She's received rave reviews for her performance as Grizabella in the revival of Cats, and despite performing six days a week, has boundless energy.
Speaking exclusively to Cosmopolitan Body, Cosmopolitan's Health and Fitness magazine, Nicole Scherzinger thanks exercise for her positivity:
"[Exercise] changes everything about how I approach my day and helps me go about life with confidence – that's the main reason I do it. It gives me clarity and makes me feel stronger. It's not so much for the physical and vanity side of it. I do it more for the emotional and mental strength it gives me."
"Healthy for me means a healthy mind, then everything else becomes aligned – the mental physical, spiritual… everything… Being happy means having balance, being creative and finding peace."
However, she admits that working out isn't as easy as it used to be:
"I'm like any woman – my weight fluctuates up and down. I have good days and bad days. For many years I worked out every single day, but now I'm in my thirties it's like pulling teeth. I gotta make myself work out – you need to find that balance."
She admits being in London in the winter is a test of will power when it comes to eating healthily:
"I'm working with Sir Trevor Nunn, who used to be artistic director of the Royal Shakespeare Company, so I want to give it my all. But when I finish work it can be really hard to eat healthily – when it's cold you just want to eat a melted-cheese panini and soup. I'm going to turn into a cup of tea and a curry by the time I leave London! I eat differently in the UK from when I'm in LA. Over there, I'm happy eating a kale salad and sushi rolls but with this weather I've been eating a lot of curry. I do miss the sun in LA, but London inspires me in a different way. It's like being in a movie."
