High intensity, that's the way to exercise

A HIIT workout can include a few types of strenuous exercises, some resistance exercises and brief rest intervals, just enough to catch one’s breath, in between.

In the movie Rocky, the boxer runs all over the city of Philadelphia to get fit. He’s there in the market, by the train tracks, by the docks and at the steps of the museum, panting away in his 1980s-style grey sweats and red headband. It’s an iconic image of exercise in that era.

I know many people who, like the fictional Rocky, run for miles and miles at a steady pace, believing this is an ideal way to get fit.
