The fitness model who gained fame for a photo comparing her six-pack baby bump to an acquaintance’s pregnant belly has stunned followers again with a photo of her body just five days after giving birth.

Chontel Duncan, who gave birth to a baby boy named Jeremiah Thomas Duncan on March 25, detailed her post-birth recovery for her Instagram followers.

“Little D now known as Jeremiah ‘MIAH’ came 39weeks 2days (as you all would have noticed). My body is tender, it feels like someone did 12 rounds in the boxing ring using my core as the target. So much swelling is yet to go down & so much healing is yet to happen.”

In the most recent update, she told her 434,000 followers that midwives and nurses told her she is on track for a quick recovery.

“It’s super crazy how different my body feels, I can’t believe my bump is gone & I no longer have my baby hiding inside of me. To a degree I miss it but reality of actually having Miah in my arms is so much better,” she wrote. “I wonder because I can’t get back into training for a longer period of time how my body will change through purely just recovery/rest and nutrition… I’m excited because it gives me more time with Miah lol I’m an obsessive new mummy!!!”

Despite concerns from commenters about about her svelte pregnancy body and the health of her unborn child, Duncan told followers in a post that her son weighed a healthy 7 pounds 13 ounces, with “absolutely nothing medically wrong.” She also said in an earlier post that she wanted to share the baby bump comparison photo to demonstrate that every woman carries a pregnancy differently.

The post-baby body post has gained more than 11,000 likes and nearly 700 comments.
