When you’re Carrie Underwood, staying fit is part of the job. But instead of going to the gym while she’s on the road, the singer is taking the gym with her.

Underwood posted a photo on Instagram of her new mobile gym, complete with an elliptical machine, weights, leg presses and more — something Tim McGraw recently established for himself, as well. Underwood says she’s “super excited" about the new fitness center on wheels, which will come in handy as she launches her Storyteller Tour later this month. The tour runs through May 30, a perfect ending to her “#ShreddedBySummer” goal.

The country star has been making fitness a priority even after the birth of her son Isaiah, regularly posting photos of workouts. She's had to get creative, like her squat technique using baby Isaiah for some added resistance. The “Heartbeat” singer also has her own fitness wear line called Calia by Carrie.

“Fitness to me — I’ve been vocal about it over the years — is a lifestyle,” she says about the brand. “I just love how I feel when I feel good about myself. There’s definitely a lot of me in the Calia line.”

Underwood's toned legs may be the most coveted in all of music, and she says she goes to great lengths to get in extra steps during the day and make sure she counts them all using her Apple watch and Fitbit.

“The worst is when I have to take them off during stuff. I’m like, ‘I’m gonna lose my steps!’ I’ll make other people wear them if I’m on set some place,” she explains, adding that she makes sure to use every opportunity to get those numbers up. “I’ll get on the phone and I’ll walk around the entire time I’m on the phone.”

Underwood’s Storyteller Tour kicks off Jan. 30 in Jacksonville, Fla.
