Brachialis Muscle:
Lower Biceps Anatomy & Exercises

Find out all about the brachialis muscle, including its anatomy, how to train it, and more.

It is located on lower part of the upper arm. Specifically, it is found underneath the biceps brachii (i.e. the biceps) and extends out on both sides of it. Thus, it is also referred to as the "lower biceps" due to this location.

It is similar to the biceps not only in terms of proximity, but also in terms of function. It, too, is responsible for elbow flexion. Although, it is more active when the arm is isostatically flexed (i.e. tensed, but not moving).

There is a glossary resource at the bottom of this page, which contains definitions for all the terms in this guide.
