Which statement best describes the aerobic activity guideline pattern for health benefits?

• A. 150 minutes per week of moderate-intensity aerobic activity
• B. 30 minutes per day only on weekdays
• C. 10 minutes per day, with no weekly total
• D. 120 minutes per week of vigorous activity only

Answer: (A)

The essential idea is that health benefits come from reaching a weekly amount of aerobic work that you can spread across days. For most adults, the guideline is about 150 minutes of moderate-intensity aerobic activity per week. Moderate intensity means you’re noticeably working harder than resting but still able to talk in phrases, like brisk walking. The pattern is flexible: you can do roughly 30 minutes on five days, or break it into shorter sessions of at least 10 minutes that add up to 150 minutes for the week. If you prefer higher intensity, you can substitute vigorous activity, but the weekly total of effort should align with that moderate-equivalent target.

Among the options, 150 minutes per week of moderate-intensity aerobic activity best captures this standard pattern for health benefits. The other choices either misstate the weekly total, limit the pattern to weekdays, or specify a different structure that doesn’t reflect the commonly recommended weekly total, flexible distribution, and moderate-intensity emphasis.
