David Harbour Damn Near Ruined ‘Hellboy’ Bodysuit with Intense Workouts

EXCLUSIVE

David Harbour gave “Hellboy” producers one hell of a scare … he almost didn’t fit into his demon superhero bodysuit because he was too jacked!!!

Harbour’s trainer, Don Saladino, tells TMZ … Harbour’s 10-week workout regimen transformed him so much it set off a production panic. We’re told producers were actually upset over the weight loss and body reshaping.

Check out the vid … the celeb trainer says it wasn’t the case. He concedes, yes, Harbour’s body drastically transformed … but by packing on serious muscle. Nevertheless … Saladino says he had to have a talk with his client about actually NOT being too strict on his diet. Must be nice.

No doubt Harbour — proudly strutting a dad bod in “Stranger Things” as Sheriff Hopper — looks like a badass in the movie, released Friday.

BTW … most people who hire famous trainers usually request the Ryan Reynolds look. Not Harbour though!!! Now, about those abs …
