Khloe Kardashian is sweating hard in the gym to tone up her body.
The 31-year-old reality star took to her Instagram page to share a pic, wherein she is seen working out on a stair-climber machine in a gym, and wrote, "No elevators in the gym. Must. Climb. Stairs. (Or ladder) thanks @gunnarfitness," E!Online reports.
In the pic, the 'Keeping Up with the Kardashians' star showed off her butt in black tights-covered backside.
Responding to one of her fans' question about her favourite booty workout, the reality star said that the stairs are best exercise for your lower body and that it's a great cardio workout.
Notably, Khloe had lost at least 35 pounds this year, thanks to her strict workout regimen.
