What is the recommended exercise goal?

Guidelines for Physical Activity in Adults
Below is the Dept. of Health and Human Services recommendation for weekly activity from their Physical Activity Guidelines for Americans.  These guidelines are similar to the American Heart Association recommendations.

For substantial health benefits, do one of the following aerobic activities:

  • 150 minutes (2 hours and 30 minutes) each week of moderate-intensity aerobic physical activity (such as brisk walking or tennis)

  • 75 minutes (1 hour and 15 minutes) each week of vigorous-intensity aerobic physical activity (such as jogging or swimming laps)

  • An equivalent combination of moderate- and vigorous-intensity aerobic physical activity

    Adults should also do muscle-strengthening activities of moderate or greater intensity and that involve all major muscle groups on 2 or more days a week, as these activities provide additional health benefits.
