Exercise guide

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.

Muscles worked

Primary

Secondary

  • Erector spinae
  • Rhomboids
  • Serratus anterior

Equipment

  • Dumbbell

Setup

  1. Set an incline bench to a 30-45 degree angle.
  2. Lie prone (face down) on the bench with your chest firmly against the pad and feet planted securely on the floor.
  3. 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

  1. 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.
  2. Pause for a split second at the peak of the movement to maximize contraction in the rear deltoid.
  3. Inhale as you slowly lower the weight back to the starting position with a controlled 2-second eccentric phase.
  4. 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.
