Physical activity is any body movement that works your muscles and requires more energy than resting. Walking, running, dancing, swimming, yoga, and gardening are a few examples of physical activity. According to the Department of Health and Human Services' 2008 Physical Activity Guidelines for Americans physical activity generally refers to movement that enhances health.
Regular physical activity can improve the health and quality of life of Americans of all ages, regardless of the presence of a chronic disease or disability. For people who are inactive, even small increases in physical activity are associated with health benefits.
