Standing Arm Overhead Extension

Setup

Stand with feet shoulder-width apart, keeping your core engaged and spine straight.

Movement

1. Start by holding one arm bent at chest height while extending the other straight toward the ceiling.

2. Reach actively upward as high as possible without shrugging your shoulder excessively towards your ear.

3. Return to the starting position and switch arms.

4. Maintain a steady, rhythmic pace, alternating sides to open up the shoulder girdle and upper back.
