Mark Wahlberg's 'Pain and Gain' Workday

Shooting scenes for his latest film, Mark Wahlberg was spotted on the set of "Pain and Gain" along with co-star Dwayne Johnson in Miami, Florida on Wednesday (May 30).

Keeping his hands on his hips, the "Contraband" actor peered across the set through a dark pair of aviators while talking to Anthony Mackie, and looked even more buff under his black tee-shirt after getting a spray tan on his hotel balcony on Tuesday.

Mark joins Dwayne and Anthony for the crime filled movie, "Pain and Gain" which follows a pair of bodybuilders in Florida who get caught up in an extortion ring and a kidnapping scheme that goes terribly wrong.

Although the soon-to-be 41-year-old had to bulk up considerably to play the role as a bodybuilder, he supposedly was able to pack on the muscle the natural way as sources tell Us, "Even though the film is about steroid abusing gym rats, he took it as a personal challenge to get to the size he is at now and has been training non-stop," adding, "And The Rock just inspires him to work harder."
