The role is undisclosed (although plenty of folks will confidently tell you she’s the new Wonder Woman – we’ll find out soon enough) but the effort is evident and the actress doing the work – Adria Arjona – is not only well known to Star Wars audiences, but very much appreciated for her unforgettable role as Bix Caleen in both seasons of Andor. Watch as she puts in the work to join the DCU (and who knows, maybe she’ll share the screen with her real-life partner Jason ‘Lobo’ Momoa).

In a new video for Women’s Health released on Thursday, Sept. 3, the Onslaught star broke down her workout routine while preparing for her mystery role in the upcoming Superman sequel, Man of Tomorrow. The 34-year-old joked that it’s a “horrible” regimen and people shouldn’t try it at home, but she’s been feeling stronger every day.

“I wake up. I do cardio for about 45 minutes,” she said. “Then I do weightlifting for about two hours. Then after the workout, I’ll have a bite to eat. We’ll box for six rounds and then I eat again. And then I eat and I eat and I go to sleep.”
