Exercise guide

Lying Prone W Raise

  • Intermediate
  • Compound
  • Rep-based
  • Back
  • Chest
  • Upper arms
  • Waist

The Lying Prone W Raise is a highly effective posterior chain exercise that isolates the rear deltoids, rhomboids, and middle traps to improve shoulder stability and postural alignment. By combining scapular retraction with external rotation, it builds upper back density while reinforcing healthy shoulder mechanics.

Muscles worked

Primary

  • Pectorals
  • Triceps

Secondary

  • Abs
  • Lats
  • Serratus anterior

Equipment

  • Dumbbell

Setup

  1. Lie face down on a flat bench or floor with your forehead resting down to maintain a neutral spine.
  2. Hold a light dumbbell in each hand with a neutral grip, palms facing inward.
  3. Bend your elbows to 90 degrees and pull them away from your torso to form a 'W' shape.

How to do it

  1. Exhale as you lift the dumbbells toward the ceiling by retracting your shoulder blades and rotating your shoulders back.
  2. Keep your elbows bent at 90 degrees, ensuring your hands and elbows rise simultaneously to maintain the 'W' shape.
  3. Pause for one second at the top of the movement to emphasize the peak contraction in the mid-back.
  4. Inhale as you slowly lower the weights back to the starting position with a controlled 2-second eccentric phase.

Form checklist

  • Keep your forehead down to avoid neck strain and maintain a neutral spine.
  • Ensure the movement is driven by the shoulder blades rather than just the arms.
  • Maintain a consistent 90-degree bend in the elbows throughout the entire set.
  • Keep your core engaged and hips pressed into the surface to prevent lower back arching.

Pro tips

  • Focus on 'pulling' with your mid-back muscles rather than just lifting the weights with your hands.
  • Think about rotating your thumbs toward the ceiling at the top of the rep to maximize external rotation and rear delt engagement.

Make it harder

  • Incorporate a 3-5 second isometric hold at the top of every repetition.
  • Perform the movement on a slight incline bench (15-30 degrees) to increase the resistance curve at the peak of the movement.
