Upper fibers of the pectoralis major used in incline pressing, contributing to upper-chest shape and shoulder stability.

Central chest fibers responsible for strong horizontal pressing and overall chest thickness.

Lower portion of the chest assisting in decline pressing and contributing to lower-chest definition.

A large primary chest muscle responsible for pressing and bringing the arms toward the midline. Essential for upper-body pushing strength and shoulder stability.

A deep chest muscle that stabilizes and moves the scapula, supporting proper shoulder mechanics.

Muscles along the rib cage that stabilize the scapula during pushing and overhead movements. Important for preventing winged scapula.
