Dumbbell Lying One Arm Deltoid Rear

Description

How to Do Dumbbell Lying One Arm Deltoid Rear

1. 1
   Setup

   Lie sideways on a flat bench, holding a dumbbell in one hand with your palm facing your body and arm extended towards the floor.

2. 2
   Setup

   Position your non-working hand on the bench for stability, ensuring your torso is stable and parallel to the floor.

3. 3

   Keeping a slight bend in your elbow, slowly raise the dumbbell in an arc up and away from your body until your arm is roughly parallel to the floor.

4. 4

   Focus on squeezing your rear deltoid at the top of the movement, imagining you're pulling with your elbow, not your hand.

5. 5

   Slowly lower the dumbbell back to the starting position with control, maintaining tension on the rear deltoid throughout the entire range of motion.

6. 6

   Exhale as you lift the dumbbell and inhale as you lower it, maintaining a steady breath rhythm.

Tips

• Maintain a slight bend in your elbow throughout the movement to protect the joint and keep tension on the target muscle.
• Focus on initiating the movement from your rear deltoid, not your traps or biceps, by imagining you're pulling your elbow up and back.
• Control both the concentric (lifting) and eccentric (lowering) phases to maximize muscle engagement and prevent momentum from taking over.
• Keep your core engaged to prevent your torso from rotating or arching excessively, which helps isolate the rear deltoid.

Common Mistakes

• ×Using excessive momentum or swinging the weight reduces rear deltoid activation; instead, use a controlled, deliberate motion to lift and lower the dumbbell.
• ×Shrugging your shoulders or engaging your traps too much shifts focus away from the rear deltoids; instead, keep your shoulders down and back throughout the movement.
• ×Lifting the dumbbell too high or with a locked elbow can strain the shoulder joint; instead, stop when your arm is parallel to the floor with a slight elbow bend.
