Performing the: A Step-by-Step Tutorial Reverse grip Preacher Curl
Grab an EZ curl bar or a straight bar with your palms facing towards you (a reverse grip), and make sure your hands are shoulder-width apart.
While keeping your upper arms and elbows stationary on the bench, slowly lift the bar until your arms are fully contracted and the biceps are fully contracted at the top.
Hold the contracted position for a second as you squeeze your biceps.
Gradually lower the bar back to the starting position, ensuring that you fully extend your arms and feel the stretch in your biceps.
