Question: how many calories do you burn walking up 9 flights of stairs?
Answer: According to the MyFitnessPal app, you'll burn roughly 9 calories per flight of stairs, based on it taking one minute for a 150-pound person to climb a flight. (Obviously, your mileage, or should we say footage, may vary.) That might not sound like much, but depending on what floor you work on, it can add up.
