Booty Boot Camp

If you feel your "rear view" needs a makeover, the right fitness routine can help give you a lift. Can you achieve the "perfect" Brazilian beach butt seen on TV? That depends partly on your body type and genes. But most everyone can shape up to look better in jeans. These pictures show you the moves.

Behind It All: Meet Your Glutes

The shape of the buttocks is defined by muscles known as the glutes. That's the gluteus maximus, gluteus medius, and gluteus minimus, as well as the fat that lies over them. Walking, running, and climbing all work the glutes. Strength training that targets these muscles can help give you a tighter, more rounded look. Adding a few butt-busting moves to your routine may be enough to see a change.

Squat and Tone

The squat tops every list of butt-sculpting exercises. It directly works the glutes.You can build bigger bottom muscles by adding hand-held weights.Slowly lower the hips as if sitting in a chair; then return to standing. Make sure your knees do not push out in front of your toes. Keep your torso tight and back straight.

Or Try a Ball Squat

If you're just starting out, a large ball can help with balance while you master the form. For each exercise on our list, aim for three sets of 15 reps. Try to do each exercise three times a week with cardio or exercises focused on other body parts on other days.

Forward Lunge

With your feet parallel and hip-distance apart, take one giant step forward. Lower your body slowly, bending both knees, and return to standing. Repeat on the other side. Bend your knees no more than 90 degrees. Keep your front knee stacked right over your front ankle. Do not rest your back knee on the ground.

Or Try a Backward Lunge

When you step backward into a lunge, it works the glutes a little harder. Your workout gets variety, too. Lunges also add flexibility to your hips. They align your body better, too, something that can suffer when people spend long hours sitting at a desk.
