(You can walk off the weight in as little as 10, 20, or 30 minutes a day. Find out how with Prevention’s brand-new book, Walk Your Way To Better Health.)  Researchers from Arizona State University found that taking three 10-minute walks each day is a smarter strategy for blood pressure control than logging a single 30-minute session. The exercisers who did multiple minisessions not only reduced their systolic blood pressure during the day and evening (similar to the 30-minute group), but they also still saw reductions the following day. “Walking three times a day, even for a short period, reduces blood pressure after each instance, so you wind up with a longer-lasting reduction,” says principal investigator Glenn Gaesser, PhD. To reap the benefits, walk at a quick pace, as though you’re late for an appointment. For more ideas on sneaking exercise into your day, check out 25 Easy Ways To Fit In 10 Minutes Of Exercse.
