Physical activity is best described as any movement that leads to energy expenditure. This encompasses a wide variety of activities beyond just structured exercise, such as walking, gardening, household chores, and even playing with children. The key aspect of physical activity is that it involves movement, which uses energy and contributes to overall health and fitness.

Focusing solely on structured exercises or competitive sports limits the understanding of physical activity, as it excludes many forms of movement that can also promote health. Engaging in daily activities that require movement can be just as beneficial for one's physical and mental well-being. Therefore, recognizing that physical activity includes any form of movement reinforces the idea that individuals can incorporate more activity into their lives in diverse and accessible ways.
