Mark Wahlberg is not as tough as he thought, after struggling to complete the gruelling training for his upcoming role as an American footballer.

The screen hunk is determined to get his character in INVINCIBLE just right, and is working non-stop with a team from the National Football League (NFL).

He says, "I've been at camp with NFL guys and it's tough.

"We do it for four hours every day, the whole deal. I'm black and blue."
