Nicole Kidman performs an intense training session in Sydney

Nicole Kidman likes to stay in shape and is dedicated to her workouts.

And the 55-year-old, who has recently been spending time in Australia, was breaking a sweat on Wednesday while training in a Sydney park.

The actress looked completely focused as she put her toning muscles to the test using a set of resistance bands.

Nicole showed off her fit physique in trendy sportswear, including a purple short-sleeved T-shirt.

She added a pair of three-quarter length biker shorts in a navy hue and completed the look with sneakers.

The Big Little Lies star appeared to have minimal makeup on for the outing and her reddish-blonde locks were partly swept out of her face.

When it comes to working out, Kidman has always liked to stay active after growing up in a family that loved to run half marathons.

Years after her family participated in the popular City to Surf athletic event in Australia, Kidman now enjoys a mix of spinning, yoga and running.

Kidman previously shared her fitness tips during an interview with the Los Angeles Times, explaining, “Variety is the best way to [to become fit] I have found.’

She added: “If you think you’re going to wake up and run five miles every morning for the rest of your life, you’re going to get bored and hit the snooze button after a week.”

“So I try to mix it up with sports, running, yoga, and even just going for a walk with my husband and kids.”

In fact, the star is often seen sharing photos of herself enjoying runs, hikes, and horseback riding sessions on Instagram.

Although she has always been known for her trim and lean physique, the Eyes Wide Shut actress has long stated that she did not go on any diet, instead choosing to follow an 80/20 lifestyle.

“It’s walking down a path that is ultimately 80 percent healthy, 20 percent… sometimes it drops to 70 percent,” The Northman star admitted to Women’s Health in 2013.

The 80/20 diet is based on packing 80 percent of the diet with whole foods and allowing reasonable indulgence in the remaining 20 percent.

Kidman continued: “But that’s why I think you have things like natural health remedies: you figure out what works for you.” And I do a lot and I have a lot of energy.

Speaking to the Los Angeles Times in 2014, she again stated, “Actually, I’m not that strict about my diet.” I eat almost anything, but everything in moderation.

In another interview with Food & Wine in 2017, The Undoing star admitted that his favorite meal is a “fresh seafood platter with Sydney rock oysters, tiger prawns, mud crab and lobster.”

Her other favorite food, according to her 2015 73 Questions with Vogue video, is “homemade warm bread with Reggiano.”

The Others actress has also previously shared her love of an Australian dish called ‘sausage sizzle’, which is grilled sausage served on white bread.

In 2018, Kidman, who once said she could eat “just about anything,” revealed that she likes to eat live insects, including mealworms and crickets.
