How Natalie Portman Trained for Her ‘Thor: Love and Thunder’ Transformation: Workout Secrets From Her Trainer

Mightier than ever. Natalie Portman‘s Marvel character Jane Foster returns as a superhero in Thor: Love and Thunder, so she hit the gym harder than ever to make sure she looked the part.“We trained for 10 months, starting around four months prior to filming,” Portman’s trainer Naomi Pendergast exclusively told Us Weekly. “Natalie did five sessions a week and did not miss one session for the whole time period we trained.”The actress, 41, returned to the Marvel Cinematic Universe for the fourth Thor film after learning that her scientist character (who broke up with Chris Hemsworth‘s titular hero offscreen before Thor: Ragnarok) had an impressive story that includes her turn as superhero after she gets ahold of Mjölnir, Thor’s magic hammer.

When Jane transforms into The Mighty Thor, she gets long blonde hair and buff arms along with some superpowers. While the CGI team could handle the flying and super strength, Portman was responsible for Jane’s buff body.“I was asked to get as big as possible.

That’s an amazing challenge — and also state of mind as a woman,” the Academy Award winner told Variety last month.“The initial goal was to build arm and abdominal definition,” Pendergast explained to Us. “We also worked on stability and agility for injury prevention as Natalie had some dynamic stunt scenes that required her to move, twist and land in various positions. … I was also really pleased she got through the challenging stunt process without any injuries.”Portman — who shares son Aleph, 11, and daughter Amailia, 5, with husband Benjamin Millepied — never tried to lose weight during the process, but she still had to pay attention to calorie intake.
