: Is walking up the stairs a good exercise ? I'm planning to take the stairs ever day and was wondering if its a good exercise? There are 9 floors, with about 180 steps of 6 inch or 15 cm, so it would be a total of 1080 inch

I'm going to apply some really crude physics:

Gravitational Potential Energy (Joule)
= Mass (kg) * Gravitational Acceleration (g) * Height difference
(m)

Using some example values: 70kg * ~10m/s^2 * ~30m results in 21000 Joules. While that may seem a large number, converting it to kcal leaves you with a measly 5 kcal

So I'd have to conclude that while all small bits help, you'd have to walk the stairs more frequently for it to be a truly useful exercise.

There is more than one way to measure exercise. Yes the number of calories is low and to increase the number of calories would take a whole lot of climbing. The low level cardio and the psychological values of the exercise can far outdo the pure caloric count. Add to that the alternative of taking the elevator which will give you far less. What I'm saying is that you should take the stairs whenever possible, but don't use it as a primary exercise. Every little bit helps.
