If you want a workout to be a little more fun and a little less work, it's nice to have a friend.
For Hilary Duff
, that means going for hikes with her pups, and she did just that as an ambassador for Danskin's new Move for Change campaign
, which aims to foster women's health and wellness.
"I really hike, and I usually bring my dog," Duff says. "I live in a place that is crazy traffic all day, every day, and to be able to come into the mountain, hike and see other people – I really love that. I find that when I'm working out, I live a healthy lifestyle."
And it's true that Duff really gets moving with her pets. The actress frequently Tweets about the walks she takes with her five dogs: Dubois, Coco, Lola, Jak and Rue. So for her outdoorsy photo shoot with Danskin, Duff brought Dubois along, and they made their way up the L.A. hills together.
"He's a really good dog. He's a rescue so he's got his little quirks," Duff says of Dubois. "But he's a really good hiking buddy to have – he sticks it out with me."
