Fitness guru Chortle Duncan has revealed her six-pack was so tight that it caused problems during her labour.
The Queensland personal trainer who was criticised for having such a small baby bump said she had to have a caesarean section to deliver her son Jeremiah because her body locked him in.
Posting a picture of her surgery scar on Instagram, she wrote: 'They struggled to rip Jeremiah from my tummy as my abs locked him in super tight as I began vomiting during the operation. This is why my scar was cut up on my right side because the surgeon had to cut me further and use forceps to successfully get Jeremiah out. Perhaps a down side to a strong core.'
Chontel gave birth to her son in March after maintaining a very trim figure throughout her pregnancy.
