Bodybuilders have been doing preacher curls for decades to build a bigger biceps peak.
The incline dumbbell curl is a much better exercise for building the biceps peak than the preacher curl.
VERDICT: INCLINE DUMBBELL CURL
Since the long head of the biceps makes up the majority of the biceps peak and the incline dumbbell curl better targets the long head, the incline dumbbell curl is the better exercise for maximizing the biceps peak.
Although the shape of your biceps peak is somewhat determined by your genetics, you build more mass on your biceps peak to make it more impressive. To focus more on the biceps peak, include incline dumbbell curls in your training.
Do them early in your workout, such as at the very beginning or following the major biceps mass builder — barbell curls. Of course, you should also include preacher curls in your training to work the short head of the biceps for better balanced biceps development.
