recovery. This type of training causes what we call the "After Burn" Effect, burning more fat up to 18 hours after the workout is over!
