Which of the following is a recommended frequency for aerobic exercise for adults?

The recommended frequency for aerobic exercise for adults is at least 150 minutes per week. This guideline is supported by many health organizations, including the American Heart Association and the Centers for Disease Control and Prevention, which emphasize the importance of regular aerobic activity in promoting overall health.

Engaging in 150 minutes of moderate-intensity aerobic exercise per week is associated with numerous health benefits, including improved cardiovascular health, better metabolic function, weight management, and enhanced mental well-being. The duration allows for a sustainable approach to fitness that can fit within a variety of lifestyles while also promoting consistency and adherence to an exercise regimen.

The other options suggest either insufficient amounts of exercise or an impractical frequency. For example, while 75 minutes of vigorous activity per week is beneficial, it is generally regarded as a minimum recommendation, not the primary goal for overall health. Additionally, daily workouts lasting 90 minutes or a once-a-week session for 120 minutes may not be feasible for many individuals, which could lead to lower overall adherence to a regular exercise program. Thus, the 150 minutes per week strikes a good balance, making it a practical and effective target for adults striving to maintain their fitness.
