Recent headlines suggest that diet is more powerful in weight loss than is exercise -- but there are countless benefits from exercise beyond losing weight. Yet as a country, we drag our heels. Barely half of American adults meet recommended guidelines for aerobic exercise, far fewer than follow other health guidelines like not smoking and getting enough sleep. Today we look at a range of reasons to work out, from improving memory and sleep to warding off depression and extinguishing stress. We discuss the value of fitness trackers, and how to get back into a routine after an injury.
