What is HIIT?

High-intensity interval training is a fitness option that involves a cycle of repeated rigorous workouts and resting sessions. It is a type of cardiovascular exercise that may involve the use of treadmills, rowing, or jumping rope. As the name implies, HIIT involves intense challenge that makes you sweat fast and with a resting time for a slower recovery, which is then followed by another round of high-intensity challenge. The preference for your work and rest period would depend on your capacity and this can vary from a rest of between 6 seconds to 4 minutes after a rigorous workout of about 15-20 minutes. If practiced frequently and consistently, HIIT can help improve your cardio health.
