Hilary SwankHilary SwankHilary Swank has a bod that makes us rather green around the gills. 

And she thanks her lucky stars for it.

Cos it seems that it is down to her rentals.

She told People: "I think I've been blessed with my father's metabolism."

Which is always gonna help - but don't go getting in a humpf thinking it's so unfair.

Because she don't just sit on her slim backside.

She works at her toned figure too.

And it seems she rather hearts feeling the burn.

Go figure.

She added: "I really appreciate exercise because I think it's a great stress relief.

"I do this thing called power pilates, which I love, love, love."

Yet at the end of the day it's Dad who gets the credit: "I try and get out as much as I can.

"But I think in the end I really have to give it up to my genes."

Lucky lady.
