With the bar at waist height, stand with your feet shoulder-width apart and your knees slightly bent. Hold the bar with an overhand grip, with your hands slightly wider than shoulder-width.
Hinge forward at the hips then pull the bar towards your midsection by retracting your shoulder blades and driving your elbows back, then slowly lower the bar back down to the starting position. Your elbows should remain close to your sides throughout the movement. Keep your back straight, chest up, and shoulders down and back. Repeat for the desired number of repetitions then lock the bar at waist height.
Avoid swaying your torso or arching your back when conducting the movement.
