Meet 77-Year-Old Ernestine Shepherd, Competitive Female Bodybuilder And Marathon Runner

"Age is nothing but a number," says Ernestine Shepherd, the 77-year-old female bodybuilder who is taking the world by storm.

Having worked out almost every day for the past 20 years, she not only looks amazing but is the picture of perfect health.

"No high blood pressure medicine, no medicine for panic attacks, no medicine for acid reflux," she explains. "And by being out running and walking the depression and anxiety just left me." [sic]

Ernestine was declared the World's Oldest Performing Female Bodybuilder by the Guinness Book of World Records in 2010. (Edith Wilma Conner now holds the title.)

Since age 56 she has won two bodybuilding titles, as well as run nine marathons.

According to ABC News, Ernestine consumes 1,700 calories per day - including boiled egg whites, chicken, vegetables and a liquid egg-white drink.
