Miami just got a little hotter -- Mark Wahlberg is in town shooting a movie and yes, he looks good.
The 40-year-old looked fit and fine when spotted on set of his upcoming flick "Pain and Gain" on Monday. Dressed in a white tank top and white-and-blue striped track pants, the father of four was seen doing crunches from a sit-up bar attached to the wall of a building.
"Pain and Gain" follows the story of two Florida bodybuilders -- Mark and Dwayne "The Rock" Johnson -- who get caught up in an extortion ring and kidnapping scheme. Ed Harris, Tony Shalhoub and Anthony Mackie also star in the film, scheduled to hit theaters next year.
