It’s no wonder Carrie Underwood’s legs are the most coveted of all celebrity stilts, now that we know what kind of workout she does on a daily basis. Underwood shared a selfie of her post-workout cool-down graciously provided by her dog, Penny, on Aug. 7, and underneath she listed her, well, extensive routine for the day.

We’re tired just reading it.

Underwood is a champion for fitness, regularly posting workout pics and encouraging others to get out there and exercise. She’s launched her own fitness wear line, Calia by Carrie, which includes everything from headbands to yoga pants. The tote bags even double as functional diaper bags, as the new mom demonstrated in another Instagram photo.

The artist is keeping busy, between mom duties to five-month-old Isaiah, selling out four shows in a row at the Grand Ole Opry, and signing on to host the CMA Awards with Brad Paisley this year for the eighth year in a row.

Underwood is currently working on new music for an upcoming album after celebrating her 21st no. 1 hit with "Little Toy Guns,” one of the new tracks on her Greatest Hits: Decade #1 record. There's no word yet on new song titles or a release date, but she has been spotted shooting a music video baring the results of that workout in Daisy Dukes in the California desert. Here’s hoping we see the finished product soon!
