1
Stand upright with feet shoulder-width apart, arms extended laterally at shoulder height, palms facing forward or slightly downward. Maintain neutral spine and engage core throughout the movement.
2
Begin with arms extended out to sides in a T-position. Ensure shoulders are retracted and scapulae stable. Take a deep breath to prepare for the movement.
3
Slowly lower the arms in a wide arc by adducting the shoulders, bringing hands together in front of the chest in a controlled manner. This lengthens the pectoral muscles as they move through flexion.
4
Press the arms back out to the starting position by performing horizontal adduction of the shoulders, engaging the chest muscles to drive the arms outward. Return to full arm extension with control.
