How to Do Dumbbell Preacher Curls

1. Use a preacher curl bench, or position the back rest of a regular training bench so that it leans back slightly.
2. Grab a dumbbell, stand behind the bench, and rest your upper arm against the back rest.
3. Lower the dumbbell as far as you can, and then reverse the motion, returning to the starting position.

Commentary

The preacher curl is an effective exercise for isolating and focusing on the arm flexors. If fully extending your arm feels uncomfortable, you can avoid that position by reversing the movement earlier.
