Which includes one component of the minimal amount of regular exercise and physical activity you need to reap important health benefits?

• A. 75 minutes of moderate-intensity aerobic activity every single month
• B. 150 minutes of moderate-intensity aerobic activity every single week
• C. 150 minutes of moderate-intensity aerobic activity every single month
• D. One day of strength training a month

Answer: (B)

Regular, moderate-intensity aerobic activity accumulated over the week provides health benefits, and the minimal amount typically recommended is 150 minutes per week. This can be split into practical bouts, like 30 minutes on five days, making it easier to fit into daily life. Moderate intensity means you’re working hard enough to raise your heart rate and breathing but can still carry on a conversation. The other options don’t meet this weekly target or frequency: far too little activity is planned, or the activity is concentrated in a single month rather than spread across the week. For a fuller picture of health benefits, include muscle-strengthening activities on additional days as well, but the shown amount of aerobic time per week is the best fit for this question.
