what muscles do lat pulldowns work
Latissimus Dorsi. The main muscle mover in the lat pulldown is the latissimus dorsi, or lats. They are located on the sides of your middle-to lower-back. You probably recognize the lats on bodybuilders because the muscle looks like wings that extend from underneath the shoulder to the lower back.rms. The three muscles that make up your biceps -- the biceps brachii, the brachialis and the brachioradialis -- are also used during the lat pulldown. When the bicep group contracts and shortens, your arm flexes. This flexion occurs when you pull down the lat bar and decrease the angle at your elbow.
