After giving birth to baby North a mere seven months ago, Kim Kardashian could be forgiven (and also admired) for holding onto a few extra pounds.
Yet Kanye West's missus seems intent on achieving the perfect figure - and happily poses for Instagram pics on a regular basis to show the rest of the world how successful her exercise regime has been.
In the latest round of viral photos, Kim show off a trim bum, an ample chest and an enviable flat tummy.
Joined by her blonde friend Blac Chyna - whose posterior even eclipses Kim's famous behind - the pair are clad in workout gear, as if fresh from the gym.
Low cut tops and bare torsos are the order of the day as the pals pose in front of a large mirror, one cutting out their heads to allow for more intense focus on their toned bodies.
The Keeping Up with the Kardashians star captioned one of the snaps, 'Getting right for the new year', indicating that her fitness plan for 2014 will be just as rigid as last years.
In October, Kim posted an Instagram selfie wearing a revealing high-cut swimsuit entitled 'No filter'.
The photo went down well with fiancé Kanye at the time; the rapper re-posted the snap on his Twitter page, tweeting: "HEADING HOME NOW"
