Lie on a flat bench with a barbell held above your chest and arms extended. Slowly lower the barbell behind your head in a controlled arc until you feel a deep stretch in your lats and chest. Hold the barbell at the bottom position with tension in the muscles, keeping your core braced and elbows slightly bent. Maintain the hold for the desired time, then carefully raise the bar back to the start position while keeping muscles engaged.
