"Don't deprive yourself of anything because eventually you'll crave it and then you might binge on it. Everything in moderation," Nicole told Women's Health UK. "For breakfast I love eggs and toast and smoked salmon or bacon, or porridge. For lunch I like maybe some soup or some sushi. For dinner, anything from pasta to rice, and meats and veggies, to sushi. When I'm going to indulge, I love pasta, pizza, I love Mexican with lots of cheese. I love French fries, or crisps – salt and vinegar crisps. In terms of snacks: almonds, coconut water, bits of coconut, baby carrots."

Nicole maintains variety with her workouts. "In a typical workout I would run on the treadmill, maybe 20 mins, then try to do some squats, some sit-ups on the exercise ball, some yoga stretches. When I'm home I like to take a spinning class called Soul Cycle or I like to do hot yoga – a modified version of bikram yoga – or hiking, and core power yoga in LA," she told Women's Health UK. And of course, she dances. "I mean, I heard that dancing and laughing gives you better abs than crunches anyway," she wrote in a recent post. 

Need a little motivation to exercise? Find a workout buddy, Nicole encourages. "Me and my girlfriends support each other for the gym. Because, you know, it's hard to be motivated sometimes, so when you go you push each other, – we try to do different things," she explained to Women's Health UK. "We'll go hiking one day and then we'll try a sculpting hot yoga class, then we'll do a cardio. We just motivate each other."

One of the secrets to Nicole's sensational figure? She burns calories even when she isn't officially exercising. Her Instagram feed is filled with photos of her active adventures, including walks, hiking, and surfing.  df44d9eab23ea271ddde7545ae2c09ec

Nicole exercises for both physical and mental health benefits. "I travel so much it's so important for me to sweat it out. It's not only for physical being, but mostly for my mental well-being. It keeps me centered, focused, strong and helps me get in the right frame of mind for my work ahead. Preparation is key. Prepare yourself so when the opportunity comes, you are ready!" she wrote on Instagram. 

Nicole gets enough sleep, even with her extremely busy lifestyle. "Get lots of sleep – sleep really makes such a huge difference," she told Women's Health UK.
