What are the public health physical activity guidelines for adults?

• A. 60 minutes of moderate activity per week
• B. 90 minutes of moderate activity per week
• C. 120 minutes of moderate activity per week
• D. At least 150 minutes of moderate-intensity or 75 minutes of vigorous activity weekly, plus muscle-strengthening activities on 2+ days

Answer: (D)

Public health guidelines for adults emphasize both cardiovascular and muscular health. The recommended goal is at least 150 minutes of moderate-intensity aerobic activity per week or 75 minutes of vigorous-intensity activity, and to include muscle-strengthening activities on two or more days each week. You can mix and match intensity and accumulate the total in smaller bouts (even 10 minutes at a time). This combination targets heart and lung health while also building and maintaining muscle and bone strength. The other options underestimate the weekly aerobic time and omit the needed muscle-strengthening component, so they don’t align with the standard recommendations.
