Chin-Ups: Targeting the Dynamic Duo of Back and Biceps

Chin-ups, like most pull-ups, target the latissimus dorsi muscle as a shoulder extensor, scapular downward rotator and scapular depressor, in bringing the spine to the humerus. This is assisted by elbow flexors (brachialis, brachioradialis, biceps brachii) which bring the humerus to the forearm. Chin-ups unlike pull ups also highly target the biceps.That is one of the main differences between pull ups and chin ups.
