And now it's time for all of us to feel really, really lazy and out-of-shape.  73-year-old Ernestine Shepherd of Baltimore is a grandma, goes to church regularly . . . oh, and she's the Guinness world record holder for the world's OLDEST female bodybuilder. 

Here are some of the craziest facts about her:
She didn't start exercising until she was 56. 
She wakes up at 3:00 A.M. every morning (--literally a full HOUR before everyone else her age) to run and lift weights.
She runs 80 miles per week and does 5Ks in about 28 minutes (--for about nine minute miles).  She's also finished EIGHT marathons.
She bench presses 150 pounds . . . about 30 pounds more than her body weight.
She's been married for 53 years and has a 13-year-old granddaughter.
She won a bodybuilding contest in 2008, beating many much younger women.
According to a former Mr. Universe, Yohnnie Shambourger, quote, "She's special because no one can have that kind of muscle at her age."
She doesn't take any supplements because she doesn't know what they'd do to her "old body."
Her idol is SYLVESTER STALLONE in "Rocky" and her dream is to personally train MICHELLE OBAMA.
