Josh Duhamel Performs Uphill Sprints in Brentwood

Sprinting uphill on a sunny weekend day in Brentwood, Transformers star Josh Duhamel works on keeping his figure slender and toned.

Josh was also spotted with wifey Fergie of Black Eyed Peas fame heading for the Supercross, where they both sported his and hers biker-inspired fashions. How cute!
