Speaking of slim, if you'd like to watch a bunch of overweight Americans work out and moan about their diets instead, there's always "The Biggest Loser" at 8 p.m. on NBC. (It had its season premiere last Tuesday.) We will attest that this is one of the best shows to watch while working out. Nothing will give you the motivation to stay on that elliptical an extra ten minutes than the sight of a 350-pound guy dragging a giant tire across the desert. Nothing!
