Amber Heard underwent a grueling workout and weapons training routine to reprise her role as superhero Mera in the upcoming movie Aquaman and the Lost Kingdom.

And on Thursday, the 35-year-old actress displayed her sculpted abs and toned arms in a throwback photo that she shared on Instagram.

‘I know Kung fu,’ Amber wrote in the caption of the image, in which she was seen wearing an olive green sports bra and black leggings while holding a staff over her head.

The Drive Angry star beamed proudly in the snap as she stood barefoot on the blue floor of a gym.

In April 2021, the Never Back Down actress began prepping for the upcoming sequel to the 2018 blockbuster Aquaman and documented her workouts on Instagram.

Amber previously said that she exercised for up to five hours a day while getting ready to play the Atlantean queen in the first film.

In August, the mother of one posted a photo in which she was seen in the same leggings and sports bra as she laid on the floor following her training.

‘Another day at the office,’ the actress wrote in the caption.

Heard is reuniting with Jason Momoa for the next installment of the Warner Bros./DC Entertainment movie, which officially wrapped production yesterday.

Last year, fans of her ex husband Johnny Depp demanded that she be axed from the superhero franchise.

The former couple’s relationship has been laid bare following their very acrimonious split in 2017.

But while Depp was dropped from the Fantastic Beasts franchise over allegations of domestic abuse towards Heard, Aquaman producer Peter Safran told Deadline they had never considered replacing her.

Backlash: ‘I don’t think we’re ever going to react to, honestly, pure fan pressure. You gotta do what’s best for the movie,’ Safran told Deadline.com

‘I don’t think we’re ever going to react to, honestly, pure fan pressure. You gotta do what’s best for the movie,’ Safran said in July 2021.

‘We felt that if it’s James Wan, and Jason Momoa, it should be Amber Heard. That’s really what it was,’ Safran continued.

He added that the producers were, ‘not unaware of what is going on in the Twitter-verse, but that doesn’t mean you have to react to it or take it as gospel or accede to their wishes.’

‘You have to do what’s right for the film, and that’s really where we landed on it,’ Safran stated.

Stepped away: The ex couple’s relationship was laid bare following their very acrimonious split and Depp was dropped from the Fantastic Beasts franchise over allegations of domestic abuse

Fans started calling for Heard’s dismissal after her ex-husband Depp filed a libel lawsuit against the UK tabloid The Sun for branding him a ‘wife beater.’

Depp ended up losing that lawsuit, with the court ruling in favor of The Sun, which lead to the actor stepping away from his role as Gellert Grindelwald in the Harry Potter spin-off Fantastic Beasts 3, with Mads Mikkelsen replacing him.

Heard herself addressed the campaigns to get her removed from the film in November 2020, stating they had, ‘no basis in reality.’

‘Paid rumors and paid campaigns on social media don’t dictate [casting decisions] because they have no basis in reality. Only the fans actually made Aquaman and Aquaman 2 happen. I’m excited to get started next year,’ she said.

Aquaman and the Lost Kingdom is set for a December 16, 2022 release date.
