1. She Prioritizes Her Health

“Over the years I’ve realized that if you don’t have your health, you’ve got nothing. So that comes first,” she told Women’s Health. “And how do you get that when you have two little kids, and a husband, and a lot of work? I work for balance now. I do yoga, and I run, and I meditate. I take really good care of myself and I eat well.” She also loves to spin.

2. She Follows the 80-20 RUle

Nicole eats healthy most of the time. “I go out on the tour bus [with Keith]. There’s a lot of junk food on the bus...I’m just not someone that believes in denial. It’s walking a path that’s ultimately 80 percent healthy, 20 percent…sometimes it falls to 70. But that’s why I think you have things like natural health remedies—you find out what works for you. And I do a lot and I have a lot of energy,” she told Women’s Health.

3. She Enjoys Running

“I come from a marathon running family so that’s been part of my life since I was a little girl. I would get dragged out of bed by my dad… and he would just make us ran laps of the oval,” she told Women’s Health. “I just put my music on and off I go. I go into the woods and that’s why I love living in Nashville. And in Sydney you’ve got the beach, which is absolutely beautiful to run on.”

4. She Takes Yoga Classes

Nicole is a big fan of yoga. “I don’t like doing it at home. I like to go to class. I like to be around people,” she revealed to Women’s Health. “I do ashtanga. I like vinyasa, too. It’s very good if you run. For the IT band, you know. You need all that and, particularly as you’re getting older, you need to do the things that are not high impact.”

5. She Meditates

Nicole has been meditating since her teenage years, when her mother was diagnosed with cancer. “I try to do 20 minutes pretty much every day. And if I can do 20 in the morning and 20 at night…that’s my goal,” she told Women’s Health.

6. She Takes a Multivitamin

Kidman revealed to the Los Angeles Times that she is a big fan of supplements. “I take a Swisse multivitamin daily, which helps fill any nutrition gaps I have when I'm on the road,” she said.
