part 2: what is the difference between physical activity and exercise?
physical activity is... exercise is...

Explanation:

For Part 1, we need to suggest more active alternatives to sedentary behaviors. Taking the stairs instead of the elevator increases physical activity. Engaging in outdoor games like basketball instead of playing video - games is more active. Walking to the store instead of driving a short distance is better. Taking a post - dinner walk instead of watching TV is a good choice. Parking further away and walking to the store adds steps. For Part 2, physical activity is any body movement that expends energy, like walking to the bus stop. Exercise is a planned, structured, and repetitive form of physical activity, such as a daily 30 - minute jog.
