The days of fancy fitness classes may officially be behind us. Millions of women around the world, celebrities included, have turned to Kayla Itsines’ Bikini Body Guide, or BBG for short, to completely transform their bodies in their own living rooms, and countless success stories make the program sound like a no-brainer. The latest to hop on the Aussie-led bandwagon: none other than Katherine Heigl, and her results are stellar enough to get you to give it a try, too.

It’s been almost 14 months since Joshua Jr was born and it has taken me about that long to really get back in shape. The first pic was taken one month after he was born. The second pic was taken almost a full year later and the last pic was taken this weekend. I wish I had a few from in between the first and second so you could really see how slow my progress was but alas...I was busy covering it all up those months, not posing in my unders! Anyway, 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 finally loose the last of my baby weight and do a deep dive search for the ab muscles I knew were buried under that belly somewhere! 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. 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! I am so grateful I’ve had a full year to find those ab muscles and get my butt back up where it belongs and wasn’t forced by work to snap back into shape but it is time to make the strength, fitness and overall health of my body a priority and I am so grateful that @rachparcell shared her story and got this mama motivated!

“It’s been almost 14 months since Joshua Jr was born and it has taken me about that long to really get back in shape,” the actress captioned the Instagram post of her jaw-dropping transformation shots, which the BBG program highly recommends each user take as a way to track progress and motivate you—and the rest of the BBG community—to keep powering on. While Heigl’s shots weren’t weeks apart—in fact, she explains the first picture was taken one month after she delivered, the second was taken almost one full year later and the last picture was taken this past weekend—they are no less impressive.

She continues, “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 finally loose the last of my baby weight and do a deep dive search for the ab muscles I knew were buried under that belly somewhere!” However, her main motivation to get going on the program was actually a fashion blogger who has been very transparent with her own BBG journey. “I was wholly and totally inspired by Miss @rachparcell [Rachel Parcell of Pink Peonies] and the before and after pics she shared after taking the #bbg challenge." Heigl adds that she had never heard of the program before, but because of how "damn great" Parcell looked after having her baby a few months before Heigl, she had to check it out. You can see a glimpse of Parcell's transformation below, which Heigl later thanks her for sharing and further getting “this mama motivated.” 

I can't believe I'm posting this!!! I've been so nervous to share it and when I took the photo on the left I swore to myself no one would ever see it except for me. In sharing this I hope it can motivate and inspire some of you to change your life because for me, this fitness journey has been completely life changing. In May I started the @kayla_itsines 12 week challenge thanks to some girlfriends who decided to do it with me. I quickly realized this program Kayla created was so much more than just working out to look good in a swimsuit. It was about pushing myself, loving myself, and seeing my body change and become stronger from my hard work and dedication. Head over to my blog post today to read all about my fitness journey!! I asked you guys to send in your questions so I answered all of those too! Let me know if you have any other questions! ❤️ #bbg #bbgtransformation #bbgmoms

Heigl opted to use the Sweat app, the official app for the Bikini Body Guide, which she says features several different programs and makes it incredibly easy for you to do anywhere, which for her, was her bedroom. But, she also offers a warning: If you’re looking for easy-breezy workouts, look elsewhere. “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!” 

Later, Heigl adds that it is time to make the strength, fitness and overall health of her body a priority—and by the looks of the comments on her post, such as, "You just gave me the motivation to finally get back into shape after my full hysterectomy”—she’s inspiring thousands of women to do the same.
