When Mary Lou Retton started in gymnastics, there weren't very many women in the sport who looked like her.
"Back in my era, gymnasts were pixies, slender, very graceful little butterflies ... I wasn't," the 48-year-old former Olympian told CNBC. "I wasn't a pretty, little gymnast. I was a very powerful, explosive gymnast."
At the 1984 Olympics, Retton proved her critics wrong when she became the first American woman to win an individual all-around gold medal in the sport.
That year she took home five medals. She was subsequently named Sports Illustrated's Sportswoman of the Year.
