It's an exercise you're familiar with, whether you know it or not. A supine dumbbell press is essentially a bench press performed with dumbbells instead of a barbell. Supine means you're lying on your back while you press the dumbbells up, working your pectoral muscles along with a few others, too. Supine dumbbell presses target your pecs, the biggest muscle on your chest.
Muscles Overhead Presses Work. The upper-body push muscles missed by the deadlift are all hit by the overhead press, as long as you use a form that consciously hits the pectorals. When performing the overhead press, you have the choice to bring the bar down behind your neck or to the front, over the clavicles. Behind-the-neck presses work the deltoids and triceps, but miss the pectorals. But overhead presses to the front are the single-best upper-pectoral exercises, and they even utilize the lower pectorals to some degree.
