Grip a pull-up bar with an overhand grip, hands shoulder-width apart or slightly wider.

Hang from the bar with arms fully extended.

Engage core and back muscles to create a slight arch in your body (chest forward, legs slightly back).

Actively depress and retract shoulder blades (pull them down and back).

Maintain this arched position with active shoulders.

Hold for the desired duration, breathing steadily.

Release grip carefully.
