Pumping Iron

I never lift weights. Should I?
The New York Times suggests doing more than push ups and sit ups might be a good idea. Many elite athletes -- from rowers like Mark Flickinger to runners like Ryan Hall -- devote hours a week to strength training.
Nevertheless, not everyone believes getting huge means getting fast. When runners ask Kevin Hanson, a coach at the Hansons-Brooks Distance Project, about leg exercises, he responds: "You let me know if you think we are not working your legs enough. . . . There’s a lot more we can do to beat you up. But you don’t have to lift weights."
