Since getting the part of Batman in the upcoming Man of Steel sequel that will begin filming this month, Ben Affleck has been working out to get his body to superhero status or so his personal trainer told the Twittersphere on Tuesday.

Nutritionist and fitness instructor Rehan Jalali was Affleck's personal trainer leading up to the filming of 2010's The Town, which Affleck starred in and directed, according to Superhero Hype.

Jalali took part in a Twitter Q&A on Tuesday and was asked what Affleck's workout goal was for the film. Jalali responded that the star wants to look like he's a real superhero.

"Big muscular yet lean and good body symmetry!" Jalali exclaimed. "Going for the Real-life superhero look!"

Jalali later added the following day that "Batman is getting Large! He's working very hard! #Dedication #Excited #DarkKnight #BatFleck #TheSixPackDietPlan."
