Why To Exercise Today: Even Just 15 Minutes May Help Your Heart

It’s kind of a tricky health message to calibrate: The guidelines say you really should try to get in at least 150 minutes of moderate exercise a week, or 75 minutes of high-intensity. But even less than that is better than none.

Today we focus on the minimal rather than the optimal. As USA Today reports here:

More research shows that even small amounts of aerobic exercise help lower coronary heart disease risk, according to a review published Monday in Circulation, the journal of the American Heart Association.

The mega-study is part of a growing body of research showing that some physical activity provides health benefits — even when levels fall below the recommended federal guidelines of 150 minutes of moderate-intensity physical activity a week…

“The biggest health benefits we saw were for those who went from doing nothing to those doing something small,” says Jacob Sattelmair, author of the new AHA study. “Even a little bit of activity makes a significant difference.”

A little bit means 10 to 15 minutes a day. Sattelmair says the new findings are the first to make quantitative assessments of the amount of physical activity a person needs to reduce risk.
