While she always looks good no matter what, the 27-year-old has wasted no time to get back into a fitness routine.
In the video, Lara performs a series of exercises and proclaims: “Oh s**t!”
A personal trainer then asks her to do “five more” leg raises and the super mum, who welcomed Rocket with husband Sam Worthington ten weeks ago, completes the exercise with the ease.
The mum-of-one gave birth to her newborn at Los Angeles Cedars-Sinai hospital with her Sam and mum Sharon Bingle by her side in March.
And just last week Lara treated us to belated baby bump shot via Instagram. In the image, the Cronulla-born beauty looks stunning in a plunging lace dress with black panels.
She captioned the shot: “28 weeks pregnant in London.”
Meanwhile the blonde beauty has only shared a photo of her little man’s feet on social media alongside the caption: “March 24th 2015 best day of our lives.”
In her latest post, Lara shows off he petite frame in an all-black work-out ensemble.
We worked up a sweat just watching the clip, so we can only imagine how Lara felt!
