Is there a difference between exercise and physical activity? Do I need both?

Exercise is actually a special kind of physical activity, and almost everyone needs both. Physical activity is any movement that requires energy, whereas exercise is planned, structured, and repetitive movements intended to improve or maintain physical fitness. It’s important to get regular exercise, and for most people that means 30–60 minutes most days of the week. That doesn’t mean you can just sit around the rest of the time, though. You need to be physically active in addition to your structured exercise routine. This could mean small activities during your workday that give you breaks from sitting. And when you’re at home, gardening, chores around the house, or taking the dog for a walk all contribute to a more physically active lifestyle!
