Stairway to where?

Make a New Year's resolution to boost your fitness? Let us present National Take the Stairs Day. (You're welcome.) The annual event began informally in 2016 and was later adopted by the American Lung Association. It's an ingenious way to nudge people to exercise—most of us encounter stairs during our day, so there's really no excuse. Climbing stairs is a low-impact activity that raises your heart rate and burns calories.
