"Sometimes you have to work your baby into your workout...but that's ok because the world is your playground!" Underwood wrote, adding the hashtags "#MonkeyBars," "#WorkoutAnywhere," "#StayThePath" and a link to CALIA by Carrie, the singer’s line of fitness lifestyle apparel.

Underwood shared a look at her workout, including jogging with her stroller and monkey bar pull-ups. The hard work is clearly paying off as the country singer stunned at the CMT Awards back in June and looked hotter than even in her new music video for "Smoke Break."
