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.
The decline bench press involves inverting the weight bench, creating an angle that is between 20 and 40 degrees, according to the American Council on Exercise. You can use either a barbell or set of dumbbells to perform this exercise, with weights that are heavy enough to perform 10 to 12 repetitions.
