The former High School Musical star was snapped flaunting her taut tum as she made her way round Runyon Canyon Park in California yesterday (2 January), armed with a water flask and her mobile phone (of course!)
There's no denying the brunette beauty has an incredible figure, and she's clearly keen to maintain her toned silhouette for the New Year.
Vanessa was completely kitted out for her expedition, wearing a pair of black capri pants by Nike SoulCycle paired with a striped sports bra.
She tied her Nike jacket around her waist and added a visor by Adidas to shield her peepers from the blaring sun.
In true Vanessa style she couldn't be without her jewellery, accessorising her sporty ensemble with a couple of delicate necklaces and bracelets.
But her health streak may have ended there, as post-workout the starlet was spotted clutching a menu for Spitz, an eatery specialising in döner kebabs.
She also appeared to have magically acquired a quilted Chanel handbag... we wonder where that was hiding during her hike?
