The movie Rocky has long since become part of American myth. If you have seen it and the theme comes on while you’re in the gym, you push a little harder. It’s become a universal symbol for working hard and triumphing. Proximity to the Bicentennial didn’t hurt.

That boxer was named Chuck Wepner, and he got into the ring with Ali on March 24, 1975.
