PIC: See Mark Wahlberg's Sexy, Chiseled Body

Mark Wahlberg has always prided himself on maintaining a hard body, so he was more than happy to show off his hard work this week.

Out on the set of his upcoming flick Pain and Gain in Miami, the 40-year-old actor went shirtless while flaunting his chiseled pectorals, taught abdominals and bulging biceps.

From the looks of his toned body, Wahlberg hasn't been dining too frequently at his new burger joint, Wahlburgers, which he opened in Hingham, Massachusetts in October with older brothers Paul and Donnie.

Back in August, the '90s underwear model joked about how his days as a Hollywood heartthrob are dwindling down, thanks to a certain Twilight star.

"I'm sitting at a table with a gentleman who is better looking than you and is in better shape than me," Wahlberg told Leonardo DiCaprio during a speech at the Hollywood Foreign Press Association's luncheon in Beverly Hills. "So, we're both out of a job, dude. Taylor Lautner! We're screwed. It's over, dude. Titanic and Boogie Nights were a long time ago. I accept it. I had a good run and on to the next."

Tell Us: Do you think Wahlberg still has what it takes to be one of Hollywood's hottest men?
