Y-Raise
How to Do an Incline Dumbbell Y-Raise
Set an incline bench to a comfortable low-to-moderate angle and lie chest-down with light dumbbells in your hands.
Let the arms hang below the shoulders with a small elbow bend and thumbs angled generally upward.
Brace gently against the bench and keep your neck in line with your torso.
Raise both arms forward and outward on a diagonal so your arms form a Y rather than a T.
Let the shoulder blades rotate and move naturally without aggressively shrugging toward the ears.
Pause briefly at the highest position you can reach without lifting your chest or arching your back.
Lower the dumbbells slowly to the hanging start position and repeat with the same diagonal path.
Form Check & Technique
DO THIS (Technique Tips)
- Use very light dumbbells
- Think diagonal Y rather than straight sideways
- Keep the chest supported
- Reach long through the arms instead of shrugging
- Pause briefly at the top without forcing height
AVOID THIS (Common Mistakes)
- Turning the Y into a straight T-shaped rear-delt fly
- Using dumbbells that are too heavy
- Shrugging the shoulders toward the ears
- Lifting the chest off the bench
- Bending the elbows excessively to shorten the lever
- Raising the arms beyond a controllable range
- Rushing the eccentric
About Y-Raise
The dumbbell Y-raise lifts the arms diagonally overhead so they form a Y with the torso. It is commonly used to train controlled shoulder-blade upward rotation and lower-trapezius function while the posterior deltoid and other scapular muscles assist. The canonical version here uses a chest-supported incline bench to limit body momentum.
Y-Raise Muscles Worked
Y-raise variations are frequently studied for lower-trapezius activation because the diagonal overhead arm path combines shoulder elevation with scapular upward rotation.
- The posterior deltoid contributes, but this is not the same horizontal-abduction pattern as a rear-delt fly.
Sets & Reps Guidance
Technique / Learning
2-3 sets of 10-15 slow reps with minimal load while learning the diagonal arm path.
Strength Focus
2-3 sets of 8-12 reps with strict control; this is an accessory movement rather than a maximal strength lift.
Muscle Growth (Hypertrophy)
2-4 sets of 10-20 reps using a light load that allows the Y path and shoulder-blade motion to stay consistent.

Y-Raise vs Rear-Delt Fly
A rear-delt fly moves the arms mostly out to the sides in a T-like horizontal-abduction path. A Y-raise angles the arms forward and overhead, creating a different scapular and shoulder demand.
Why the Lower Traps Matter in a Y-Raise
The lower trapezius assists upward rotation and posterior positioning of the scapula as the arms elevate. EMG research supports its involvement but should not be turned into claims that Y-raises uniquely build or rehabilitate the lower traps.
What Bench Angle Should You Use?
Use an incline that lets the chest stay supported and the arms clear the floor. Bench angle changes the relationship with gravity, so consistency matters more than one supposedly perfect setting.
Should Your Thumbs Point Up?
A thumbs-up or neutral-to-external-rotation position is a practical default because it usually matches the Y path comfortably. Do not force shoulder rotation beyond your natural range.
Standing vs Chest-Supported Y-Raise
Standing or hinged versions exist, but chest support removes much of the opportunity for torso momentum. If the Need.fit media shows a standing version, the visible HowTo should be adjusted to match the media before indexing.
