Ernestine Shepherd, 74-Year-Old Bodybuilder, Inspires, Teaches Fitness (VIDEO)

Female bodybuilder Ernestine Shepherd is more than 70 years old and perhaps in the best shape of her life.

Shepherd dedicated herself to morphing "from a 'prissy' woman who never exercised to the Guinness Book of World Records' oldest female bodybuilder," ABC News reports.

As a result, Shepherd has received widespread attention and fans inspired by her story.

Shepherd said in a recent interview, she's up at 3 a.m. every morning: runs, lifts weights and works out other senior citizens at a local church in Baltimore. "I feel better than I did at 40," she said. "I am very, very happy."

Not only is she a bodybuilder and teacher, she's also a certified personal trainer.
