The reality superstar, 23, appeared in a sideways mirror shot, that cut off at her head and thighs.

Her ample derrière was featured in all of its curvy glory, sheathed in a high-waisted pair of tight heather gray workout shorts from Alo. 

A patch of sweat was seen on the front of her hip. 

Kylie wore a matching sports bra top, with her bust partially covered by her upper arm.

Her endlessly long black wavy hair hung all the way down her back.
