The single-arm cable seated row is a version of the cable row movement that train the muscles of the upper back one side at a time. It targets a wide range of muscles including the lats (latissimus dorsi), traps, rhomboids, and rear deltoids, as well as the biceps. The single-arm row can work well in a variety of rep-ranges, but is most popular in muscle-building workouts or as an accessory movement for strength workouts.
