smith back shrug

Stand with your feet shoulder-width apart and your knees slightly bent. Grasp the barbell with an overhand grip, hands slightly wider than shoulder-width apart. Keep your arms straight and allow the barbell to hang in front of your thighs. Lift your shoulders straight up towards your ears, squeezing your traps at the top. Hold for a moment, then lower your shoulders back down to the starting position. Repeat for the desired number of repetitions.
