Is there a better way to get motivated into your bikini than with a running buddy? Uhhhh, no – especially if he’s a half-clothed hunk from a summer blockbuster!
Flaunting his bare pecks, Star Trek’s Chris Pine was spotted “trek”-ing his way through a hike in L.A. last week, while G.I. Joe: The Rise of Cobra star Channing Tatum (with his Fighting face on!) was snapped jogging shirtless through West Hollywood on Sunday.
So who would you want to get hot and sweaty with?
