To get a derriere a la Angelina Jolie, try -
Squats: Stand with legs apart little wider than hop and squat down. Remember your knees musn't go in front of your feet, and squeeze your muscles as you come up to get the most from your Workout.
Lunges: Keep your upper body straight, with your shoulders back and relaxed and chin up (pick a point to stare at in front of you so you don't keep looking down). Always engage your core.
Step forward with one leg, lowering your hips until both knees are bent at about a 90-degree angle. Make sure your front knee is directly above your ankle, not pushed out too far, and make sure your other knee doesn't touch the floor.
Keep the weight on your heels as you push back up to the starting position.
