Decline Dumbbell Chest Press

The bench press is one of the most popular exercises in strength training. It is a compound exercise that engages several large muscle groups. The chest muscles and the front of the shoulder muscles are used to pull the upper arm forward and inward. The triceps are used to extend the arms. Muscles in the shoulders, back, and lower back work along to stabilize your body.

The bench press can be performed in different ways to emphasize the various muscles involved. The bench can be flat or angled. In an incline position, with the head higher, while decline refers to a position where the head is directed toward the legs. In this decline variation, more emphasis is placed on the lower fibers of the chest muscles.

The bench press generally refers to the classic barbell variation. In this variation, the resistance is provided by dumbbells.

Decline dumbbell bench press execution

Lower the dumbbells in a controlled manner. Depending on your shoulder mobility, lower your elbows until they are beside your torso, or lower them slightly farther.

Press explosively by driving your shoulders and upper arms upward and extending your arms almost fully. Make sure your forearms and hands remain aligned throughout the movement. The back of your hand should continue straight into your forearm.

Decline dumbbell bench press

Agonist muscles:

Pectoralis major
Pectoralis minor (depending on execution)
Anterior deltoid (front fibers of the shoulder muscle)
Triceps brachii
Serratus anterior
Coracobrachialis

Stabilizing muscles:

Rotator cuff (stabilizing shoulder muscles: supraspinatus, subscapularis, teres major, teres minor)
Serratus
Trapezius
Biceps brachii
Latissimus dorsi
Core muscles

Decline dumbbell bench press setup

Choose dumbbells of the appropriate weight for the desired number of repetitions.
Check the angle of the bench.
Sit at the end of the decline bench with the dumbbells upright on your knees.
Make sure the tops of your feet are in contact with the foot pad.
Lie back.
Keep your hands in a pronated position, with your thumbs pointing toward your face. Keep your elbows close to your sides.
Press both arms straight up so they point upward at shoulder width, while maintaining a slight bend in the arms. Rotate your thumbs inward. This is your starting position.

Decline dumbbell bench press technique

A partner who hands you the weights before the exercise and takes them from you afterward can be very helpful with the downward-sloping bench.

The decline position may take some getting used to. This is especially true when you almost extend your arms and raise them in the same line as on a flat bench. Because of the angled position, gravity pulls the dumbbells not only downward but also backward. Your almost-extended arms should be perpendicular to the floor, not perpendicular to your torso. Therefore, direct them more toward your abdomen than toward your chest.

Why decline?

Many studies have examined the effect of different bench positions.

Because they are conducted under different conditions, they sometimes show different results. Nevertheless, we can identify a common thread in these studies and point out possible exceptions.

Flat vs. incline & decline

An incline bench increases activation of the chest-muscle fibers that run from the clavicle to the upper arm. The involvement of the chest-muscle fibers that run from the sternum to the arm is lower. This primarily trains the upper part of the chest. In terms of surface area, this is approximately one-third of the chest muscle.

A decline bench instead increases the involvement of the lower chest-muscle fibers, while the upper part has to work less. These lower fibers make up approximately two-thirds of the chest's surface area.

Although this is supported by multiple studies, some studies show different effects.

Dumbbells vs. barbells:

The dumbbell bench press has advantages and disadvantages compared with the barbell, depending on the goal. For example, the shoulder muscles may have to work harder to stabilize the weight. Unlike with a barbell, you now have to prevent the weight from tilting not only forward or backward. With dumbbells, you must also prevent inward and outward tilting.

According to some studies, dumbbells require greater involvement of the pectoralis major and biceps and less involvement of the triceps compared with the barbell bench press.

Working with dumbbells can also make it easier to go to your limit without a training partner. After all, there is no bar to worry about. However, dropping the dumbbells on the floor beside you at the end of the exercise does nobody any favors, including you. You may have performed the exercise perfectly and then sustain a shoulder injury while putting the weights down.

Tip: After the last repetition, rotate your hands back to a neutral position, with your thumbs pointing toward your face. At the same time, bring your knees toward your dumbbells. Now rock yourself upright so that you return to the starting position, seated with the dumbbells on your knees. The dumbbells assist the movement by pushing your legs downward and thereby tilting your upper body upward. In the same movement, you can immediately stand up to put the dumbbells away. This reduces the load on your arms, shoulders, and chest when you are already fatigued and prevents shoulder injuries and broken toes for other gym visitors.
