If you’re not including the incline dumbbell bench press in your chest day split, then you’re potentially missing out on some huge gains. Dumbbell movements require more core stability, balance, and core activation as opposed to just using a barbell or chest machine. Incline dumbbell bench press is one of the best compound chest exercises, to build more muscle and strength in chest, shoulders, and triceps.

Muscles Worked, Variations, and Research-Backed Benefits

What Is the Incline Dumbbell Bench Press?

The incline dumbbell bench press is a foundational compound movement used to develop the upper chest, shoulders, and triceps. Performing this exercise on a bench set at a 15–30° incline targets the clavicular head of the pectoralis major more effectively than the flat or decline bench press, while reducing strain on the shoulder joint and rotator cuff.

"Incline pressing preferentially activates the upper pectoralis fibers and may reduce shoulder strain due to altered biomechanics."
— Glass & Armstrong, Journal of Strength and Conditioning Research

Muscles Worked

• Pectoralis Major (Upper Chest)

• Anterior Deltoid

• Triceps Brachii

• Serratus Anterior (stabilizer)

• Core Musculature (as a secondary stabilizer)

By engaging the shoulders and triceps as secondary movers, the incline dumbbell press serves as a multi-joint movement, promoting upper-body strength and coordination.

Grip and Range of Motion Considerations

The flexibility of dumbbells allows lifters to adjust wrist angle, grip width, and range of motion to optimize both safety and muscle recruitment:

• A neutral grip reduces shoulder stress and increases triceps activation.

• A wider arc of motion emphasizes chest stretch and time under tension.

• A narrower descent can target the inner chest and assist with lockout strength.

"Dumbbell variations elicit greater activation in stabilizer muscles and allow for increased range of motion when compared to fixed-path barbell presses."
— Saeterbakken & Fimland, Journal of Sports Science & Medicine

Incline Dumbbell Bench Press Variations

To target the upper body from various angles and intensify training stimulus, consider these incline variations:

• Incline Barbell Bench Press – Allows heavier loading for strength development

• Smith Machine Incline Press – Safer for beginners or rehab settings

• Incline Dumbbell Bench Press on Bosu Ball – Challenges balance and increases core recruitment

Benefits of the Incline Dumbbell Bench Press

While the flat barbell bench press is a cornerstone for building pressing strength, the incline dumbbell bench press offers unique advantages in muscular development, injury prevention, and overall stability.

1. Upper Chest Development

The incline press targets the clavicular head of the pectorals, which is often underdeveloped. Focusing on this region helps create a fuller, more defined upper chest—essential for aesthetics and structural balance.

"Activation of the clavicular pectoralis is maximized at an incline of 30 degrees compared to flat and decline bench press positions."
— Trebs et al., Journal of Strength and Conditioning Research

2. Improved Shoulder Health and Stability

Dumbbells allow for natural shoulder rotation, reducing the risk of impingement and rotator cuff irritation compared to fixed-grip barbell pressing.

"The use of dumbbells permits a more natural pressing path, decreasing shoulder joint stress and improving muscle activation patterns."
— Escamilla et al., Journal of Orthopaedic & Sports Physical Therapy

3. Enhanced Core Engagement

Because each arm operates independently, you must actively stabilize your torso and spine, engaging your core and obliques to maintain proper alignment throughout the movement.

"Unilateral or independent limb exercises like dumbbell pressing increase activation in core musculature due to anti-rotational demands."
— Behm et al., Sports Medicine

4. Greater Range of Motion and Muscle Fiber Recruitment

Dumbbells allow you to lower the weights deeper than a barbell, leading to a greater stretch under load, which has been linked to increased hypertrophy in chest muscles.

"Stretching a muscle under load enhances fiber recruitment and contributes to mechanical tension—one of the key drivers of hypertrophy."
— Schoenfeld, Sports Medicine

5. Better Posture and Upper Back Strength

By improving scapular control and upper chest strength, incline pressing may help counteract the rounded posture common from sedentary lifestyles and excessive pressing volume.

6. Improved Balance and Symmetry

Since dumbbells operate independently, they expose imbalances in strength or mobility between arms, encouraging better neuromuscular coordination and helping to correct asymmetries over time.

Summary of Benefits:

• Builds a well-developed upper chest

• Enhances core and shoulder stability

• Supports joint-friendly pressing mechanics

• Increases range of motion and muscle engagement

• Promotes balanced muscle development

• Reduces risk of rotator cuff strain

How To Incline Dumbbell Bench Press

1. Lie flat on an incline bench and set your dumbbells on your knees. Kick up one dumbbell at a time, keeping them close to your body as you lay back. Plant your feet firmly into the ground, lay back and push up. Make sure your feet are placed proximal in towards your body, while keeping them flat on the floor. This will provide a good base for more driving power when it comes to heavy loads and finishing your set.
2. Back position is equally as crucial as your feet placement. Squeeze your shoulder blades by pinching them together and driving them into the bench and slightly arch your back.
3. Make sure your palms are rotated completely under the dumbbells. As you descend, follow your bend your elbows at a parallel 90 degrees, then push back up bringing the dumbbells together, while still keeping a slight bend in your elbows, not locking out. drive your feet into the floor, tightening your glutes, and pushing under the bar with one fluid motion, and extending the elbows again not locking out.

Incline Dumbbell Bench Press Tips And Tricks

1. Always focus on executing proper form. Your body works in a specific plane of motion. Ensuring your grip, feet placement, and breathing is in line with your lifts, will produce better results.
2. Make sure you are descending the dumbbells down directly in a straight line.
3. Maintain control, with a 4 second descent, slight pause and press back up.
4. Don’t pay attention to the weight. Everyone is different and we all have our own journey to follow. Ramp up your load and volume slowly overtime.
5. Incline dumbbell bench press should be used in your training program, but not used on every chest day training split. Exercise variability is important to increase muscle mass, strength, and core strength. Utilize different dumbbell and barbell variations within your training program.
6. When you plan to max out, make sure you have a spotter, so you can obtain one rep, with full range of motion.
7. Focus on your breathing. On your descent, breath in, brace your shoudlers, and tighten your ups, then breath out on your ascent, pushing the weight back up.
8. If you want to work your triceps, use a close grip, bringing your elbows down into a narrower descent, towards the bench.
9. Your glutes and shoulder blades should maintain their contact throughout your entire lift.
10. As you descend, maintain control and bring the dumbbells down in a straight line, just above your nipple line hovering over your chest before your press back up.
11. Bring one knee up at a time, placing each dumbbell down, from the top of your lift when your set is finished.

Incline Dumbbell Bench Press: Takeaway

You should always include an incline bench variation in your strength training program, whether it's with the barbell or dumbbell bench press. The incline dumbbell bench press can improve and benefit size, strength, increasing muscle hypertrophy and support posture, balance, and core strength,.
