Kneel down on one knee and rest your same-side arm on the incline bench. Hold the dumbbell in a vertical position and get ready to start the movement. This is your starting position.
Lower the dumbbell down until it almost touches the bench. Don't lower it completely because you should always keep tension in your biceps for maximum effectiveness. Then, raise the dumbbell back up until your forearm is almost completely vertical. Then, do the same with your other arm. Finally, repeat entire movement for the desired or prescribed number of repetitions.
