Athleticism runs in my family.  My father played baseball, tennis, golf and whatever that sport is called when he chased down my boyfriends with a gun.  My mother was such a successful tennis player that at the age of forty she was playing on a college team and kicking girls butts half her age on the court.  So you can imagine that they both wanted their children to be fit little buggers.  Motivation from my father came in the form of either jumping out at us before dinner time and boxing us into submission or flat out chasing us away from any static position we assumed for more than an hour.
