Nicole Scherzinger forces herself to work out

London: Pop star Nicole Scherzinger says she forces herself to hit the gym. The 36-year-old singer said getting herself to the gym is getting harder as she gets older, reported Contactmusic.

"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 said.

However, the former Pussycat Doll - who is currently starring in the West End production of Andrew Lloyd Webber's 'Cats' in London - insists staying slender isn't the only reason she hits the gym.

"(Exercise) changes everything about how I approach my day and helps me go about life with confidence. 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."
