Position
Stand with your feet just wider than shoulder-width apart. Place one hand on your hip. With your wrist in neutral, using your other hand grasp a handle with a loose grip. Bend at your hips and slightly at your knees. Set your trunk at about a 45-degree angle from the floor. Keep your body�s weight over your ankles. Keep your elbow pointed down and slightly bent.
Technique
With your arm slightly bent, pull your shoulder blades together and down. Continue to squeeze your shoulder blades and contracting your lats while pulling your arm back. Keep your arm close to the side of your body until your elbow is almost straight down from your shoulder. Hold. Maintain a natural arch in your lower back, keeping your arm as relaxed as possible. Slowly return your arm and lats to the starting position, keeping your scapulae retracted and tension in your lats. Repeat.
