The banded lateral rotation exercise targets the muscles of the shoulders and upper back, particularly the rotator cuff muscles. Start by attaching a resistance band to a sturdy anchor at waist height. Stand perpendicular to the anchor point, holding the band in front of you with your arms extended and palms facing each other. Keep your core engaged and slowly rotate your arms away from the anchor point, stretching the band while maintaining control. Return to the starting position and repeat for the desired number of repetitions, then switch sides. Focus on maintaining proper form and controlling the movement to effectively engage the targeted muscles.
