Katherine revealed that she shed the weight she had gained by following Kayla Itsines workout program via the SWEAT app. "
I was wholly and totally inspired by Miss @rachparcell and the before and after pics she shared after taking the #bbg challenge. 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 wrote.
"I found a fantastic app called #sweat that features several different #bbg programs you can choose from and makes it incredibly easy to do anywhere, which for me means in my bedroom at home! I won’t lie, the workouts are real ass kickers but the progress I’ve made in only 5 short weeks has kept me motivated and inspired to keep going!"
Heigl's story comes just a few days after Blake Lively shared photos of her 14-month weight loss as well.
Here's to the slow and steady approach, you go girls!
