From the moment photos of Natalie Portman in “Thor: Love and Thunder” surfaced

This time around she is wielding Mjolnir, Thor’s Hammer, and she has the newfound power to throw lightning

The goal and initial brief for working with Natalie was to develop arm and abdominal definition

We started five months before filming and continued to train throughout the filming process to maintain her muscle

We worked on building her upper body three times a week, which included arm, back, chest exercises, boxing, skipping and running

The other two days were dedicated to injury prevention work, which included Pilates-based exercises

There were a few days after long stunt sessions where she pulled up a little sore in the wrists and neck

Once filming started, Natalie’s schedule was very busy so we would train early, around 4:30 a.m
