At 80 years old, Ernestine Shepherd, is known as the world's oldest body builder. She told Judy Hsu what inspired her to get on the path to fitness.

"My sister and I didn't like the way we looked in bathing suits. So after that, we said 'we got to get fit!' So we started going to a gym and working out. That started the whole thing. At that time, I was 56 years old," Shepherd said.
