It may seem as if Carrie Underwood just gave birth her second baby (son Jacob, who arrived in January). She's still lamenting the fact that her figure hasn't bounced back as fast as she'd like. However, the superstar has a huge trek coming up, the Cry Pretty 360 tour ...and it's launching next month!

That said, there's no rest for this working mama, and she's ready to take on the challenge. If the thought of starting a tour a mere few months after having a baby seems daunting to the average woman, we're sure it does to Underwood as well—but she's mapping it out, taking one step at a time.

Underwood posted photos to her social medial documenting her start of rehearsals Monday (Apr. 1), showing fans that she's taking this seriously. "Gang’s all here. Great first day of rehearsals! Can’t wait for the #CryPrettyTour360," she captioned the series of shots. Underwood looks in fighting form, even dressed casually in all-black leisure wear for her practice runs.

She followed that up with a second post on Tuesday (Apr. 2), showing herself hard at work on "Rehearsals day 2," holding a guitar this time.

The "Love Wins" singer will set out on her Cry Pretty Tour 360 in the U.S. beginning on May 1 in Greensboro, N.C., and visit multiple cities through the end of October—including several dates in the United Kingdom during the middle of the summer. She'll bring Maddie & Tae and Runaway June out as opening acts for the duration of the U.S. leg.
