(Cover) - EN Star Style - Khlo Kardashian loves working out on her stairs.

The American reality television star has a curvaceous figure and chooses to keep it toned by walking up and down steps in her house instead of going to the gym.

Khlo believes that she gets a great workout from the cost-effective exercise, especially firming up her legs and increasing her heart rate.

I love working out on the stairs! Cardio and working my legs! Wooohooooo (sic), the celebrity wrote on her Twitter page. The brunette beauty who has featured in Keeping Up with the Kardashians with her sisters Kim and Kourtney, is very accepting of her fuller figure.

She has admitted having a bigger butt which benefits from the staircase cardio work-out, and has previously advised women with her frame not to wear bikinis with ties on the beach.

When you have a bigger butt, bottoms without ties on the side sometimes will cut into your skin. I have a booty, so I like ties because I can loosen them up a little, she previously said. (C) Cover Media
