In one line
A forearm flexor that flexes the elbow and both supinates and pronates the forearm.
Detail
The brachioradialis (Ellison, 1991) has the functions: (1) flexion, (2) supination, and (3) pronation. A neutral-position hammer curl brings the brachialis and brachioradialis into play. It contracts (with the biceps brachii and brachialis) during elbow flexion.
Key facts
- Functions: flexion; supination; pronation.
- Engaged by the neutral-grip hammer curl.
Connections
- biceps-brachii — elbow flexor alongside it.
- brachialis — co-engaged in the hammer curl.
- supination / pronation — its forearm actions.
- hammer-curl / reverse-curl — training exercises.

Biceps BrachiiClosely related
The strongest flexor of the elbow joint (long and short heads); flexes the elbow, supinates the forearm, and weakly flexes the shoulder; a 2-joint muscle (ROM 135°).BrachialisClosely related
The only pure flexor of the elbow joint; pulls on the ulna, which does not rotate.Flexion
Bending a joint so the bones come closer together.Pronation
Rotation of the forearm that turns the palm down, rotating the radius on the ulna.Supination
Rotation of the forearm that turns the palm up, rotating the radius on the ulna.Hammer Curls
Neutral-grip ("hammer") curl that targets the long head of the biceps and brings the brachialis and brachioradialis strongly into play.Reverse Curls
Pronated-grip curl that trains the forearm extensors/brachioradialis; an intermediate forearm exercise.
