What Chest Training Does

The pectoralis major has an upper portion and a lower portion. Developing the upper chest creates fullness just below the clavicle that gives your upper body three-dimensional appearance. Developing the lower chest creates the underbust definition that improves how your torso looks in fitted clothing. Chest training also develops the anterior deltoid and serratus anterior and strengthens the muscles that prevent your shoulders from rounding forward.

Best Exercises

Incline dumbbell press is your primary chest exercise. Set a bench to 30 to 45 degrees, press dumbbells from chest height to fully extended overhead, lower with control. Three to four sets of 8 to 12 reps.

Flat barbell bench press allows the most total loading for chest development. Grip just outside shoulder width, lower to your lower chest, press up. Three sets of 6 to 10 reps with progressive loading.

Cable chest flyes maintain tension through the full range of motion — especially at the stretched position where most of the growth stimulus from fly movements occurs. Cables at shoulder height, bring handles together in a hugging motion. Three sets of 12 to 15 reps as a finishing exercise.

Push-ups are underrated. A Slim Thick woman doing full push-ups — chest to floor, body rigid — is moving significant load. If you cannot do 10 full push-ups, make it a goal.

Programming

Train chest once or twice per week paired with shoulders and triceps. One compound, one isolation, three to four working sets each. Progressive overload on the compound every one to two weeks. Posture improvement visible within four weeks. Visible chest development in six to eight weeks. Read the Slim Thick Shoulders guide alongside this.
