Training the brachialis muscle, a smaller muscle behind the biceps that acts as the primary mover of elbow flexion, can help to make your arm muscles look even bigger.

The hammer curl arm exercise targets your brachialis muscle, which helps to male your arms look bigger. Here's how to do the move with perfect form.

To fully develop your arms, you need to target the entire muscle group: the long and short heads of the biceps brachii, the brachialis (your elbow flexor), and the brachioradialis (forearm muscles).

This is due to the functional importance of the muscles that act on the joint, especially the brachialis, which participates in elbow flexion, and the triceps brachii, which participates in elbow ...

Researchers aimed to assess the forces exerted by elbow flexors in addition to the thickness of biceps brachii and brachialis muscles. For a comparison, they used the results from a similar study ...

However, hammer curls also emphasize two other arm muscles: the brachialis, a muscle beneath the biceps brachii that helps support the elbow joint, and the brachioradialis, a forearm muscle that ...
