About this exercise

The Dumbbell Incline Single Arm Y-Raise is a prone isolation exercise performed on an incline bench that targets the posterior deltoid and lower trapezius. Raising one dumbbell diagonally up and out in a Y-shape mimics scapular upward rotation and reinforces healthy shoulder mechanics.

How to Perform

  • Set an adjustable bench to a low incline (roughly 30–45 degrees) and lie face down with your chest supported
  • Hold a light dumbbell in one hand with your arm hanging straight down, palm facing inward
  • Keep your working shoulder blade depressed and slightly retracted before initiating the lift
  • Raise the dumbbell diagonally forward and out to approximately a 45-degree angle from your body, forming a Y shape
  • Lift until your arm is roughly in line with your torso or slightly above, without shrugging your shoulder
  • Slowly lower the dumbbell back to the hanging position with control
  • Complete all reps on one side before switching to the other arm
