Heidi's new svelte figure is most likely down to her daily jogs.
She has been pushing herself to the limit running around the Big Apple this past summer in an effort to encourage people to get fit.

 

Heidi upped her fitness regime in for a challenge that she set on her website.
The supermodel signed up to the AOL Summer Run campaign to encourage people to get out and get fit.
She said: 'After running many miles, making lots of new running buddies, and pushing myself to the limit the Summer Run is over!
'But don't think that I'm going to stop all my new healthy habits just because I won't be tracking my miles anymore. And I hope you don't either!'
