Minimising Walking

When someone drives to the gym, do they try to park as close as possible to the entrance? Or are they pleased when only a distant parking spot is available, so they can get in an extra bit of exercise?  It struck me as contradictory that someone who'll be getting on a treadmill for 30 mins is reluctant to walk an extra few steps when they're not officially exercising. What brought this to mind is that I'll happily play sport for ten hours a week, but I'll still activate my brain's navigation computer in order to calculate the shortest walking route wherever I'm going. Is there any logic to that?
