Shape up, women!

 Las Vegas women are known for many things, but a healthy lifestyle apparently isn’t high on the list. Self magazine rates Bethesda, Md., as the No. 1 fitness city for women ahead of San Francisco and Honolulu.

  The worst city for women’s health? Detroit, followed by Gary, Ind., and St. Louis.

  What about the men?

  Well, that will have to wait for another survey.
