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.
Bicep curls are when you hold a dumbell, arms by your side, and bend your elbows, lifting the weight towards your shulders. Your lower arms should not move, and y â¦ our elbows should point down.
