Stand with feet shoulder-width apart, holding a resistance band with both hands at chest height.
Arms should be straight out in front of you, hands about shoulder-width apart on the band.
Keep your arms straight and pull the band apart by moving your hands out to the sides.
Squeeze your shoulder blades together as you pull, bringing the band toward your chest.
Hold the stretched position briefly, feeling the contraction in your rear deltoids and upper back.
Slowly return to the starting position with control.
Keep your core engaged and avoid arching your lower back throughout the movement.
Repeat for desired repetitions.
