Exercise Advice: Lie flat on your back on a flat bench. Using an EZ Curl bar, begin by holding the bar above your chest with your elbows slightly bent. Slowly lower the barbell back so as to stretch your arms (and the barbell) back behind your head as far as you can reach. Your arms and the barbell will actually go behind/above your head and will drop down below the bench, this will really give you a great stretch! Return the bar to the start position slowly, focusing on keeping your elbows locked in the slightly bent position.
