Jill Duggar may be seven months pregnant but that doesn't stop her from hitting the gym to stay fit. The “19 Kids and Counting” star shared a selfie on Friday, flashing a big smile as she headed for her workout.

In the picture, posted on her Instagram account, the 23-year-old mother-to-be went without makeup and revealed a song from her playlist that she chose to listen on her way to the gym. Jill told her fans that she was listening to a religious sermon.

"Walking at the gym this morning while listening to a sermon by Pastor Rick Warren on the #OnePlace app!" the conservative Christian captioned the photo.

Jill’s choice fetched her praises from her fans on social media.

"This country needs more families like the Duggars," one of her fans wrote. "I hope they have hundreds of kids to repopulate the USA with common sense people who have high morals." Another fan wrote: “You are such an inspiration too me in a lot of ways.”

Jill, who recently celebrated 200 days of marriage with Derick Dillard, is pregnant with the couple's first child, a boy, who is due in March.

"It's been 200 days since my best friend and I @derickdillard said "I do"! I'm blessed beyond measure!" Jill wrote, as she posted a photo of her wedding day on her Instagram account.

On Monday, Michelle Duggar and Jim Bob Duggar wrote on the Duggar family’s official Facebook page about Jill's pregnancy.

“Sweet picture of our Jill and her little one,” Michelle and Jim Bob wrote, and posted a photo showing Jill cradling her bump while holding a sign that says she is 28 weeks and four days pregnant.

“At this point in gestation, there is now a 90 percent chance that he could survive outside the womb,” the caption of the photo read. “Life is beautiful! We can’t wait to meet this boy!"

“19 Kids and Counting” will return to TLC for Season 9 in February. The upcoming season will feature Jill's pregnancy and videos of her newlywed life, according to the Duggar family blog. Jessa Duggar’s wedding to Ben Seewald, which took place in November, is also scheduled to feature in the new season.
