I'm in good shape. To some people, it's a bit of a mystery how I'm much more physically fit than they are. They know I go to the gym, but, hey, they go to the gym sometimes, too, so what's the deal? Here's the secret:<p><i>I work really, really hard.</i><p>When I go to the gym, I push myself as far as I can take it mentally and physically that day. Some days it's more than others. But overall, I work much harder in the gym than most people I know.<p>Treat your exercise time as something to excel it, not a chore to do. It can make a world of difference.
