Hang from a pull-up bar with an overhand grip, hands shoulder-width apart, arms fully extended.

Allow your body to hang relaxed (dead hang).

Without bending your elbows, initiate the movement by depressing and retracting your shoulder blades (pulling them down and back).

Feel the contraction in your upper back as your body lifts slightly.

Hold the top position briefly, then slowly release back to the dead hang position.

Repeat for the desired number of repetitions.
