Exercise guide

Prone Y Raise

  • Beginner
  • Compound
  • Rep-based
  • Back
  • Shoulders
  • Upper arms

This isolation exercise targets the lower trapezius and posterior deltoids, essential for improving shoulder stability and correcting rounded-shoulder posture. By performing this on an incline, you maximize the range of motion and tension on the upper back muscles.

Setup

  1. Set an incline bench to a 30 to 45-degree angle.
  2. Lie prone (face down) with your chest supported by the bench and your head clearing the top edge.
  3. Extend your arms straight down toward the floor with your thumbs pointing upward in a neutral grip.
  4. Plant your toes firmly on the ground to stabilize your lower body and maintain a neutral spine.

How to do it

  1. Raise your arms diagonally forward at a 45-degree angle to your body to form a 'Y' shape.
  2. Exhale as you lift your arms until they are in line with your torso, keeping your elbows fully extended.
  3. Pause for one second at the top of the movement to emphasize the peak contraction in the lower traps.
  4. Inhale as you slowly lower your arms back to the starting position with a controlled 2-second tempo.

Form checklist

  • Keep your thumbs pointing toward the ceiling throughout the entire movement.
  • Maintain a neutral neck by looking slightly down at the floor rather than straight ahead.
  • Avoid shrugging your shoulders toward your ears; keep your shoulder blades pulled down.
  • Ensure your chest stays in contact with the bench; do not arch your lower back to gain height.

Pro tips

  • Initiate the movement by depressing your shoulder blades toward your back pockets before your arms begin to move.
  • Focus on 'reaching' your hands as far away from your body as possible to maximize scapular upward rotation and lower trap engagement.

Make it harder

  • Perform the movement with a 3-5 second isometric hold at the top of each repetition.
  • Incorporate a slower 4-second eccentric (lowering) phase to increase time under tension for the posterior chain.
