1When it comes to exercise, less is not more—but it's certainly better than none.Physical inactivity accounts for as many as 23 percent of all deaths from major chronic(慢性的) diseases, yet there are so many people who spend a lot of time sitting down.Some people say that they have no free time for physical activity at all.

2Light activity can improve physical and mental well-being. While light activity is good,moderate (适度的) activity is even better, and health experts encourage everyone to have at least 30 minutes a day of moderate physical activity. But you don't have to head to a gym. As recent studies have confirmed, “lifestyle” activities, such as walking, house cleaning and gardening, are as effective as a structured exercise program in improving heart function, lowering blood pressure and keeping or losing weight.

3In one study, overweight middle-aged men and women who learned behavioral skills to make them more physically active, such as walking around airports or train stations while waiting for a departure, reduced their body fat percentage and improved their heart function as much as individuals participating in structured programs at a fitness center. In another study, fat women ranging in age from 21 to 60 who adopted a more active lifestyle lost as much weight as women in a low-impact aerobics (有氧运动) program,and regained fewer pounds in the following year.

4There are different levels and types of activity, like aerobics and muscle exercise,which are really helpful. Besides, short periods of exercise during the day are nearly as beneficial as one long session.
