What is HIIT?

HIIT is High-Intensity Interval Training. It is a type of workout that alternates between high-intensity activity and moderate or low-intensity activities. HIIT workouts are gaining popularity in the fast-paced world.

Another example is dividing twenty minutes into four sets of five minutes each. First, you run with your maximum potential for three minutes (high intense activity). Follow it by walking slowly for two minutes (low intense activity). Repeat the process for all four sets.

The intense workout and breaks are alternated and repeated for the HIIT session. An ideal ratio of workout to rest period should be 1:1. However, you can increase it gradually. Remember that the rest period should not be longer than the active period. The rest period can be complete rest or low to medium intense activity. It depends on each person’s capacity. Initially, you may need full rest periods. But as you keep pushing your limits, you may be able to do low-intensity exercise during the breaks. The active period should be a burst of short, high-intensity workouts. The active period is focused on burning calories.
