Dumbbell Seated Bent Arm Lateral Raise
Sit on a bench and lift the dumbbells to the sides with your elbows at a slight angle. This version targets the work specifically on the middle part of the shoulder and the muscles supporting the shoulder blade, keeping the shoulder joint movement controlled.

Why Dumbbell Seated Bent Arm Lateral Raise?
Dumbbell lateral raises with bent elbows are an excellent exercise for developing the shoulders, particularly the middle part of the shoulder. When performed seated, it effectively isolates the work to the desired muscle group, minimizing body momentum and unnecessary assistance from other stabilizing muscles. This makes the movement safer and more targeted compared to the standing version, where momentum can easily be used. The standing version can easily lead to body swaying, causing the effectiveness of the movement to focus elsewhere than on the shoulder muscles. When seated, you can better focus on the muscle feeling and keep the movement controlled from start to finish. The primary benefit of this movement is the increase in shoulder width and roundness, which gives an aesthetically pleasing V-shaped upper body. It not only improves appearance but also strengthens shoulder stability and the muscles supporting the shoulder blade, which is vital for overall shoulder health and functionality. Strong and stable shoulders help prevent injuries in other upper body movements, such as bench presses or overhead presses, and improve your posture. This exercise is excellent for both beginners who want to learn the proper shoulder muscle feeling and more experienced fitness enthusiasts looking for an effective isolation movement for their shoulder training. Its moderate difficulty level makes it accessible to many, but it still requires focus and proper technique. The movement is effective because it allows for progressive overload in a controlled manner, targeting the load directly to the middle part of the shoulder without heavy weights overly straining the neck or other assisting muscles. With dumbbells and a bench, you can easily adjust the resistance and make this part of a versatile strength training program.

How to perform
Setup
- Sit on a flat bench with your feet firmly on the floor, core tight, and chest proud.
Execution
- Exhale and lift the dumbbells to the sides to shoulder level or slightly below, with the elbows leading the movement.
- Hold at the top position for 1 second, feeling the middle part of the shoulder.
- Lower the weights in a controlled manner while inhaling, without the weights clashing against your thighs or each other.
Coaching cues
- •Keep the elbows bent throughout the movement – do not straighten the elbows at the top position.
- •Think of pouring water from jugs; a slight downward rotation of the thumbs helps find the middle part of the shoulder but avoid excessive internal rotation if it feels uncomfortable in the shoulder.
- •Maintain core support; do not sway or use momentum; choose a weight you can control for 10-15 repetitions.
Common mistakes
❌ Weights that are too heavy
Why it's wrong: Using weights that are too heavy often leads to body swaying and the use of momentum, causing the movement to not effectively target the shoulder muscles and increasing the risk of injury.
✓ Fix: Reduce the weight and focus on performing the movement slowly and controlled. The most important thing is the muscle feeling, not the amount of weight lifted.
❌ Straightening or excessive bending of the elbows
Why it's wrong: Straightening the elbows increases the lever length and unnecessarily stresses the joints, while excessive bending shortens the lever and reduces shoulder muscle activation.
✓ Fix: Keep the elbows slightly bent (about 15-30 degrees) throughout the movement. This maintains an optimal lever and protects the joints.
❌ Shrugging the shoulders
Why it's wrong: When the shoulders are shrugged upwards during the movement, the trapezius muscles take over the work instead of the shoulder muscles, reducing the effectiveness of the movement in the desired area.
✓ Fix: Keep the shoulders down and relaxed, away from the ears. Focus on lifting the weights to the side with the shoulder muscles, not the neck.
❌ Lifting the movement too high
Why it's wrong: Lifting the weights significantly above shoulder level can add unnecessary stress to the shoulder joint and rotator cuff, potentially leading to pain or injury.
✓ Fix: Lift the dumbbells only to shoulder level or slightly below. At this point, the middle part of the shoulder muscle is most effectively activated.
Frequently asked questions
How often should this exercise be done?
Generally, 2-3 times a week as part of shoulder training or upper body workouts is suitable. Remember to give the muscles enough recovery time between sets and training sessions for them to recover and grow.
Can this exercise be done standing?
Yes, but the seated version often helps better isolate the middle part of the shoulder, minimizing body momentum and assistance from other muscles. When done standing, there is a greater risk of using momentum and straining the lower back.
Why should the elbows be slightly bent?
A slight bend reduces stress on the elbow and wrist joints while maintaining an effective lever for the shoulder muscles and preventing the weights from being lifted with completely straight arms. It also helps keep the focus on the shoulder muscles.
What if I feel pain in my shoulder during the movement?
Stop the movement immediately. Check your technique, reduce the weight, or consult a professional (physiotherapist or doctor). Pain can be a sign of incorrect technique, too heavy weights, or a potential injury.
Safety tips
- Always start with light weights and focus on perfect technique before adding weights.
- Keep the movement controlled during both the lifting and lowering phases; avoid dropping the weights down quickly.
- Avoid shrugging the shoulders and rounding the back; keep the body stable on the bench.
- Listen to your body – if you feel sharp pain, stop the movement and reassess the situation.
- Warm up the shoulders and shoulder joints carefully before starting the movement with dynamic stretches.
