Kellan Lutz has a body worth drooling over, and you can thank another set of droolers for making it happen – his dogs, Kevin and Kola.

“Walking both of my dogs is the biggest workout ever,” he told PEOPLE at the WWE and Creative Coalition’s Be a STAR event in L.A. on Thursday. I have these two leashes which I’m constantly twirling, and they zigzag! They are just all over the place. It’s a workout!”
