Dumbbell Lying Delt Row On Rack
- Intermediate
- Compound
- Rep-based
- Back
- Shoulders
This chest-supported row variation isolates the rear deltoids and trapezius by eliminating momentum and lower back strain. Using a bench for support ensures strict mechanics, making it a premier movement for posterior shoulder hypertrophy.

Setup
- Position a flat bench inside a power rack, ensuring the bench is high enough to allow for full arm extension without the dumbbells hitting the floor.
- Place the dumbbells on the rack pins or the floor directly under your shoulder line.
- Lie face down (prone) on the bench with your chest supported and your feet braced firmly on the floor for stability.
- Grip the dumbbells with a wide overhand grip (palms facing your feet).
How to do it
- Pull the dumbbells upward by driving your elbows out wide to the sides, keeping them at a 90-degree angle relative to your torso.
- Exhale as you pull and focus on squeezing your shoulder blades together at the top of the movement.
- Inhale as you slowly lower the dumbbells back to the starting position using a controlled 2-3 second tempo.
- Maintain a full stretch at the bottom without letting the weights rest on the floor or rack.
Form checklist
- Keep elbows flared out wide to prioritize the deltoids over the latissimus dorsi.
- Ensure your chest remains in constant contact with the bench to prevent swinging.
- Maintain a neutral neck position by looking slightly down at the floor.
- Avoid shrugging the shoulders toward the ears; keep the scapula depressed.
Pro tips
- Imagine you are trying to 'pull the dumbbells apart' rather than just pulling them up to increase rear delt fiber recruitment.
- Use a thumbless 'suicide' grip to reduce forearm and bicep involvement, forcing the upper back to do the work.
Make it harder
- Add a 2-second isometric hold at the peak of the contraction to maximize trapezius activation.
- Perform a '1.5 rep' style where you pull to the top, lower halfway, pull back to the top, and then lower fully.
