This is an excerpt from Fitness by Nancy Louise Naternicola.
The triceps muscle is located at the back of the arm and is used not only to straighten the arm but also to keep the elbow from moving when performing fine movements of the forearm, such as writing. The triceps muscle is also involved in pushing actions, as in opening doors. In addition, the triceps works with other muscles to extend the arm at the shoulder joint, as when holding something behind the back. Following are exercises that strengthen the triceps.
