1
Stand upright with feet shoulder-width apart, arms at sides, neutral spine, chest up, and core engaged with no external load or minimal resistance
2
Position arms slightly away from body with a slight bend in elbows, palms facing down or neutral, shoulders retracted and depressed
3
Slowly raise both arms out to the sides in a controlled manner, maintaining slight elbow bend, lifting arms to approximately shoulder height or slightly below, creating a smooth arc motion
