Carrie Underwood shows off her impressive six pack abs in a bikini

CARRIE Underwood showed off her impressive six pack as she posed in a bikini.

The country singer, 37, made sure she appreciated the sun in her newest sexy snap.

Carrie smiled at the camera as she wore a floppy hat and let her hair run loose over her shoulders in the pic to her 9 million followers.

The bikini was made of a tropical top with red bottoms.

She captioned the photo: “Is it summer yet? #PoolReady #ChooseYou”

Carrie’s abs impressed fans but these came with a lot of work for the mom-of-two.

Earlier in the week, Carrie’s trainer, Eve Overland, told Us Weekly that she works out while doing the laundry.

Eve said: “She is dedicated to living as healthy as possible for the 52 weeks of the year.

“Carrie has been known to do walking lunges around the house and jog in place while doing laundry.”

Eve also revealed her favourite workout is running.

The trainer continued: “When she hops on the treadmill or takes a jog outside inn the sunshine, it dials in her mind,” adding that it “gets her pumped for the day”.

Carrie is mom to sons Isaiah, five, and Jacob, one, with professional ice hockey player Mike Fisher.

The pair met backstage at one of her concerts in 2008 before getting engaged the next year.

They married in July 2010 in Georgia.
