The concentration curl is a bodybuilding favorite for building biceps.
Some promote the concentration curl claiming it to be an exercise guaranteed to produce a bicep pump and build the mind-muscle connection.
With that said, the slow tempo typically used during the concentration curl is great for building the biceps and since it is a unilateral exercise, it helps work each bicep equally.
The reverse grip hand positioning will naturally make the biceps more involved in the exercise.
