How to do it
- Set an incline bench and rest your chest on the upper pad with both feet planted wide.
- Hold one dumbbell in the working hand and let that arm hang straight down.
- Brace the free forearm across the top of the pad so the torso stays still.
- Keep a slight bend in the working elbow and raise the dumbbell out to the side.
- Stop when the upper arm reaches about shoulder height without shrugging.
- Lower under control to a full hang, finish the set, then switch arms.
Common mistakes
- Pulling the dumbbell toward the hip, which turns the raise into a row.
- Lifting the chest off the pad to swing the weight up.
- Bending the elbow too much, which shortens the lever and cuts deltoid load.
- Raising the arm forward of the torso so the lateral deltoid takes over.
