Carrie Underwood is "empowered" to be a better mother when she works out.
The 'Before He Cheats' hitmaker says exercise makes her feel like she can be a better mother to her three-year-old son Isaiah.
She said: "When I workout it's empowering. I feel like it allows me to be a better mom, and a better wife and a better daughter - and I feel good."
Carrie likes to "switch things up" when she works out rather than doing the same thing all the time.
She added to People magazine: "I like to switch things up. I actually workout with Eve [Overland - her trainer] via Skype quite a bit, because she lives in Atlanta. She's really great - she tells me what to do, and we've done all this stuff before I could do that [refers to the group workout]. I like to run when it's warm outside. If it's a nice day I like a little sunshine - it makes me feel good.
"I love doing weight training. We don't do anything too crazy. I feel like everyone is always looking for that bandwagon type workout - whatever the hot class is. We just do a lot of basic stuff. We do pushups, and pull ups and curls and squats and lunches. All those kind of basic things - they work."
And the 35-year-old singer has confessed she secretly "competes" against other gym goers.
She said: "I love just putting headphones in and going for a run. I feel so good when I get home, especially when it's hot. I'm one of those weirdos that likes to run when it's super hot outside! Or classes. I find myself competing with other people in the room. I'm like, 'Oh she's good, I want to be like her!' I try to 'beat' someone in the class. They have no idea we're competing!"
