2. Exercise for about 30 minutes on most days of the week

Getting some regular, daily exercise can reduce your risk of heart disease. And when you combine physical activity with other lifestyle measures, such as maintaining a healthy weight, the payoff is even greater.

Physical activity can help you control your weight and reduce your chances of developing other conditions that may put a strain on your heart, such as high blood pressure, high cholesterol and diabetes.

In general, you should do moderate exercise, such as walking at a brisk pace, for about 30 minutes on most days of the week. That can help you reach the Department of Health and Human Services recommendations of 150 minutes a week of moderate aerobic activity, 75 minutes a week of vigorous aerobic activity, or a combination of moderate and vigorous activity. For even more health benefits, aim for 300 minutes of moderate aerobic activity or 150 minutes of vigorous aerobic activity every week. In addition, aim to do strength training exercises two or more days a week.

However, even shorter amounts of exercise than these recommendations can offer heart benefits, so if you can't meet those guidelines, don't give up. You can even get the same health benefits if you break up your workout time into three 10-minute sessions most days of the week.

And remember that activities such as gardening, housekeeping, taking the stairs and walking the dog all count toward your total. You don't have to exercise strenuously to achieve benefits, but you can see bigger benefits by increasing the intensity, duration and frequency of your workouts.
