So this is your secret, Blake Lively!
We'd be lying to your faces if we said we weren't rather impressed with the actress' body these days after welcoming her first child with Ryan Reynolds.
And while the Gossip Girl alumna has been staying pretty tight-lipped about her fitness secrets, today Lively was finally ready to introduce the man behind her physique.
"This fit dude, @DonSaladino NOSE how to kick my butt (See what I did there)," she wrote on Instagram while grabbing her trainer's nose. "#WhyIsCelluliteSoMuchCuterOnBabies. You'll die over his training on Broadway. Officially a maniac. Which is of course why we get along."
The past several months have been pretty jam-packed for the 28-year-old. In addition to raising daughter James, Lively remains busy with her Preserve lifestyle site.
In fact, she's already added fashion designer to her list of accomplishments. "I may not be able to draw worth a lick, but I am proud of this dress I co-designed with Amour Vent for @Preserve_Us," the proud mom shared on Instagram. "You better send me pics if you buy it!"
Perhaps this is only the beginning for a busy mom who is never afraid to dream big and work hard.
"To be honest, I could really see myself opening a clothing label and might even do it one day," she told German mag Jolie (via Belfast Telegraph). "But right now there is just no time for it. I really couldn't take any more sleep deprivation!"
