He’s known as the fittest guy in Hollywood.
And Jake Gyllenhaal lived up to his name when he joined Man vs. Wild star Bear Grylls on a gruelling, two-day survival experience in Iceland for the hit show.

“You’ve got to smile when it’s driving horizontal hail and be able to face your fears and just get on and do it – and on both of those accounts, Jake came up strong.”
It's a little princess!
