Step-by-Step Execution Guide

1

Stand with dumbbells at sides, slight forward hip hinge, and soft bend in elbows.

2

Raise dumbbells out to sides leading with elbows until arms are parallel to floor.

3

Pour the imaginary pitcher of water slightly, keeping pinkies slightly elevated.

4

Lower with control over 2 seconds feeling continuous tension.

Common Mistakes & Form Fixes

Swinging torso or using momentum from legs.

Raising weights above shoulder level recruiting upper traps.

Biomechanical Safety & Injury Warning

Perform in the scapular plane (30 degrees forward of direct side) to protect rotator cuff.
