Sit on the floor with legs extended and secure a resistance band around your feet. Grasp the band handles with arms extended, maintaining good posture with a slight forward lean from the hips. Pull the band toward your torso by driving your elbows backward while keeping your back straight, squeezing your shoulder blades together at the end of the movement. Hold briefly at the contracted position, then slowly return to the starting position with control. Throughout the exercise, keep your core engaged, shoulders relaxed away from your ears, and focus on using your back muscles rather than just your arms to perform the pulling motion.
