Description
The Barbell Preacher Curl is a classic exercise performed on a preacher bench using a straight barbell to isolate the biceps. Unlike the EZ-bar variation, the straight barbell grip places more stress on the wrists but slightly increases brachialis activation. Having the arms fully supported on the preacher bench eliminates body sway and maximizes bicep isolation. It intensely targets the lower portion and the long head of the biceps brachii. It is a staple movement in classic bodybuilding routines. When performed regularly, it provides significant improvements in lower bicep development, isolation quality, and arm shaping.
