Mark Wahlberg tucks in to new role

Mark Wahlberg was eating “ten meals a day” to bulk up for his upcoming movie.

The actor has already started shooting ‘Pain and Gain’, an action drama due out next year about a pair of bodybuilders who get caught up in a criminal scheme.

The Hollywood hunk said gaining muscle mass for his portrayal of a fitness pro was no mean feat. “I was eating ten meals a day and drinking mass gainers,” he told E! Online. “I was drinking my own. I created this line of supplements with GNC.”

The 41-year-old said it was tough to put on huge amount of muscles, but he enjoys changing his physique for his roles, adding the process is as much about the mental as the physical challenge.

“It was a lot of work. A lot of getting up at 2am to eat another meal and I was still full from the meal at ten o’clock,” he said.

“I like being able to change for parts, both physically and preparing mentally. It was a good time.”
