How 7 different actors' workout routines got them ready for intense movie and TV roles

Actors’ training programs aren’t one-size-fits-all. Stars work with Hollywood trainers to customize their fitness regimens depending on the movie and role they’re getting in shape for. The customization gets down to the details, like Scarlett Johansson doing hip swivels to nail Black Widow’s signature leg-wrap move or KJ Apa working on his V cut for Archie’s shirtless scenes in “Riverdale.” From Michael B. Jordan getting jacked for “Black Panther” to Jennifer Lopez learning to pole dance for “Hustlers,” see how each actor tailored their training program to their specific character. And see how celebrity trainers like Alex Fine and Jason Walsh helped their star clients achieve their desired results, working towards the actors’ physical goals, as well as their aesthetic, mental, and psychological goals.
