Use this video to pace yourself for this 10-minute workout.

The New York Times - December 10, 2014: A new study indicates that just 1 MINUTE of high-intensity exercise can very quickly make a big difference to your health and fitness, especially if you are sedentary.

If you have just 10 minutes a day for a quick routine, follow this workout. It calls for you to do slow and easy pedaling on a stationary bike, interspersed with just 3 quick intervals of 20 seconds each, during which you pedal like bloody hell, absolutely flat out.

And the exercise doesn't have to be cycling: you can do this on an elliptical machine, you can sprint up stairs in 20-second bursts, or even run hard in place.

Do this three times a week, and in one month, you'll be in way better shape -- significantly increased endurance, blood sugar down (males only), diabetes risk down (males only), resting pulse rate down, weight probably down -- it's a huge payoff for the small effort you'll invest.
