The 4 Minute Workout: High Intensity Training Really Works

I have written several times in this blog about the potential health benefits of High Intensity Interval Training or HIIT. That approach to fitness involves cycling or some other aerobic activity for a short period of time (as little as 30 seconds) followed by a rest period.  This procedure is repeated three or four times, three times a week. It works as evidence has shown.

There is a new twist on high intensity training that deserves a further look. We all complain that we never have enough time to exercise. We are too busy at work, at home and everywhere else to make it to the gym for an hour workout. Well, you may only need four minutes, three times a week to achieve similar results. And you can do it anywhere and no special equipment is required

As reported in the New York Times, "The 4 Minute Workout", researchers at the Norwegian University of Science and Technology conducted a study to determine whether 4 minutes of  aerobic exercise at 90% of maximum heart rate performed three times a week would have the same effects on maximal oxygen uptake, blood sugar and blood pressure as longer training sessions. After ten weeks, the researchers determined that the answer was a definite "yes."
