Adults need a minimum of 2 1/2 hours of moderate exercise per week, or one hour and 15 minutes of vigorous activity. And kids should get an hour of activity per day, according to the Physical Activity Guidelines for Americans.
Those are the numbers the U.S. Department of Health and Human Services came up with after a two-year process that included having a 13-member advisory committee review scientific research on the effects of physical activity and health.
