Physical Activity

Physical Activity

For improved health and quality of life, people must be active.

Physical activity is defined as “any bodily movement produced by skeletal muscles that requires energy expenditure.” Walking, playing with your dog, gardening, attending a fitness class – all these activities count towards health.

The opposite of physical activity, called sedentary behavior, is associated with chronic physical and mental conditions.

The good news? All Virginians can increase their physical activity and decrease their sedentary time. We hope to share resources and opportunities to help you get started and stick with it!

Virginia Cooperative Extension offers two evidence-based physical activity programs.



We offer an evidence-based, eight-week online program to promote physical activity and fruit/vegetable tracking.


We offer an evidence-based, eight-week healthy lifestyle intervention. This program helps older adults learn and engage in a strength-training practice with others in their group, aerobic activity is encouraged between session, and basic nutrition information is covered. LIFT is a practice- and research-adapted version of Strong Women, Strong Bones; Activity for the Ages; and Stay Strong, Stay Healthy.
