I'm sure many of us have been told to "Go take a walk' at one time or another, and that's good advice. In fact, a new study indicates that 10-minute walks can help those who may be at risk of developing high blood pressure.

Researchers from Indiana University in Bloomington say that taking four 10-minute walks at least an hour apart are more effective than a continuous 40 minutes on a treadmill. According to a report in "Reuters Health" shorter bursts of activity help to keep blood pressure low for three to four hours longer than a one-time long workout.

Sometimes the thought of a long workout can be tiring in itself, so maybe a few shorter exercise sessions in the day might be easier to take.

So, go take a few short walks during the day, and it's good for you.
