Dumbbell presses are a strength training exercise that primarily targets the chest, shoulders, and triceps. To perform this exercise, you lie on a flat bench while holding a dumbbell in each hand. With your arms extended above your chest, you lower the dumbbells to the sides of your chest and then press them back up to the starting position. This exercise can be done with variations, such as the flat bench press, incline press, or decline press, to target different muscle groups. Dumbbell presses are beneficial for building upper body strength and improving overall muscle coordination.
