Incline Dumbbell Bench Press
The incline dumbbell bench press combines an inclined bench with independent dumbbells, loading the upper chest through a deeper range than a barbell allows. Set at roughly 30 degrees, it emphasises the clavicular head of the pectoralis major while letting each arm follow its own natural pressing path.
Also known as: Incline dumbbell press, Incline DB press, Upper chest dumbbell press

What muscles does the incline dumbbell bench press work?
Primary movers
- Pectoralis major (clavicular head)
- Anterior deltoid
Assisting muscles
- Pectoralis major (sternal head)
- Triceps
- Rotator cuff
- Serratus anterior
This exercise stacks two advantages. The incline angle puts the upper arm on the upward-and-across path that the clavicular head of the pec produces, and the dumbbells allow that path to be travelled further than a fixed bar permits.
The stretch at the bottom is the more significant of the two. A barbell stops at chest level, several inches short of where the arms could actually descend. Dumbbells let the upper chest reach a genuinely lengthened position, and loading a muscle at long lengths is one of the more consistently supported drivers of hypertrophy.
At the top, dumbbells allow the hands to travel towards each other. The pec's job is to draw the arm across the body, and only unfixed hands let it finish that action, a barbell locks the hands at a set width and stops the movement early.
The anterior deltoid contributes throughout, as it does in any incline press. Around 30 degrees the chest still leads; as the bench gets steeper the deltoid takes over, and by 45 degrees you have moved a long way towards a shoulder press.
The stabiliser cost is real. Balancing two loads on an incline is harder than on a flat bench because the shoulders are in a less advantageous position, so expect noticeably lower weights than either flat dumbbell pressing or incline barbell pressing.
How to do the incline dumbbell bench press
Setup
- 1
Set the bench to roughly 30 degrees.
- 2
Sit with a dumbbell resting on each thigh, palms facing inward.
- 3
Lie back while kicking your knees up one at a time to drive the dumbbells to shoulder height.
- 4
Pull your shoulder blades together and down into the bench.
- 5
Press the dumbbells to arm's length above your upper chest with palms facing forward.
Execution
- 1
Lower the dumbbells to the sides of your upper chest, elbows at roughly 45 degrees from your torso.
- 2
Descend until your upper arms are at or just below the level of your shoulders.
- 3
Keep your wrists stacked over your elbows throughout.
- 4
Press up and slightly inward so the dumbbells finish close together above your upper chest.
- 5
Stop just short of a hard lockout to keep tension on the chest.
- 6
Control the descent over two to three seconds and keep your shoulder blades pinned.
Common incline dumbbell bench press mistakes
Setting the bench too steep
Using 45 degrees or more in the belief that it hits the upper chest harder. Past about 30 degrees the anterior deltoid progressively takes over, and the exercise drifts towards a shoulder press.
The fix: Stick to around 30 degrees. If the movement feels like it is burning your front delts more than your chest, the bench is too upright.
Letting the dumbbells drift towards your head
Pressing the weights up over your face rather than your upper chest. It puts the shoulder into deep flexion under load and takes the chest out of a strong position.
The fix: Keep the dumbbells tracking over your upper chest and shoulders. If you can see them directly above your eyes, they have drifted too far back.
Bouncing out of the bottom
Dropping quickly and using elastic recoil to reverse the rep. It skips the stretched position, which is the most productive part of the movement and the reason to use dumbbells here at all.
The fix: Take two to three seconds to lower and pause briefly at the bottom before pressing. Reduce the weight so this is possible.
Losing shoulder blade position
Letting the shoulders roll forward as fatigue accumulates. The chest loses its stable base and the shoulder joint takes load it should not be carrying.
The fix: Set the shoulder blades back and down before the first rep and consciously hold that position, particularly on the final reps of a set.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Hypertrophy | 3–4 | 8–12 | Moderate, 1–2 RIR | 90–120 s |
| Strength | 4 | 6–8 | Heavy, 2–3 RIR | 2–3 min |
| Stretch-emphasis work | 3 | 10–15 | Light to moderate, slow eccentric | 90 s |
This is one of the best single exercises for upper chest development, and it is a reasonable choice as the main pressing movement on a chest day rather than only an accessory. Expect lower loads than both flat dumbbell pressing and incline barbell pressing, the angle and the stability demand compound. Because the front delts take a meaningful share of the work, keep an eye on your total weekly pressing volume if you are also training overhead.

Low-Incline Dumbbell Press
EasierA 15–20 degree bench keeps more load on the chest and less on the front delts. A good option if 30 degrees irritates your shoulders.
Neutral-Grip Incline Press
EasierPalms facing each other reduces shoulder external rotation, which most people with irritable shoulders find considerably more comfortable.
Single-Arm Incline Dumbbell Press
HarderPressing one arm at a time adds a substantial anti-rotation demand on the core and fully exposes side-to-side differences.
Incline Barbell Bench Press
AlternativeAllows heavier absolute loading and is easier to progress in small increments, at the cost of range of motion.
Dumbbell Bench Press
AlternativeThe flat version emphasises the larger sternal head. Running both angles develops the chest more evenly than either alone.
Frequently asked questions
What angle should the bench be for incline dumbbell press?
Roughly 30 degrees. This is enough to bias the clavicular head of the pec while keeping the chest as the primary mover. At 45 degrees and beyond the anterior deltoid takes an increasing share of the work, so a steeper setting generally means less upper chest stimulus rather than more.
Is incline dumbbell press better than incline barbell press?
For upper chest growth, usually yes, the deeper stretch at the bottom and the ability to bring the hands together at the top are both real advantages, and neither arm can compensate for the other. The barbell version allows heavier loading and finer progression, so it is the better choice if strength is the priority.
How low should I lower the dumbbells on an incline press?
Until your upper arms are at or just below shoulder level. The extra depth compared with a barbell is the main reason to use dumbbells here, but only if you can control the weight out of that position. Stop higher if the bottom feels unstable or pinchy in the shoulder.
Why can I lift so much less on incline dumbbell press?
Two factors stack. The incline angle reduces the leverage of the large sternal head of the chest, and independent dumbbells demand far more stabilisation than a bar. It is normal for this lift to be well below both your flat dumbbell press and your incline barbell press.
Do I need both flat and incline dumbbell press?
Not strictly, but the chest develops more evenly with both. The sternal and clavicular regions of the pectoralis major have different fibre orientations and respond to different pressing angles. If you only have room for one, flat pressing trains more total muscle, but including an incline movement is the standard way to fill the gap.
