One of the oldest known staircases in the world is in the Austrian village of Hallstatt. There, in the depths of an ancient salt mine, lies a staircase almost 3,400 years old. I mention this by way of noting that staircases have a long, long history, and have always been closely associated with humanity, providing excellent utility and plenty of opportunities to exercise.
Yes, exercise. While exercising on stairs strengthens and makes us more sure-footed on said stairs, it also provides a carryover effect that can make us stronger and more functional throughout the day.
