Positioning the Body for Arm Curls. Mike Harrington / Getty Images. The arm curl or biceps curl is a highly recognizable weight training exercise that utilizes dumbbells or barbells, or even kettlebells, to work the muscles of the upper arm, the biceps, and to a lesser extent, the lower brachialis and brachioradialis.
Variations on this theme include: 1  concentration curl where the elbow is braced against the inside of the knee. 2  preacher curl where the elbows rest upon a sloped bench. 3  prone-body incline curl performed lying prone on an inclined bench, where the force of gravity holds the upper arms in front of the trunk.
