While he does like to stay in shape, he admitted he wouldn't want to have to stay in Rock shape.
"It's fun, I don't mind working out, I think it's pretty cool," he said. "It wasn't that intense — I'm not The Rock! If I was The Rock, I wouldn't wanna work out like that. It's a lot. It's too much, man."
However, he also admitted he could be coaxed back to the gym with the promise of a sequel... hinting that Atom Smasher might survive the first movie.
"I dunno maybe... if we do another one, maybe," he said. "Whatever comes from it, then I'd love to."
But he did also admit: "Bro I had cheat days the whole time!"
In "Black Adam" Centineo plays Atom Smasher — AKA Albert Rothstein — a member of the Justice League precursor the Justice Society of America, who can manipulate his molecular structure and manipulate his size and strength.
The big question is — is the film going to be any good?
"I think y'all are gonna like it," he concluded with a smile.
"Black Adam" is set for release on July 29, 2022 after suffering a 7-month Covid pushback.
