Once you understand the anatomy of the triceps brachii, you will be able to realize why you can not simply perform french presses and overhead extensions till you are blue in the face and expect to achieve complete, balanced tricep development. The medial and lateral heads originate on the upper-arm bone and attach on the ulna, which is one of the forearm bones, the long head originates on the shoulder blade and travels down the back of the upper-arm bone to attach on the ulna.

The medial and lateral heads are recruited only by movements at the elbow joint, and the long head can be recruited by movements occurring at both the elbow and shoulder joints. What this basically means is that to fully stretch the long head of the triceps, you must raise your upper arms over your head, and such as in exercises like lying french presses and overhead extensions. Pressdowns and dips train the lateral and medial heads of your triceps. You need to understand this if you are looking for muscle building.  

This movement involves facing a cable stack and grasping a handle attached to a high pulley. In the start position, your arms should be bent roughly 90 degrees so that your forearms are parallel to the floor. Press down on the handle and extend your elbow joints until your arms are straight or nearly so and flex the muscle hard. Bring the handle back to the start position under control and repeat. 

There are many variations of the pressdown. These are great tohave in a good arm exercise program.  Two-arm pressdowns can be performed with numerous handles, including the EZ-bar.
