Jennifer GarnerJennifer GarnerTo look at Jennifer Garner it's hard to believe she had a baby less than a year ago.

But the Alias beauty has been sharing her post baby programme which helped her get back into fine fettle.

And the key is...

Breastfeeding. Thats right, forget your trainers, make yourself comfy and mother your way back into skinny jeans.

Jen insists that it's just this that helped her slim down after childbirth, because she had no intention of abandoning her daughter to hit the gym.

Jennifer, who's married to Ben Affleck, gave birth to Violet last December and is keen to put her family first.

The 34 year old said: "(I lost weight) breastfeeding! That and moderate exercise and an eating plan with the help of my personal trainer.

"I am more concerned about keeping healthy and spending time with Violet than anything else"

Good for you Jen.
