Curls work the biceps muscles at the front of the upper arm, and also the muscles of the lower arm—the brachialis and brachioradial . You use these muscles anytime you pick something up, which is common throughout daily life. Doing the standing arm curl, you build strength in the upper arm and learn to use your arm muscles correctly, bracing with your core muscles.
