Zottman Preacher Curl (Dumbbell)
Also called Zottman Preacher Curl, DB Zottman Preacher Curl
How to do it
Grab a dumbbell in each hand and place the upper arms on top of the preacher bench with the arms extended and palms facing up. Curl the bells up with a supinated grip, rotate the wrists to palms-down at the top, then lower slowly in that pronated position — the slow pronated descent is the point of the exercise. Rotate back to palms-up at the bottom before the next rep.
