If you're not a treadmill fan, you can work sweat in the bedroom: The researchers determined that sexual activity is a moderate-intensity aerobic exercise that burns about 3 calories per minute in women. And like any aerobic exercise, sex can help strengthen your heart, lower your blood pressure and reduce your risk of type 2 diabetes.
But that does not mean you should give up your usual workout routine. "Sex is a low-impact exercise for the most part, and, on average, has been equated with walking only one mile in 20 minutes," says Alfred Casale, MD, a cardiologist and associate chief physician at Geisinger. And the American Heart Association recommends 150 minutes of moderate exercise each week, so unless you feel particularly dashing, you will still need to put on your sneakers a few times a week.
