Still sporting the muscle he amassed for his role in Southpaw, Jake Gyllenhaal heated up the Italian coast while on vacation with his friend, Greta Caruso.

Wearing nothing but shorts and bushy beard, the star was looking ripped as he relaxed by the pool in Amalfi, Italy.

To get in shape for his role in the boxing flick, Gyllenhaal followed an extreme workout schedule – including 1,000 sit-ups a day, 100 pull-ups, 100 dips, two sets of 100 squats, jumping rope and running eight miles a day.

“That’s what I like to do – immerse myself in the world and soak up the molecules in the space that I train in, practice in,” said Gyllenhaal, 34. “I feel in general people’s fascination is on the physical, which I understand, but I also feel like it’s not why I do what I do.”

Accompanied by Caruso, who a source confirms is Gyllenhaal’s “longtime best friend,” the actor was taking some much-deserved time off after wrapping his next film, Everest.

Like Gyllenhaal, Caruso, 31, comes from a family of actors – she’s the daughter of CSI: Miami actor David Caruso and his second wife Rachel Ticotin.
