I'm all about HIIT. The only thing I see on here that specifies a HIIT workout is sprints though. And there's no need for insults, that was just straight unladylike of you. Also, this article was about 4 fat burning workouts, not the benefit of cardio and HIIT for athletic purposes.

Try being in the military without any kind of endurance training...some of us actually want to be cardio fit as well as strong.. If you don't want to do this, don't....but these are good workouts to just get the engine going. If you're not going to do them, why comment?
