Latissimus Dorsi

The latissimus dorsi receives particular emphasis during the short-seated cable pulldown. The lat generates maximal force when the distance between its upper and lower attachment ends is minimized. The lat's primary action on the humerus is internal rotation, which produces the characteristic wide, internally rotated arm carriage of the syndrome. Social and aesthetic motivations may reinforce the wide arm position, but the biomechanical foundation driving it is real. Keeping the shoulder positioned down and back during the pull targets the lats effectively.
