Katherine Heigl's post-baby weight loss didn't happen overnight

Despite what her before-and-after photos might suggest, Katherine Heigl’s post-pregnancy weight loss didn’t happen in a matter of days.
 
The actress welcomed Joshua Bishop Kelley, Jr, her third child with singer Josh Kelley, in December 2016.
 
Now, Heigl has detailed the efforts she’s made over the past 14 months to gradually “get back in shape”.

Heigl - who is also mum to daughters Nancy and Adalaide, whom she and Kelley adopted - had several motivations for keeping fit and healthy post-baby, including her upcoming role on Suits. 
 
“I have a beach vacation coming up, a new job I start filming in April and my deep desire to feel fit, strong and sexy propelling me forward the last two months to … do a deep dive search for the ab muscles I knew were buried under that belly somewhere,” she wrote.

“I had never heard of it but she looked so damn great (she had her baby just a few months before me) that I had to check it out,” she writes.

Rather than hitting the gym, Heigl followed Itsines’ workouts from the comfort of her own bedroom using the Sweat app.
