Booty Boot Camp : Ready to take a crack at it?

If you feel your "rear view" needs a makeover, the right fitness routine can provide a natural lift. Can you achieve the "perfect" Brazilian beach butt seen on TV? That depends partly on your body type and genetics, but most everyone can shape up to look better in jeans.

Firm Up Without Bulking Up
Some people's muscles rise to a challenge by bulking up. If that's your genetic destiny — and you don't like a pumped up look — focus on aerobic activity over weight training.

Don't crank the resistance up too high on an exercise machine. And skip the weights when you do butt-sculpting exercises.

Variation: Side Lunge for MEN's

The side lunge directly targets the muscle on the outside of the hips, the glutes, and tones the inner thighs, too.

Form: From a wide stance, bend one knee. Keep the shinbone under that knee vertical to the floor. If the knee falls inside the foot, use a shorter stance. Lean forward slightly, but keep your shoulders behind your knees to avoid injury. Choose a hand position that helps with balance.

Tone Your Tush With Cardio
In the gym, stair steppers, arc trainers, and elliptical machines are good choices to challenge the glutes while giving your heart and lungs a healthy workout. Inline skating and cycling are other heart-pumping options that tone the tush.

Walk the Hills
Walking is a natural, anywhere, no-fuss butt workout. Tackle the hills for maximum gluteal impact — and to burn a few more calories when you're trying to lose excess body fat. On a treadmill, use a 5% to 7% incline to increase the workout.
