Dumbbell Neutral Grip Alternating Rear Lateral Ra
- Intermediate
- Compound
- Rep-based
- Back
- Shoulders
- Upper arms
- Waist
This chest-supported variation isolates the posterior deltoids and middle trapezius by eliminating momentum and providing a stable base. The neutral grip and alternating pattern allow for intense focus on the mind-muscle connection and unilateral stability.

Setup
- Set an incline bench to a 30-45 degree angle.
- Lie prone (face down) on the bench with your chest firmly against the pad and feet planted securely on the floor.
- Hold a dumbbell in each hand with a neutral grip (palms facing each other) and arms hanging straight down toward the floor.
How to do it
- Exhale and raise one arm out to the side in a wide arc until it is level with your shoulder, keeping a slight bend in the elbow.
- Pause for a split second at the peak of the movement to maximize contraction in the rear deltoid.
- Inhale as you slowly lower the weight back to the starting position with a controlled 2-second eccentric phase.
- Repeat the movement with the opposite arm, alternating sides until the set is complete.
Form checklist
- Keep your chest glued to the bench throughout the set to prevent swinging.
- Maintain a neutral neck by looking slightly down at the floor.
- Lead the movement with your elbows rather than pulling with your hands.
- Ensure the arm moves directly out to the side, not back toward the hips.
Pro tips
- Imagine pushing the dumbbells away toward the side walls to maximize lateral tension on the rear deltoid.
- Focus on keeping the shoulder blades depressed to minimize excessive upper trap involvement.
Make it harder
- Incorporate a 2-second isometric hold at the top of every repetition.
- Slow the eccentric (lowering) phase to 4 seconds to increase time under tension.
