There she goes again: Kim Kardashian ditched her clothes to pose for the cover of November's W magazine.

To keep her body in peak condition, the E! star works out with trainer Gunnar Peterson (who has also trained Jennifer Lopez). "She is always on time, or early, and always comes in with a great attitude," Peterson told "I mean, this is someone who is clearly enjoying the ride, and I like to see that. There’s no bitterness; there’s no drama."

To get your own Kardashian-worthy booty, incorporate the following moves (courtesy of celeb trainer Ramona Braganza) into your workout.

1. Weighted Squats  Hold a 5 to 10-pound dumbbell in each hand. Sit down in chair position while keeping weight back in the heels, and stand back up by squeezing your glute muscles and pushing through the heels. This focuses on the back of the legs rather than the quads. Repeat 10 to 12 reps.

2. Single-Leg Lunges  Start with one foot behind you on a workout bench and one on the floor. Slowly lunge down. Complete 10 to 12 reps with each leg. To add intensity, hold weights in each hand (Start with 5 pounds add work your way up to heavier weight). "It's better to do fewer reps with more weight or else you won't achieve results," Braganza warns.

3. Step-ups  Start with left foot up on a workout bench in front of you, and the right foot on the floor. Step your right foot up on the bench, then lower. Repeat 12 reps with each leg.
