What is HIIT?
High-intensity interval training (HIIT) has become a popular way to burn fat in the gym, but that's not all this type of cardio training is good for.
The essential framework of high-intensity interval training is always the same: Brief, all-out work periods, separated by rest periods that you wish were just a little longer. The work-to-rest ratio can vary from 1:1 (for example, 30 seconds on, 30 seconds off) to 1:4 or more, and the rounds can be just a few or 15 or more. But no matter how long you rest, the key is that you bring everything you've got to your intervals.
HIIT can be used to lose as much fat as possible while cutting, to stay lean and conditioned while adding muscle, or to improve aerobic and anaerobic endurance for performance-focused athletes.
