Can you believe this Australian woman is a 70-year-old mother of three?

Meet Carolyn Hartz from Australia.

You would not believe it from looking at her, but she a mother of three.

And is 70 years old. Yes, you read that right.

She boasts a bikini body and great skin that women who are two or three times younger than her dream of.

Ms Hartz says she was once addicted to sugar, but has not eaten it in the last 28 years, report The Daily Mail and AcidCow.

She says though it may be more difficult for women to stay in shape past the age of 40, it is possible "if you really want to work for it".

Ms Hartz follows a strict diet, exercise and work routine.

She also tries to get eight hours of sleep a day.
