For aerobic benefits, how many minutes per week of exercise are recommended? How often should major muscle groups be addressed with resistance training?

a) At least 150 minutes; 1-2 days a week
b) At least 30 minutes; 3-4 days a week
c) At least 75 minutes; 5 days a week
d) At least 60 minutes; 2-3 days a week

For aerobic benefits, adults should engage in at least 150 minutes to 300 minutes per week of moderate-intensity aerobic activity or 75 minutes to 150 minutes per week of vigorous-intensity aerobic activity. Major muscle groups should be addressed with resistance training exercises on 2 or more days per week.

Explanation:

For aerobic benefits, the U.S. Department of Health and Human Services (HHS) recommends that adults engage in at least 150 minutes (2 hours and 30 minutes) to 300 minutes (5 hours) per week of moderate-intensity aerobic activity, or at least 75 minutes (1 hour and 15 minutes) to 150 minutes (2 hours and 30 minutes) per week of vigorous-intensity aerobic activity. This can be spread throughout the week. Engaging in physical activity beyond 300 minutes of moderate-intensity activity per week can result in additional health benefits.

As for resistance training, adults should address major muscle groups with moderate- to high-intensity resistance training activities on 2 or more days per week. These activities can include exercises like push-ups, sit-ups, squats, and weightlifting.
