What is the minimum weekly duration of moderate-intensity aerobic activity recommended for adults, and how many days of strength training are advised?

• A. At least 75 minutes per week with 1 day of strength training.
• B. At least 150 minutes per week of moderate-intensity aerobic activity, plus 2 or more days of strength training.
• C. At least 120 minutes per week with 5 days of strength training.
• D. At least 300 minutes per week and 0 days of strength training.

Answer: (B)

The question tests understanding of the minimum exercise guidelines for adults, specifically the combination of aerobic and resistance training. The standard recommendation is to aim for at least 150 minutes of moderate-intensity aerobic activity each week, plus strength training on two or more days. This balance helps improve cardiovascular health while also building and maintaining muscle strength and bone health.

Moderate-intensity aerobic activity includes activities where you can talk but not sing, such as brisk walking, steady cycling on level terrain, or water aerobics. You don’t have to do all 150 minutes in one block; future health benefits accrue when you spread activity across most days of the week, for example 30 minutes on five days.

Strength training should target major muscle groups on two or more days per week. Consistency here supports metabolic health, functional fitness, and injury prevention.

Other options either understate the aerobic duration, omit strength training, or propose an arrangement that doesn’t align with the paired emphasis on both cardiovascular and muscular work.
