How to train your chest

The engine of every press

Anatomy

The pectoralis major is a large, fan-shaped muscle that covers the front of the chest, with an upper (clavicular) head and a lower (sternal) head. Its primary function is horizontal adduction, bringing the arms across the body, and internal rotation. It also assists in shoulder flexion. The pectoralis minor lies beneath it and tilts the scapula forward. In daily life the chest muscle is active in pushing and hugging motions; in training it drives every press and fly variation.

How to train it

Pressing angles determine emphasis: incline work biases the upper (clavicular) fibers, flat and decline work hits the lower sternal fibers more. Both compound presses (barbell, dumbbell) and isolation moves (flyes, cable crossovers) are useful: presses overload in the stretched position, flies overload at the shortened position. Eight to fifteen reps for hypertrophy; aim for two to four sets per angle, two to three sessions per week. The most common mistake: flaring the elbows 90 degrees from the torso, which stresses the shoulder joint and reduces pec activation. Tuck the elbows to about 45–75 degrees.
