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.
