More exercise associated with longer lives

Adults who exceed the World Health Organization's (WHO) recommended weekly exercise targets live longer than those who don't, according to a new study published in the American Heart Association journal Circulation. The WHO urges adults to get 150 to 300 minutes of moderate activity per week or 75 to 150 minutes of vigorous activity. An analysis of 116,000 adults showed that those who reported 150 to 300 minutes of vigorous activity or 300 to 600 minutes of moderate activity (or an equivalent mix of both) had lower death rates over 30 years.
