Elsa Pataky, 46, shows off her figure in a bikini as she hits the beach with husband Chris Hemsworth

She works hard to maintain her gym-honed figure.

And Elsa Pataky showed off her incredible physique on Sunday as she hit the beach in Byron Bay with her husband Chris Hemsworth and two of their children.

The mother of three, 46, stripped down to a skimpy navy bikini while soaking up the summer sun with her eight-year-old twin sons Tristan and Sasha.

At one stage, Elsa went for a stroll along the sand with the family’s dog Sunny while Chris looked after their boys.

She later cooled down by going for a dip in the ocean with one of her twins. 

Thor star Chris, 39, also went for a swim in the surf, but concealed his muscular build under a blue rash vest and black shorts.

He protected himself from the hot Australian sun with a beige hat.

Elsa and Chris, who have been married for a decade, swapped the bright lights of Hollywood for a more relaxed life in Byron Bay nine years ago.

The Spanish actress previously said she enjoys the laid-back vibe of Byron, where she and her husband own a $30million mega-mansion.

‘We did the move three years ago and I’m so happy with it,’ she told Women’s Health in April 2017.

Chris recently announced he was taking a break from acting to spend more time with his family after discovering he was at risk of Alzheimer’s disease.

The Marvel Universe star told Vanity Fair he’d decided to take ‘time off’ after filming a confronting episode about death for his new Disney+ docuseries Limitless.

‘It really triggered something in me to want to take some time off. And since we finished the show, I have been completing the things I was already contracted to do,’ he said.
