Horizontal abduction shoulder dumbell

Purpose of the exercise

Aims to strengthen the posterior shoulder (posterior deltoid), rhomboidei and lower/middle trapezius. Improves shoulder blade stability, postural control and scapular coordination. Supports injury prevention and optimal shoulder function during overhead and pulling movements.

Supplies

• Dumbbell (light to moderate resistance)

• Exercise bench (optional, for prone version)

• Flat and stable surface

Starting position

1. Lie on a bench in prone position or bend forward from the hips

2. Keep torso stable and back neutral

3. Let the arm with dumbbell hang straight down

4. Elbow slightly bent

5. Shoulder blade in neutral position

6. Core tightened

Implementation

1. Move the arm sideways backwards in the horizontal plane

2. Pull the scapula back in a controlled manner

3. Move until the arm is about shoulder height

4. Hold tension briefly at the top of the movement

5. Lower the arm slowly and in a controlled manner

6. Maintain torso stability throughout movement

7. Repeat controlled and switch arms if unilateral

Points of interest

✓ Move in a controlled manner without momentum
✓ Focus on shoulder blade activation
✓ Keep the neck relaxed
✓ Core tightened for torso stability
✓ Move within a pain-free range

✗ Shoulders raised towards ears
✗ Swinging the weight
✗ Excessive turning of the trunk
✗ Using too heavy a dumbbell
✗ Ignoring pain in shoulder or neck

When this exercise?

Horizontal abduction shoulder with dumbbell is used to strengthen the posterior shoulder and shoulder blade muscles and improve scapular stability. The exercise is relevant within rehabilitation for shoulder pain, postural problems or reduced shoulder control. In addition, the exercise is often used in preventive programmes for athletes who perform a lot of overhead or pulling movements.

Due to the relatively low load and controlled execution, the exercise is suitable in various phases of training and recovery, if performed pain-free. Application, loading and progression should always take place in consultation with a physiotherapist or other qualified professional to ensure that the exercise is safe and tailored to the individual's load capacity, symptoms and recovery status.
