Question

explain the difference between physical activity and exercise.

Explanation:

Physical activity is any bodily movement produced by skeletal muscles that requires energy expenditure, e.g., walking, cleaning. Exercise is a subcategory of physical activity; it's planned, structured, repetitive, and purposeful for improving or maintaining physical fitness (e.g., running workouts, weightlifting sessions). So physical activity is broader, exercise is a deliberate, structured type of physical activity.

Answer:

Physical activity is any bodily movement (e.g., walking, cleaning) using skeletal muscles and expending energy. Exercise is a planned, structured, repetitive physical activity (e.g., running workouts, weightlifting) aimed at improving/maintaining fitness. Physical activity is broader; exercise is a deliberate, structured subset.
