Lie flat on a bench with your head at one end and your feet on the ground. Hold the barbell with a pronated grip (palms facing away from you) and extend your arms straight above your chest. Keeping your arms straight, lower the barbell behind your head in an arc-like motion until you feel a stretch in your lats. Pause for a moment, then reverse the motion and press the barbell back to the starting position above your chest. Repeat for the desired number of repetitions.
