Towel Standing Internal Slide Rotation

Stand upright next to a sturdy box or table, placing a small towel on the surface.

Rest the outer edge of your forearm on the towel with your elbow bent at a ninety-degree angle.

Keep your torso steady and gently slide your forearm outward across the towel to start the movement.

Slowly reverse the motion by sliding your forearm inward toward your centerline, feeling your shoulder rotate internally.

Maintain a controlled pace and smooth motion throughout each repetition.
