Exercise for Bigger Butts

Having a curvy posterior can give your body a shapely appearance when wearing your favorite pair of jeans. Infomercials flood the late-night television airways with padded undergarments that add curves with no work involved, but the results are limited. You can develop the muscles in your glutes to add size and shape to your butt. The key to gaining muscle mass is lifting with heavy weights to challenge your muscles. Train your lower body twice per week to see sizeable gains in as little as four weeks.
Dumbbell Lunges
Performing lunges develops the muscles in your glutes, quadriceps, hamstrings and calves. Begin in a split stance with your right leg in front and dumbbells in each hand. Slowly lower you left knee towards the ground until your right knee is bent at a 90-degree angle. Keep your back straight the entire time. Keep your weight focused in your front heel and press up, returning to the starting position. Repeat for four sets of 12 repetitions. Use moderately heavy dumbbells, so that you notice difficulty after completing eight repetitions.
Barbell Squats
Squats build your quadriceps, glutes, hamstrings and calves. Stand with your feet shoulder-width apart, holding a barbell behind your neck on your trapezius muscle. Keep your chest elevated and sit your hips back until your thighs are parallel to the floor and your knees are bent at 90 degrees. Squeeze your glutes and press back up until your legs are straight, returning to the starting position. Repeat for four sets of 12 repetitions. Perform squats with a heavy barbell. Ten repetitions should be a challenge to complete.
Step-ups
Step-ups target the muscles in your glutes to lift the area and build shape. Stand in front of a flat bench or aerobic step with your hands at your sides. Place your right foot on the center of the bench. Step up onto the bench using your right leg and tap your left foot on the bench for balance. Step down with your left leg while your right foot remains on the step. Repeat the movement for four sets of 12 repetitions on each leg. Increase the intensity of the exercise by holding dumbbells in each hand.
