i do it in the stairwell of my building. and i'm not running. I'm moving at about the same speed as everyone else. sometimes going downstairs i speed up a little, but not much. I think the real stairs are better than the machines because you UP and DOWN
Last night i went to the gym and got on one of those stairmaster machines.
according to it, i climbed 85 flights of stairs in 20 minutes!

Ok, that's what I thought. I can do this at home and use the stairmaster once in awhile.
