How to Identify the Brachioradialis
The brachioradialis is a muscle in the forearm. This muscle is important in professional bodybuilding and is most effectively isolated with hammer curls. You can make this muscle stand out by making a fist, placing it under a table in a half-pronated position and pulling up as if to lift the table.

1
Read up on Latin roots to know that "brachio" means "arm" and "radialis" means "radius." This muscle is attached to the radius in the arm.
-
2
Examine the brachioradialis to see that it flexes the forearm at the elbow, pronates the forearm when supinated and supinates the forearm when pronated.
-
3
Observe how the brachioradialis originates from the upper lateral supracondylar ridge of the humerus between the triceps and brachialis muscles and the lateral intermuscular septum of the humerus. Although the brachioradialis is most visible from the anterior forearm, it is actually in the posterior compartment.
-
4
Look at the insertion of the brachioradialis into the superior aspect of the styloid process of the radius, lateral side of the distal 1/2 to 1/3 of the radius and the antebrachial fascia.
-
5
Research the nervous system to know that the nerve for the brachioradialis is the radial nerve from the fifth and sixth cervical nerves or the deep branch of the radial nerve.
-
6
Study the circulatory system to know that the blood supply for the brachioradialis is the radial recurrent artery.
