Mainly because the Brachialis crosses only the elbow joint, and originates @ the middle of the anterior portion of the humerus. Right where the size is desired.

tip: pronation of the hand and forearm for larger arms. Knuckles up. Isolate brachialis.
1. hammer curls
2. inverted grip EZ curl bar
3. same side to opposite shoulder hammer curls
4. pronated to supinated dumbell curls

Good start but partially incorrect. There are 3 primary movers in elbow flexion. Biceps, brachialis, and brachioradialis.
Biceps is the primary mover on palms up or supinating curls.
Brachialis plays a larger role with the palms facing in during hammers.
Brachioradialis is not the primary mover per se, but fires most intensely with pronated (palms down) grip.
*An interesting factoid is that EMG studies show that the brachioradialis fires more intensely during the eccentric portion of this move... slow down the reverse curls fellas to hit the BR for that deep forearm line that travels up the outside of the elbow.
Pronator teres is also an elbow flexor but is usually ommitted from this discussion as it plays a small role (although frequently injured).
