This exercise is best done with a special preacher curl bench, but you can do this without it with a little modification. Sit at the end of the weight bench, and place something such as a firm pillow or a few pillows under your armpits on your lap. Hold the curl bar in your hands with palms facing upward. Don’t hunch over the pillow, sit as straight as you can.
Using a shoulder width grip, grasp the bar in both hands. Curl the bar upward in an arc. Be careful not to swing or rock to get the bar moving. You need to be using your muscles to lift the weight, not momentum. The goal of this exercise is to work the biceps.
Bring the bar up to your chin keeping in mind that the resistance is greatest during the beginning of the lift. Lower the bar slowly working the muscle on the way down as well. You can also do this with dumbbells or work one arm at a time.
