Exercise guide
Lying Prone Y Raise
- Intermediate
- Isolation
- Rep-based
- Back
- Shoulders
This isolation movement targets the lower trapezius and posterior deltoids to improve shoulder stability and postural alignment. By lifting the weights in a 'Y' shape, you maximize the recruitment of the mid-back muscles while minimizing upper trap dominance.

Setup
- Lie face down (prone) on a flat bench or a mat on the floor with your legs extended.
- Hold a pair of light dumbbells with a neutral grip, palms facing each other and thumbs pointing toward the ceiling.
- Position your arms out at a 45-degree angle from your torso so your body forms a 'Y' shape.
- Tuck your chin slightly to keep your neck in a neutral position throughout the set.
How to do it
- Exhale as you lift the dumbbells toward the ceiling, keeping your arms completely straight.
- Squeeze your shoulder blades down and together at the top of the movement, focusing on the lower traps.
- Inhale as you slowly lower the weights back to the starting position under full control.
- Maintain a controlled 2-1-2 tempo, avoiding the use of momentum or swinging.
Form checklist
- Keep your thumbs pointing up to ensure external shoulder rotation.
- Avoid shrugging your shoulders toward your ears; keep the traps depressed.
- Keep your chest and hips firmly pressed into the bench or floor.
- Do not arch your lower back to gain height; the movement should come from the shoulders and mid-back.
Pro tips
- Think about reaching your hands 'long' toward the corners of the room to better engage the serratus and lower traps.
- Initiate the movement by depressing your scapula before the arms even move to ensure the mid-back is doing the work.
Make it harder
- Add a 3-second isometric hold at the peak of the contraction to increase time under tension.
- Perform the exercise on an incline bench set to 30 degrees to increase the range of motion and resistance profile.
