Contrary to the claim of this Yahoo article, Ernestine Shepherd is not the oldest competitive female bodybuilder. But that is not the point.
The real lesson is, no matter how old you are, you can start, you can improve, and don't let some moron tell you what you can't do like lift heavy weights just because you are old. She started at 71yr. And i quote:
"if ever there was an anti aging pill, I would call it exercise...". Ernestine Shepherd.
Please note: the absence of flabby arms, dangling neck folds, humongous muscles (another myth), and what is probably visually unnoticeable: the presence of other chronic sicknesses.
