Dumbbell Lying One Arm Rear Lateral Raise
Dumbbell Lying One Arm Rear Lateral Raise Exercise Description
The Dumbbell Lying One Arm Rear Lateral Raise trains horizontal shoulder abduction with emphasis on the posterior deltoid, while the middle trapezius, rhomboids, and rotator cuff (infraspinatus, teres minor) assist with scapular control. Performing it lying on your side reduces torso cheating and helps you isolate the rear shoulder through a controlled range. The goal is to move primarily at the glenohumeral joint while keeping the scapula lightly retracted and depressed for a stable shoulder complex. A neutral to slightly externally rotated forearm (thumb subtly turned upward) is a common cue that encourages clean mechanics at the top of the lift. Maintain a neutral spine and neck, avoid shrugging, and keep the elbow softly bent so the wrist, elbow, and shoulder move together in a smooth arc.

How To Do The Dumbbell Lying One Arm Rear Lateral Raise Exercise
‘- Lie on your side on the floor, head supported by your lower arm; knees slightly bent for balance.
– Hold a dumbbell in the top hand with a neutral grip; let the arm hang slightly in front of your chest.
– Set the shoulder: gently draw the shoulder blade down and back; keep ribs stacked and neck neutral.
– With a soft elbow and wrist neutral, raise the arm in an arc until the upper arm is roughly in line with your shoulder.
– Keep the forearm neutral or thumb slightly up; do not shrug or rotate your torso.
– Pause briefly at the top with the shoulder blade controlled (retracted/depressed).
– Lower the dumbbell slowly until the hand returns just in front of your chest, keeping the shoulder centered.
– Switch sides and repeat, using the same controlled range that allows the shoulder to stay stable.
Dumbbell Lying One Arm Rear Lateral Raise Tips
‘- Lie fully on your side with your head supported by your lower arm to keep your neck neutral.
– Bend your knees slightly to create a stable base and reduce torso movement.
– Let the working arm start hanging slightly in front of your chest with a neutral grip.
– Gently draw your shoulder blade down and back before you lift, keeping your ribs stacked.
– Maintain a neutral spine and neck throughout; avoid rotating your torso as you raise the weight.
– Keep a soft bend in your elbow so the wrist, elbow, and shoulder travel together in one smooth arc.
– Lift only until your upper arm is roughly in line with your shoulder, focusing on movement at the shoulder joint.
– Keep the forearm neutral or with the thumb slightly up to encourage clean mechanics at the top.
– Do not shrug; keep the shoulder blade lightly retracted and depressed as you raise and pause.
– Lower the dumbbell slowly back to just in front of your chest, keeping the shoulder centered and controlled.
Dumbbell Lying One Arm Rear Lateral Raise Beginner Introduction
The Dumbbell Lying One Arm Rear Lateral Raise is a side-lying free-weight move that targets the back of the shoulder while also engaging the upper back and the smaller stabilizing muscles around the joint. Because the body rests on the floor, the trunk has less chance to swing, which places more responsibility on the shoulder to guide the weight through the motion. The arm travels out away from the body roughly in line with the floor, so the main action happens at the shoulder rather than through twisting or arching elsewhere.
In this position, the person lies on one side with the upper hand holding a dumbbell and the arm starting slightly in front of the chest. The weight moves in a smooth arc until the upper arm is roughly level with the shoulder, with a gentle bend at the elbow and a relaxed, straight wrist. A “handshake” grip or a slight turn of the thumb upward encourages a clean path. Throughout, the shoulder blade settles toward the ribcage for steadiness, the neck and spine stay in a comfortable line, and the torso remains quiet as each side works through a slow, deliberate range.
