Dumbbell Incline Single Arm Y Raise
- Intermediate
- Compound
- Rep-based
- Back
- Shoulders
- Upper arms
This unilateral isolation exercise targets the lateral and anterior deltoids while heavily engaging the lower and middle trapezius for scapular stability. The chest-supported incline position eliminates momentum, ensuring the shoulder and upper back perform the work through a specific 'Y' path of motion.

Setup
- Set an incline bench to an angle between 45 and 60 degrees.
- Lean your chest against the backrest with your feet firmly planted on the floor for stability.
- Hold a light dumbbell in one hand using a neutral grip with your thumb pointing toward the ceiling.
- Let the working arm hang straight down, positioned slightly forward of your shoulder line.
How to do it
- Exhale as you raise the dumbbell diagonally upward and outward at a 45-degree angle from your torso to form a 'Y' shape.
- Continue the lift until your arm is roughly in line with your ear, keeping the elbow straight but not locked.
- Pause for a second at the top of the movement to emphasize the contraction in the deltoids and lower traps.
- Inhale as you slowly lower the dumbbell back to the starting position with a controlled 2-3 second tempo.
Form checklist
- Keep your chest firmly pressed against the bench to prevent torso rotation or arching.
- Avoid shrugging the shoulder toward your ear; keep the scapula depressed and stable.
- Maintain a neutral neck by looking slightly downward rather than craning your head up.
- Ensure the movement follows a 45-degree diagonal path, not directly to the front or side.
Pro tips
- Focus on 'reaching' the dumbbell toward the corner of the room to maximize lateral deltoid tension and scapular upward rotation.
- Initiate the movement by thinking about moving your shoulder blade first to better engage the lower trapezius fibers.
Make it harder
- Incorporate a 3-second isometric hold at the peak of each repetition to increase time under tension.
- Slow the eccentric phase to 4-5 seconds to challenge the stabilizing muscles of the rotator cuff.
