Which of the following is NOT a benefit of regular exercise?

Regular exercise offers numerous benefits, including improvements in physical appearance, increases in functional capacity, and strengthening of blood vessel walls. The option citing weight gain as a benefit of regular exercise is correct because it is generally understood that regular physical activity is associated with weight management or weight loss rather than gaining weight. While there are instances where individuals may gain muscle mass leading to increased weight, this is a different context and is not typically a primary benefit attributed to exercise.

The general expectations of exercise include enhancing cardiovascular health, improving strength and endurance, and maintaining a healthy weight, all of which contribute to the overall well-being of an individual. Therefore, the assertion that regular exercise causes weight gain does not align with the commonly recognized benefits of a consistent exercise regimen.
