Kim Kardashian's curves don't come easy.
"Unless you're genetically gifted, booties definitely take a lot of work to develop," says celeb trainer Ramona Braganza (clients include Jessica Alba and Ashlee Simpson) of the reality star's rear end, which was just voted "Best Booty" in UsMagazine.com and Gold's Gym's first-ever Hollywood's Hottest Bodies Awards.
To look like Kardashian, 29, Braganza recommends incorporating squats, lunges and step-ups into 4-day-a-week workouts "to really focus on the butt." Here are a few moves she suggests:
1. Weighted Squats: Hold a 5 to 10-pound dumbbell in each hand. Squat while keeping weight back in heels. Sit down in chair position, 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, and slowly lunge down. To add intensity, hold 5-pound weights and work your way up to heavier weights while doing 10 to 12 reps with each leg. "It's better to do fewer reps with more weight or else you won't achieve results," Braganza warns.
3. Step-ups: Start with one leg up on a workout bench in front of you, and one on the floor. Step up to both legs on the bench; repeat 12 reps with each leg.
