Muscles
Worked in Hammer Curls (Focus on Brachialis)
Primary Muscles:
Brachialis - The
main target, located under the biceps, helps flex the
elbow.
Brachioradialis - A forearm muscle
assisting in elbow flexion.
Biceps Brachii - The large upper arm
muscle, also involved in flexing the elbow.
Secondary Muscles:
Forearm muscles - Support grip
strength.
Deltoid (front) - Stabilizes the
shoulder.
Why Hammer Curls Target the Brachialis: The neutral grip reduces the role of the biceps and shifts focus
to the brachialis, making
it a great exercise for arm thickness and strength.
