Single Arm Dumbbell Shrug

Instructions for proper form

1. Stand upright with your feet shoulder-width apart and hold one dumbbell in your right hand at your side with your arm fully extended. 2. Keep your torso straight and core engaged. 3. Elevate your shoulder towards your ear by squeezing your upper trapezius. 4. Hold the top position for a moment, then lower your shoulder back down to the starting position. 5. Repeat for the desired number of repetitions before switching to the left arm. Maintain a neutral grip throughout the movement.

Common mistakes to avoid

1. Avoid rolling the shoulder; the movement should be an up-and-down motion. 2. Don’t use momentum to lift the weight; focus on controlled movements. 3. Ensure you are not leaning or twisting your torso during the exercise. 4. Avoid letting your arm move forward or backward; it should stay close to your body.
