Why is it that when I walk up an escalator I get no where near as winded as I do when I walk up a flight of stairs. I understand that I'm moving up the incline faster on the escalator so I'm not exerting as much energy. I'm talking about walking up an escalator that's twice as long as a flight of stairs. I don't get it.
It's not important. I just started thinking about it as I almost fooled myself into thinking I was getting in better shape.
