The dumbbell shrug is a trapezius exercise that involves shrugging your shoulders while holding a pair of dumbbells.
The exercise can also be performed with a barbell, in which case it is called a barbell shrug.
Here are the steps to properly perform single-arm dumbbell shrugs:
- Stand up straight with your feet shoulder-width apart. Hold a dumbbell in one hand at your side with your palm facing inwards.
- Keep your arm extended but not locked out, with a slight bend in the elbow. Maintain good posture - keep your chest up and core braced.
- Initiate the movement by shrugging the shoulder of the working arm straight up towards your ear. Focus on lifting the dumbbell straight up without leaning or swinging.
- At the top of the movement, pause briefly and fully contract the trap muscle. You should feel a strong squeeze in the upper trap.
- Slowly lower the dumbbell back down to the starting position in a controlled motion. Don't let your shoulder drop down between reps.
- Complete all reps on one side before switching to the other arm. Alternate sides evenly.
Tips:
- Keep your core tight and avoid excessive arching in your back.
- Use your free hand to help stabilize your torso if needed.
- Start light and focus on the mind-muscle connection and proper form.
- Breathe out as you shrug the weight up.
Here are some of the common mistakes to avoid when performing single-arm dumbbell shrugs:
-
Excessive Momentum and Swinging
It's tempting to use momentum to heave the weight up, but this reduces trap activation and can lead to injury. Focus on controlled, deliberate shrugging motions. -
Arching the Back
Arching the back excessively to try and lift the weight higher takes the focus off the traps. Keep your core braced and maintain a neutral spine position. -
Shrugging Too High
Trying to shrug the weight all the way up towards your ear can put unnecessary strain on the shoulders. Aim to lift the weight up about 3-4 inches. -
Not Squeezing the Traps
Make sure to really contract and squeeze the trap muscle at the top of the movement. Don't just lift the weight, focus on activating the traps. -
Uneven Shoulder Movement
Letting one shoulder shrug higher than the other can create muscular imbalances. Keep your shoulders even and lift the weight straight up. -
Not Controlling the Descent
Lowering the weight too quickly or letting it drop down can eliminate the tension on the traps. Maintain control through the entire range of motion. -
Gripping Too Tightly
An overly aggressive grip can fatigue the forearms and hands before the traps. Keep a firm but relaxed grip. -
Not Bracing the Core
Failing to brace the core can cause your torso to twist or sway, reducing the effectiveness of the exercise.
Start with a weight you can control and gradually increase over time. Engage the traps fully on each rep for maximum effectiveness. Proper single-arm shrug form is key to targeting the traps efficiently.
