Dumbbell Seated Bent Over Alternate Rear Delt Fly
Dumbbell Seated Bent Over Alternate Rear Delt Fly Exercise Description
The Dumbbell Seated Bent-Over Alternate Rear Delt Fly targets the posterior deltoids through controlled horizontal abduction of the shoulder while you maintain a stable, hinged torso. Sitting reduces lower-body sway so you can focus on precise shoulder movement without using momentum. Primary work is done by the posterior deltoid; the middle and lower trapezius and rhomboids assist with scapular control, and the rotator cuff helps stabilize the glenohumeral joint. Performing the arms one at a time emphasizes consistent path and range on each side. The goal is smooth, shoulder-driven arcs with a neutral spine, steady torso, and relaxed neck and upper traps. Expect a moderate range of motion, stopping when the upper arm reaches shoulder level without the shoulder rolling forward.

How To Do The Dumbbell Seated Bent Over Alternate Rear Delt Fly Exercise
‘- Sit on the bench edge, feet flat and planted.
– Hold dumbbells with a neutral grip at your sides.
– Hinge at the hips until chest is near-thigh; keep a neutral spine.
– Brace lightly; keep neck long and gaze at the floor.
– Let arms hang under shoulders; maintain soft elbows and neutral wrists.
– Set shoulders down and back slightly; avoid shrugging.
– Lift one dumbbell out and slightly back to shoulder height.
– Lead with the elbow; keep the forearm aligned with the hand.
– Gently draw the shoulder blade toward the spine at the top.
– Lower with control; keep the torso still and ribs stacked.
– Alternate sides, matching path and range on each arm.
– Stay in a comfortable range; stop before the shoulder rolls forward.
Dumbbell Seated Bent Over Alternate Rear Delt Fly Tips
‘- Sit on the edge of the bench with feet flat and firmly planted to keep your base stable.
– Hinge at the hips until your chest is near your thighs while keeping a neutral spine.
– Keep your neck long and eyes on the floor to avoid tensing your neck and upper traps.
– Let your arms hang directly under your shoulders with soft elbows and neutral wrists before lifting.
– Set your shoulders slightly down and back and avoid shrugging before each rep.
– Lead the lift with your elbow, keeping your forearm in line with your hand as you raise the dumbbell.
– Lift the dumbbell out and slightly back only to shoulder height, then pause to gently draw the shoulder blade toward your spine.
– Lower the dumbbell with control, keeping your torso still and ribs stacked.
– Alternate sides, matching the same path and range of motion on each arm.
– Stay within a comfortable range and stop the lift before your shoulder begins to roll forward.
Dumbbell Seated Bent Over Alternate Rear Delt Fly Beginner Introduction
The Dumbbell Seated Bent-Over Alternate Rear Delt Fly is a seated dumbbell exercise that highlights the rear shoulders while the torso stays leaned forward and quiet. Because the body rests on a bench rather than standing, leg drive and extra movement through the lower body are reduced, directing the effort into the shoulders instead of momentum. As the weight moves, the rear shoulders handle most of the workload, with the upper back muscles around the shoulder blades and the rotator cuff assisting in guiding and steadying each repetition.
The arms travel one at a time in a controlled, sweeping path slightly out to the side and back until the upper arm lines up roughly with the shoulder. The trunk remains fixed, with the spine held in a natural curve and the ribs calm, so the motion comes mainly from the shoulder joint and shoulder blade. The neck and upper traps stay relaxed rather than shrugging. Alternating sides encourages even movement quality on both arms, matching the height and route of each lift within a comfortable, moderate range.
