Even if we’re careful about eating healthfully, the best diet in the world can’t make up for a sedentary lifestyle. And boy, are Americans sedentary. We commute—usually by car—to our jobs, which are mostly at desks. But as these graphics show, a surprising amount of activity can be slotted into the average workday. Commuting by foot or bicycle can translate into an hour of calorie-burning, mood-lifting exercise. Moving more while on the job can help, too. Not everyone can be employed as a mail carrier, but we can take a lunchtime walk, choose the stairs instead of the elevator, or stroll down the hall to find a colleague, instead of emailing.
