Now don't get me wrong - I LOVE TECHNOLOGY.
I am forever amazed at our human creativity and for right or wrong, our ability to innovate and drive technology further. I suspect it is our inherent human laziness that makes us want to do less and less.
When it comes to working out, however, I advocate never missing an opportunity to torch off a few calories.
USE THE STAIRS.
I am not talking about going up 60 flights to the office, if indeed that is what you do.
However, a few flights here or there, within reason, do add up. At my gym, I find myself going up and down from the 8th floor to the 5th or 6th and back again several times a session. They designed it that way. I call it the "Stairway to Heaven". I don't run up and down them (bad for the knees), but just walking up and down is it's own little extra helper.
Try to use the stairs whenever you can - it will help you get fitter faster.
See you in Heaven!
