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.
The triceps extension is performed while standing or seated, by lowering a weight held above the head (keeping the upper arms motionless), and then raising it again. It can be performed with both arms, or one arm at a time. This is an isolation exercise for the triceps. It is also known as the french curl.
