Ooooh. Well that makes more sense. I was picturing the horror that would be running on an elliptical at the gym for hours on end. On a random side note, a coworker's sister was told by a trainer at her gym that women don't start burning calories when doing cardio until AFTER 45 minutes....at which time the workout actually begins. I called BS on it though and hopefully saved the poor girl from never-ending cardio.
