HIIT (High Intensity Interval Training)
HIIT has several positive effects and proves to be one of the most efficient ways of training in the least amount of time. It differs from regular interval training in that it is more intense. Even the rest periods can be more advanced.
HIIT is alternating periods of fast, intense exercise with less intense recovery periods. During the high intensity exercise, more calories are burned within a shorter period of time.
Besides being a fast and efficient way of burning calories and fat, HIIT can also improve cardio respiratory fitness, improve recovery time and studies show it increases insulin sensitivity.
