Zac Efron and Michelle Rodriguez Are Having the Most Active Vacation Ever

For most of us, vacation is all about lying out and soaking up the sun. That's not the case for Zac Efron and Michelle Rodriguez, who have been exploring Italy together this Summer. On Saturday, Zac and his businessman buddy Gianluca Vacchi hit the pavement for a workout in Porto Cervo in Sardinia. Looking fit in loose workout shorts and a tight Ramones shirt, Zac not only ran with weights but later stopped on a sidewalk for some push-ups.

Zac, Michelle, and Gianluca have taken to Instagram and Vimeo to share memories — including hot dance videos and several of Michelle's stunts — that the trio has created on vacation. In their latest video, Zac and Gianluca perform backflips off the side of a boat as bikini-clad Michelle captures the moment with her camera in the background. All the excitement comes a few days after their first boating excursion, during which Michelle flipped and jumped in a black bikini. There's no telling when the group's fun in Europe will come to an end: on Thursday, they popped up at an airport to jet off to their next destination.
