<human>:  I heard about a new exercise trend that could help me lose weight. What is it and where can I find more information about it?
<bot>: The new exercise trend is called High Intensity Interval Training (HIIT). HIIT combines short bursts of intense exercise with recovery periods of lighter exercise. The aim is to help you burn more calories and lose weight more quickly than with more traditional aerobic exercises. You can find more information about HIIT on fitness websites, as well as in books and videos that cover the subject in more detail.
