Most people train “chest” like it’s just one muscle… but your chest is made up of three main parts - upper, middle, and lower - and each plays a unique role in how you move.
✅ Upper Chest (Clavicular head): helps lift your arms upward & across your body.
✅ Middle Chest (sternal head): the powerhouse for pressing movements straight out in front of you.
✅ Lower Chest (abdominal head): assists with pushing movements on downward angle and controlling arm movement towards your hips.
When you target all three, you’re not just building strength - you’re creating a balanced chest that’s both strong AND functional.
Pro tip: Changing bench angles, grip width, and movement paths can shift the focus to each section and improve overall development.
