Chin-ups, like most pull-ups, target the latissimus dorsi muscle of the back 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.
SHARE SHARE TWEET EMAIL. The primary muscle worked by the lat pulldown is the latissimus dorsi. This muscle is a large fan-shaped muscle that spans from rmiddle of the back, wrapping around the side and covering part of the lower three ribs.llow at least 24 hours of rest time after using the lat pulldown machine. Anytime you lift weights, your muscles are actually tearing apart and breaking down. During the rest period, they heal and build themselves up stronger than before you did the workout. That is how muscles gain strength, during the rest periods.
