Traditionally, this style of bar is used for exercises that work smaller muscle groups such as your biceps and triceps. In addition, it can often be used in place of a standard barbell when needed for exercises such as bent over rows. A curl bar allows you to use an underhand grip with your wrists slightly supinated, or turned out. Alternately, you can also use an overhand-based grip on the curl bar with your wrists slightly pronated, or turned inward. As a result, you can target the muscles of the arm and upper body dependant on the style of grip used.
