Khloé Kardashian is demonstrating exactly how she works out her most famous asset.
The secret to a defined derriere? According to Kardashian, 31, it’s squats.
In her latest Khlo-Fit video, “The One Exercise You Need to Boost Your Booty,” the reality star holds a squatting position on a Bosu ball. The ball creates instability and makes the move more challenging.
“Your core is going to fire and your legs are going to recruit different muscle firing patterns to stabilize your position, which makes the muscles more efficient,” Kardashian’s trainer Gunnar Peterson explains.
If you don’t have a Bosu ball, Peterson says you can use stacked towels, a pillow or an air mattress to stand on while squatting.
“I can do it on anything that’s going to give me instability, and it will challenge me that way,” he says.
Peterson also demonstrates how to do the Kocktails with Khloé host’s slide-board ab workout at home. Cookie sheets on a carpet achieve the same gliding effect, so to do Kardashian’s move, place your hands on the sheets while down on all fours, and slide your upper body in and out.
“The key is on the way back, not to drop the hips and butt back so you disengage,” says Peterson.
Kardashian says her workouts help keep her on track – both mentally and physically.
“I definitely think the physical and the mental go hand in hand,” the newly single star told PEOPLE last month. “I feel so good in the gym that it [affects] the rest of my day. It’s a healthy addiction. It’s like buying your sanity!”
