Lockdown hasn't stopped Carrie Underwood for continuing with her grueling fitness regime. 

And the country singer proved her hard work has paid off when she stripped down to her bikini on Saturday morning. 

The 37-year-old flashed her toned abs in a bright and colorful selfie for her nine million followers.

'Is it summer yet? ☀️ #PoolReady #ChooseYou,' she captioned the photo.  

Carrie opted for a Hawaiian style bikini top with a floral design. She teamed the look with a pair of rose red colored bottoms. 

But it was the mom-of-two's toned mid-section that stole all the attention in the happy shot.

Clever: The husband of Mike Fisher and mother to Isaiah, five, and Jacob, one, 'sneaks in exercises when she can or just as she moves about in her everyday life,' said the trainer

Carrie accessorised with a floppy wide brimmed hat that shielded her face from the sun. 

Her blonde hair was styled out naturally and she appeared to be wearing a natural face of makeup, complete with fake lashes, a subtle shadow and blushed cheeks. 

Carrie's post comes after her trainer, Eve Overland, revealed to Us Weekly earlier in the week that she will even workout while doing laundry. 

'She is dedicated to living as healthy as possible the for 52 weeks of the year,' she said. 

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