Carrie Underwood is having a bit of trouble getting her body back to where she wants it following the birth of her second child. The country star opened up about the struggle in a recent emotional post on social media.

As previously reported, Underwood and husband Mike Fisher welcomed their second child in January.

"Jacob Bryan Fisher entered the world in the wee hours of the morning on Monday," the 35-year-old shared at the time. "His mom, dad and big brother couldn't be happier for God to trust them with taking care of this little miracle!"

However, on Tuesday, the “Cry Pretty” singer posted an image on Instagram of herself in the gym along with a lengthy caption about the struggle to get her body back to what she perceives as normal.

“I’m going to be honest, ‘bouncing back, after having Jacob has been much more difficult than after I had Isaiah and I’ve been pretty hard on myself lately,” she wrote. “I go into the gym and I can’t run as fast or as far. I can’t lift as much weight or do as many reps as I could a year ago. I just want to feel like myself again...for my body to feel the way that I know it can.”

However, despite how difficult it’s been, the singer made a pledge to fans to stop over-analyzing her every flaw and appreciate what she is able to do in the wake of her recent pregnancy.

“As I was working out today, I realized that for the past 11(ish) months, my body has not belonged to me. It was a perfect home for Jacob. And even now it belongs to him every time he drinks his milk,” she said. “As I prepare for red carpets and for life on tour, right now I make a promise to myself to start appreciating what my body CAN do and stop focusing on what it can’t. I promise to stop analyzing every angle and every curve and every pound and every meal. I’m going to keep staying the path because it is a journey and as long as I’m always working towards my goals, one day I’ll reach them.”

She concluded: “I’m going to take it day by day, smile at the girl in the mirror, and work out because I love this body and all it has done and will continue to do!”

This isn’t the first time the star has used her social media platform to be open about the struggles of motherhood. She previously tweeted about her pregnancy insomnia, jokingly wishing that it affected her husband as well.

"Dear pregnancy insomnia," the country superstar tweeted. "Please go bother someone else…like dads. Go bother dads. My husband sleeps so soundly and peacefully and I’ve been awake for 2 hours (so far). How is this fair? Imma lose my mind!"
