As of this writing, Portman hasn't divulged what her secrets are when it comes to getting jacked. Looking at her talk show appearances back in October of 2020, her arms weren't as huge as they are on the recent set photos, so clearly, she's put in some hard work quite recently. CrossFit coach, Maddy Black, of Vogue Fitness offered some of her insight to Ahlan Live into how Portman could accomplish such gains, and as she speculates, "Natalie will be carrying out lots of compound weightlifting movements such as squatting, pressing and pulling. In order to remain 'lean' for the role, she will be implementing some high intensity interval training into her weekly routine."
She goes on to explain how she would go about designing an exercise regimen for someone wanting the kind of arms Jane Foster's Thor has in the comics, declaring, "Weightlifting would form the foundation base whilst functional training would develop skills, improve flexibility and enhance endurance." We may not know exactly how heavy her weights are, but it's definitely clear she's been pumping iron in one way or another.
We didn't think there was any way Portman could look more intimidating than in her "Natalie Raps" video, but judging from those guns, she just proved us wrong.
