Kim Kardashian’s Wedding Workout

Kim Kardashian is famous for her gorgeous looks and killer curves, including her equally-as-famous, frequently photographed sculpted derriere. While she can clearly thank mom and dad for those good genes, the reality starlet is working hard to keep her fabulous, bodacious body in check for her upcoming wedding to NBA player Kris Humphries this weekend.

Who can blame her? Tying the knot in front of a camera crew with all of America watching (as part of a four-hour wedding special airing on E! in October), along with a bevy of A-listers attending is enough to make even the most confident bride-to-be want to log some serious gym time. With the help of her powerhouse trainer Gunnar Peterson, who's been working with Kardashian to keep her figure fab for the last three years, there's no question the stunning star will be looking va-va-voom amazing in her Vera Wang gown come August 20.

"I think the goal is to look her best like any bride -- and groom for that matter! -- and to be able to withstand the stress of a wedding," Peterson says. "In her case a wedding that will be on the world's stage!" Peterson, who boasts a high-profile celebrity client roster including Sofia Vergara, Jennifer Lopez, and Angelina Jolie, was inspired to become a personal trainer after being overweight as a kid. So just how did the devoted, hard-working celebrity trainer get Kim K's bridal bod in tip-top wedding shape? "Kim's training is based on 'if you stay ready you never have to get ready,'" Peterson says. "She grinds in the gym year round and makes the right choices outside of the gym so the payoff is increased."

Kim Kardashian's Favorite Calorie-Blasting Workout

Peterson has been working with Kardashian three to five days per week, depending on the busy star's schedule. While her workouts were essentially the same as previous routines, they were a "little quicker paced." With all the buzz surrounding Kardashian's upcoming nuptials, it's no wonder why future brides from all over the world are finding inspiration for their big day in Peterson's workouts. "Don't starve yourself. Try to get your rest so that your body can recover from your workouts, and so that your immune system is firing on all cylinders," advises Peterson. "You don't need to be rundown while you walk down the aisle!"

Hollywood's Hottest Bridal Bodies

The good news is that you don't have to be a blushing bride-to-be to benefit your body with Kim Kardashian's wedding workout. Here, Peterson gives us the scoop on her fitness routine.

What You'll Need: dumbbells, a medicine ball, a weighted sled, a treadmill and a whole lotta' stamina!

How it Works: This workout combines five moves with high-intensity cardio intervals to work your glutes, shoulders, quads, obliques, abs, hips, core, and more.

STEP 1: Squat Press
How to do it:
-Begin with your back straight and feet shoulder-width apart. Squat down to a 90-degree angle while keeping your back erect. Keeping your abdominal muscles tight, look straight ahead and slightly up with your eyes.

-Hold the dumbbells in front of you comfortably at about the height of your shoulders with a slight bicep and chest flex to keep them in place. Concentrate your weight on the back of your heels but don't lift up your toes during the movement.

-Rise out of the squat with a slight explosion while maintaining form and control. Breathe out on the exertion. Simultaneously press or push the dumbbells up and over your head. End the movement by bringing the dumbbells back into the shoulder position. That's one rep. Do 12 to 20 reps.

Which Muscles the Move Works: glutes and shoulders.

STEP 2: Rear Lunge with Front Kick
How to do it:
-Stand straight with feet shoulder-width apart. Place your hands on your hips or hold dumbbells in your hands at your sides (both will help with balance; dumbbells add resistance).

-Keeping your abs tight, step back with your right foot and lower into a reverse lunge. Squeeze your glutes as you push down through your left heel and kick your right leg in front of you as you straighten your left leg. That's one rep. Do 12 to 20 continuous reps, then repeat on the other side, kicking your left leg.

Which Muscles the Move Works: Glutes, quads and core.

STEP 3: Medball Rotations
How to do it:
-Stand with your feet pointed straight ahead and shoulder-width apart. Keeping your knees slightly bent, hold a medicine ball in both hands in front of your chest and extend your arms.

-Draw-in your navel, contract your glutes and tuck-in your chin. Rotate your arms and torso to one side, pivoting on your back foot in a repeated controlled motion. Use your abdominal and waist muscles to slow down and change direction to the other side. That's one rep. Do 20 to 50 reps.

Which Muscles the Move Works: Abs and obliques.

STEP 4: Sled Push
How to do it:
-Stand directly behind a weighted sled with both of your hands on the handlebars. Push forward on the sled with your back straight and your knees driving up and down to generate speed.

-Push the weighted sled in a consistent marching motion for 80 feet. For high-intensity cardio intervals, do this three to six times in between the other moves.

Which Muscles the Move Works: Glutes and core.

STEP 5: Lateral Slide on Treadmill
How to do it:
-Standing sideways on a treadmill at an incline, keep your feet just over shoulder-width apart. Bend your knees slightly and keep your back straight. Begin the exercise by shuffling to the left for 30 to 60 seconds, then turn around and repeat on your right side.

Which Muscles the Move Works: Hips, quads and core.

STEP 6: Push-ups to Mountain Climbers
How to do it:
-After completing five push-ups, stay in the push-up position and rest on the balls of your feet while bringing your left leg forward to your chest and back to its original position.

-Repeat this motion rapidly, alternating one leg forward and one leg back. This movement mimics the "climbing of a mountain." Complete 20 mountain climbers, then repeat the "push-ups to mountain climbers" three to five more times without getting out of the push-up position.

Which Muscles the Move Works: Everything! You'll be feeling it in the morning!
