Blake Lively is the latest celeb to admit that snapping back to your pre-pregnancy body doesn’t come easy. She’s doing it with lots of gym time, an entire diet program, and a New Year’s resolution to hold her accountable.

“New Years resolution started early — I WILL fit into my jeans again gall darnet,” she captioned a pic of her food haul on Monday night. “Thanks @getepicured for making it tasty.”

And while a celeb endorsement like that doesn’t usually come cheap, this one was free. “This is not an ad,” she continued. “This is me getting it up for healthy food. ?????.”

But a nutrition regimen is just the beginning of her post-baby body plan of action. She’s also hitting the gym hard — at least when she’s not hiding from her personal trainer, Don Saladino.
