The dumbbell shrug is a great exercise for building shoulder strength, improving posture, and relieving neck and shoulder pain.

What Is Dumbbell Shoulder Shrug

Dumbbell shrugs, also known as dumbbell shoulder shrugs, are an isolation exercise that targets the upper trapezius muscle.

This exercise can be done with a medium to heavy dumbbell to increase the trap thickness.

In this exercise, you lift a pair of dumbbells using your shoulders and make a shrugging motion while keeping your arms straight.

It is a simple yet effective exercise that strengthens the shoulders, upper back, and neck muscles. They are suitable for both beginners and pros.

Dumbbell Shoulder Shrug Muscles Worked

Dumbbell shoulder shrugs primarily target the upper trapezius muscle.

However, this exercise also works several other muscles in the shoulder and upper back region, including:

1. Levator scapulae
2. Rhomboids
3. Middle Trapezius
4. Rear Deltoids
5. Rotator cuff muscles

How To Do Dumbbell Shrug

1. Stand with your feet shoulder-width apart, and hold a dumbbell in each hand with your arms extended by your sides.
2. Keep your shoulders relaxed and your core engaged.
3. Inhale and lift your shoulders towards your ears, making a shrugging motion.
4. Hold the contraction for a second or two, then exhale and lower your shoulders back down to the starting position.
5. Hold the shrug for a second, then slowly lower the dumbbells back down to the starting position.
6. Repeat for 10–12 repetitions for 2–3 sets.

Dumbbell Shrug Form and Tips

• Keeping your arms straight (slight bend in the elbows is okay).
• Avoid rolling your shoulders forward or backward.
• Focus on lifting your shoulders straight up towards your ears.
• Don’t hold your breath while performing the exercise.
• Inhale when you lower the weight and exhale when you lift.
• Engage your core and keep your back straight throughout the exercise.
• Avoid rolling the shoulders forward or back as you shrug.
• Don’t let your chin jut forward as you reach the top of the shrug. Maintain a neutral neck position.
• Adding a pause at the top of the movement can help to enhance the mind-muscle connection.
• Limit momentum and excessive jerking or bouncing of the weight.
• Resist the urge to sink your neck into your shoulders by keeping your chin up. You’ll go higher with each rep.
• Incorporate proper warm-ups, rest, and nutrition into your exercise program.

4 Best Dumbbell Shrug Variations

Once you’ve practiced the standard dumbbell shrug, consider trying these variations:

1. Incline Dumbbell Shrug

The Incline dumbbell shrug is a variation of trap dumbbell shrug exercises that strengthen the upper part of the trapezius and neck region.

This shrug variation will shift emphasis to the upper traps and the upper portion of the middle traps.

Because your chest is pressed against the bench, it will be difficult to use momentum to drive the weight up.

How To Do

1. Grab a pair of dumbbells and straddle an adjustable-incline bench with your feet flat on the floor, or position them on the bench frame to support your body.
2. Hold the dumbbells with a neutral grip at your sides and lie chest-down on an incline bench.
3. Slowly shrug your shoulders up toward your ears.
4. At the top, pause momentarily and contract hard through your traps and rhomboids.
5. Slowly lower the weights back to the starting position.

2. Seated Dumbbell Shrugs

If you want to focus on your trap muscles and not your core, try this variation of the dumbbell shrug exercise while sitting.

The seated position allows for better isolation of the upper trapezius muscles, leading to greater strength gains in this area.

How To Do

1. Grab a pair of dumbbells and sit down on the bench with your feet flat on the floor.
2. Hold the dumbbells with a neutral grip at your sides.
3. Shrug your shoulders as high as you can toward your ears.
4. At the top, pause briefly and slowly lower the weights back to the starting position.

3. Behind-the-back dumbbell shrugs

Place the dumbbells behind your back during the exercise to target your upper traps, middle traps, and rear delts slightly more than a standard dumbbell shrug.

Having the dumbbell behind you helps keep your shoulders pulled up and back rather than rounded forward.

How To Do

1. Stand up straight with your feet at shoulder width.
2. Hold a dumbbell with both hands behind your back using a pronated grip (palms facing back)
3. Raise your shoulders as high as you can, as if trying to touch them to your ears.
4. Hold momentarily, and then breathe in as you relax your shoulders back down.

4. Single Arm Dumbbell Shrugs

Performing one-arm dumbbell shrugs allows for greater isolation of the trapezius muscles on one side of the body at a time.

As the arm is free to move independently and not restricted by the other arm or a barbell, it allows for a greater range of motion than other variations.

How To Do

• Hold a dumbbell in one hand with your feet at shoulder width.
• Let the dumbbell hang down at arm’s length at your side, with your palm facing your body (neutral grip).
• Raise your shoulder as high as possible (imagine trying to touch your ear with your shoulder).
• Squeeze for a brief moment at the top, and then slowly lower all the way back down to the starting position.
• Repeat for the desired reps, then switch sides.

Dumbbell Shrug Benefits

Here are some of the benefits of dumbbell shrug exercises.

• Dumbbell shoulder shrugs are excellent for building strength and mass in the upper trapezius, deltoids, rhomboids, and other shoulder and upper back muscles.
• Weak upper back muscles can contribute to neck and shoulder pain. Shoulder shrugs can help reduce pain and discomfort by strengthening these muscles.
• Traps are tricky to build. There are only a handful of exercises that mainly target your traps. It is one of the best that targets your upper traps.
• It helps build strength in your upper body, stabilizes muscle groups, helps you stand up tall, and keeps your back straight.
• Strong shoulders and upper back muscles are essential for many athletic activities, such as throwing, lifting, and swinging.
