A HIIT workout typically alternates short intervals of high-intensity exercise and low- intensity or no exercise (aka rest). Whether you alternate sprints and walking, super fast jump roping with slow jump roping, or jump-squats and marching in place, the goal is to bump up your heart rate and then recover just enough to bump it right back up again. Rather than spend an hour a day walking, jogging, or running, the major appeal of HIIT is that you can get more done in less time. Interested in adding HIIT to your routine?
