Mark Wahlberg Bulks Up for 'Pain and Gain'

Mark Wahlberg has been pictured on the set of his latest film Pain and Gain looking much more muscular than usual. The actor revealed that he had to eat numerous times a day to bulk up for the new role. 

"I was eating 10 meals a day and drinking mass gainers. I was drinking my own. I created this line of supplements with GNC," Wahlberg said. "It was a lot of work. A lot of getting up at two in the morning to eat another meal and I was still full from the meal at 10 o'clock."
