Looking your best on and off the camera takes hard work and dedication.  Jessica Simpson is known for having a naturally beautiful looking chest which is a combination of good genes and great workouts.  Here is an example of one of her workouts that you can try to get the best looking chest you could possibly have.  Do each exercise 3 times and aim for about 15 repetitions for each:

1. Incline push-ups
Purpose:
To target the muscles of the upper chest (pectoralis major).
Execution:
•    Place your hands on a step or stair and lie face down on your stomach with your hands on either side of the shoulders and your fingers spread.
•    With your feet together, get up on your toes by pushing your upper body away from the step until your arms lock at the top (exhale).
•    Slowly lower yourself back down to the floor making sure to keep the entire body straight like a board (inhale), and then repeat without letting your upper-body touch the step in between.

2. Reverse Ball push-ups:
Purpose:
To create stability and strength in the shoulders (deltoid group), chest (pectoralis major/minor), and arms (biceps and triceps brachii)!
Execution:
•    Start by lying face-down on the ball.
•    Place your hands at “10 & 2″ on either side of the ball pointing down.
•    Squeeze the ball as tight as you can for stability and push the ball away from you (exhale) until the elbows lock.
•    Slowly return to the starting position (inhale) and repeat without letting your chest touch the ball between reps!!

3. Dumbbell Chest Press
Purpose:
To work the muscles of the chest (pectoralis major), shoulders (deltoid group), and triceps (triceps brachii).
Execution:
•    Lie down on your back with your feet flat on the floor
•    Grasp the dumbbells and hold them on either side of your shoulders.
•    Slowly push the weight away from you towards the ceiling (exhale) until your arms are fully locked to ensure a full range of motion.
•    Lower the weight back down towards the starting position (inhale) and then repeat towards the body in line with the nipples (Inhale).

4. Dumbbell Fly
Purpose:
To develop the mass of the inner and outer chest (pectoralis major/minor).
Execution:
•    Lie down on your back on the floor.
•    Press the dumbbells straight up in front of you then create and hold a slight bend in the elbow.
•    Lower the weight down as far as you can on a wide arc, palms facing one-another, and the shoulders down (Inhale).
•    Lift the weights back up in a bear-hug type of movement (Exhale) and then repeat.

5. Pull-overs
Purpose:
To develop the muscles of the rib cage (serratus anterior) and the chest (pectoralis major/minor). A strong well-defined rib cage is very important for the overall performance of the chest and also helps to enhance the appearance of the pectoral muscles!
Execution:
•    Start by lying down on your back on the ball with the ball positioned right between the shoulder blades with your feet slightly spread.
•    Once in position, pick up the dumbbell and hold it with both palms pressed against the plate and then raise it straight up on top of you keeping the arms straight.
•    Lower the weight slowly behind your head in a wide arc until you feel a good stretch in the chest area (inhale).
•    Raise the weight back to the starting position along the same wide arc (exhale) by tensing up the muscles of the chest and rib cage and then repeat.
