At 59 years old, mum of two Josefina decided to take up bodybuilding - and she is still doing it now at 73 years old!
Josefina inspired millions with her charsmatic nature and body building performance to 'Pump It' by The Black Eyed Peas.
"I was hoping she comes in like a usual dressed up grandma and then drop her clothes and revel the muscles like a shock factor some people do. She is outstanding tho 😱" wrote one commenter.
"70 years and looks like this. I'm 23 and can't even wake up without aches." said another.
Watch the impressive performance above.
