Your health care provider may emphasize the importance of exercise, but exactly how important is physical activity for staying healthy?

Heart disease and stroke remain two of the most dangerous health problems in America, according to a recent review of statistics and research.

Exercising is a key part of staying healthy, but you don't always have to sprint to reap the benefits. New research shows that leisurely walking may have significant health advantages.

A stroke can be a scary, even deadly, medical emergency. But before this emergency strikes, there are several lifestyle changes that can help people lower their risk of stroke. Some regular exercise may be one of those changes.

Exercise until you sweat, and you can send your stroke risk running. Sweating during physical activity is a sign that you're getting an aerobic workout, and that can offer protection to your heart.
