Grasp a barbell with an overhand grip that is slightly less than shoulder width. The bar should be resting on the top of your thighs with your arms extended and a slight bend in your elbows. Your back should also be straight.
Lift the bar, raising your elbows up and to the side. Keep the bar close to your body as you raise it. Continue to lift the bar until it nearly touches your chin.
Lower the bar back down slowly to the starting position. Inhale as you perform this portion of the movement.
Variations: This exercise can also be performed using a straight bar attached to a low pulley and it can also be performed using dumbbells.
