Dave Tate has an amusing post about HIIT here:
"I had someone call me last week and ask me why I do cardio the way I do. Why I do not do interval and sprint type training? He then said something I have heard many times before. He said, a sprinter is leaner than a long distance runner.
"so I said…
"Wrestlers are famous for their high volume long duration training and they are much leaner than a sumo wrestler who does explosive type training.
"A lineman is fatter than a receiver. Who trains with longer durations?
"Bodybuilders (even the natural ones) get leaner than any athlete and carry more muscle mass and very few do internal based training.
Makes a lot of sense. I find it humorous when people only select examples of athletes when it “proves” their point. (I could care less whether you think HIIT is better than long-duration cardio. I simply find amusement in these battle-of-the-anecdote type posts.)
