Carrie Underwood sees fitness as her "therapy".
The 'Before He Cheats' hitmaker doesn't like massages or facials and if she wants some time away from it all, she just hits the gym.
She said: "I feel like it's my therapy everyday. I don't go get massages, I don't go get facials. That would be great. I might get a massage twice a year - some Mother's Day present or something, which I literally have a gift card for that, that's like two years old that I have not used for Mother's Day. But, that's my thing. I don't need vacations even. I'm like, 'Honey, you can give me like an hour, I'm good. You don't have to take me out. It's fine.' That's kind of my therapy. I feel like a lot of what I do is physically demanding."
And the 35-year-old singer finds it "demanding" being on stage, especially having to sing and dance around in heels.
She added to PopCulture.com: "It is demanding being on stage, and especially some of the songs that I write and sing are really hard, and I need that. I need to be at my peak. I need to be able to sing and walk across the stage without being winded. And I'm doing it in heels, which makes it five times as hard, so I feel like that's just something that makes me a better person, a better performer. It just makes me feel better about myself. It makes me feel better. I need that in my life."
