Mark Wahlberg has played many roles. He's been a detective, boxer, and even a bodybuilder in the recent film Pain and Gain. To play these parts, Wahlberg always has to look the part. Luckily, he's a heavyweight actor who loves to lift heavy weights, so he never fails. He just trains with unmatched intensity and hardcore dedication, and we've got the workouts to prove it.

Mark Wahlberg Project Pain & Gain

Wahlberg's personal trainer, Brian Nguyen, says the action star is far more than a Hollywood hero. In Nguyen's eyes, Wahlberg is an elite athlete. "He's changed roles so many times, and each role creates a different starting point," Nguyen says. "I really respect him for the fact that as an athlete, he's able to bring himself to that level of intensity … for lack of a better word, to dominate."

Wahlberg may not have the time, multiple coaches, and locked training schedule of a pro athlete, but Nguyen says that Mark is undeniably part of the pro community. Wahlberg's mindset makes him a pro, Nguyen says. "You can't deny mindset," he explains. "You can't deny that variable of intensity, commitment, and pride."

If you think you've got what it takes to hang with Wahlberg, you'd better prepare for an all-out training assault. We've got two brutal muscle-building workouts Nguyen designed to pack slabs of lean muscle on Wahlberg for Pain and Gain. More strength and size are waiting for you at the end of each session, provided you can make it through. Wahlberg won't quit, but you might want to.
