For additional health benefits, how many minutes of moderate-intensity aerobic activity do healthy adults need per week?

The correct answer is 150 minutes of moderate-intensity aerobic activity per week for additional health benefits. This recommendation aligns with guidelines from reputable health organizations such as the American Heart Association and the Centers for Disease Control and Prevention, which suggest that engaging in at least 150 minutes of moderate-intensity exercise weekly can help improve overall health, reduce the risk of chronic diseases, and promote weight management.

This amount of activity can be broken down into manageable sessions, such as 30 minutes a day, five days a week. Regular aerobic activity is important for maintaining cardiovascular health, enhancing mood, and boosting overall fitness levels. An increase beyond this recommended duration can lead to further health benefits, but the baseline requirement for maintaining good health is set at 150 minutes.

The other options suggest higher amounts of activity, which are not the minimum guidelines for additional health benefits, thus making them less appropriate as baseline recommendations.
