When most people think of arm strength, they think of biceps. However, targeting your triceps muscles is equally important. Understanding the anatomy of these muscles will help you train your triceps effectively. Learn how to target each head of the Triceps Brachii so you can hit your next arm day with the tools to build upper body size and strength.
You’ll notice the triceps brachii covers just about the entire backside of the arm and has two prominent heads, the long head and the lateral head. These can be seen fairly easily. However, there is a third head to this muscle that is found below the two superficial heads. This is the medial head, shown in green.
Each head of the triceps muscle contracts and shortens to pull the forearm into extension. This is the main function of the entire muscle. However, to strengthen each head of the muscle, we can take a closer look at their anatomical differences.
Medial & Lateral Heads
These two heads originate on the backside of the arm bone and attach at the base of the forearm. They are at full length when the arms are kept down at the side, such as in a Triceps Pushdown.

This head originates higher up on the scapula and attaches at the base of the forearm. Because of its high point of origin, this part of the muscle is at full length when the elbows are positioned overhead, such as in a overhead triceps extension.
