Keeping up with Kim! Now Kylie Jenner, 18, jumps on the waist training trend loved by her big sisters

Kim Kardashian may have single-handedly ignited the waist training trend, with her sisters Khloe and Kourtney quickly getting in on the action.

And now even the youngest of the siblings - 18-year-old Kylie Jenner - has revealed she is a fan, promoting a waist trainer on her Instagram on Saturday.

Kylie shared a selfie from her $2.7million Calabasas mansion, revealing that she had just been for a stroll in the corseted device.

'Just took my dogs on a walk wearing only da best @premadonna87 @waistgangsociety,' she wrote alongside the snap.

'Nothing wrong with a little extra help. They also got some new stuff in I wanna try.'

Kylie wore the waist trainer over a black tank top and black and white printed leggings. She styled her dark locks in a top knot and sported just a little make-up.
