Too many people think you have to exercise really, really hard to get a benefit, and nothing could be further from the truth. You're actually getting probably 95 percent or more of the benefits when you're walking as compared to jogging." this according to Tim Church, physician and exercise researcher, Louisiana State University.
Going for a walk is the exercise Americans say they engage in most frequently, according to a Harvard poll. Most people who walk for exercise do so a few times a week. About a third say they walk every day. Even those that walk very little show tangible benefits on health — lower blood pressure, lower cholesterol, and an overall lower risk of heart disease.
