Hollywood's Fittest Celebrity Couples
Fergie and Josh Duhamel
Prior to Fergie's pregnancy, the couple could often be seen hiking in the Hollywood Hills. "I work out four times a week," Fergie told Rachael Ray in March 2012. "I get bored, so like I hike outside and I walk uphill to squeeze those glutes, put on music, jump rope -- with a double sports bra! A double sports bra is key for the jump rope."
