Face it -- you aren't going to be losing any weight by riding around in a golf cart. It isn't going to happen. You'll most likely be drinking and breaking the 90 degree rules (As my uncle says, "You're always 90 degrees away from something") and eating a hot dog at the turn.
But walking ... walking can burn some calories. You can lug your bag or use a pull-cart and the three mile trek is good enough for a solid exercise. Well, unless you get your hands on the Mantys Golf Caddy.
I mean, this is America, and we cut corners more than a fourth-grade art class. You can "walk" 18 holes without walking at all! Next up -- Sumo wrestler just carries you to your ball.
