These Instagram Famous 'Fit Moms' Dealt With Backlash for Sharing 'Six Pack' Pregnancy Photos

— -- Nothing will prevent Stacie Venagro from getting to the gym – not even pregnancy.

The 31-year-old personal trainer has spent much of her life training for fitness competitions and she was crowned Miss World Pro three times.

Now she has become famous for being a so-called "fit mom."

She is part of a group of mothers and mothers-to-be on Instagram who have gained social stardom for their highly ambitious workout routines – with or without a baby on board.

"They're working out, whether it's walking everyday or doing Crossfit everyday. That's what a ‘fit mom’ is," Venagro said.

Venagro, who gave birth to her first child, Aidan, in March, said she worked out for the full duration of her pregnancy up until the day she gave birth.

“I was fit beforehand so my doctor had told me do what you can do but do not strain,” she said. “You know your body best, you know when you can work out and when you can’t. So I consistently worked out, every single day.”
