Which of the following is a known benefit of regular physical activity across life?

• A. Increased flexibility
• B. Lower rates of illness
• C. Lower rates of obesity
• D. All of the answers are correct

Answer: (D)

Regular physical activity across life produces a range of health benefits, not just one outcome. When you stay active, flexibility tends to improve because regular movement keeps muscles and joints supple and helps maintain a good range of motion. Activity also supports immune function and lowers the risk of many illnesses, contributing to lower illness rates over time. In addition, being physically active helps manage body weight and can reduce the risk of obesity, due to increased energy expenditure and positive effects on metabolism. Because each of these benefits can occur with consistent activity, recognizing all of them as known advantages reflects the broad, cumulative impact of staying active throughout life.
