On dual pulley seated row machine, sit slightly forward on seat or bench in order to grasp both cable attachments. Place feet on vertical platform. Position torso upright and slide hips back so knees are slightly bent.
Raise arms upward and outward to sides in Y configuration while allowing elbows to partially bend. Pull back until elbows are approximately lateral to each ear. Lower stirrups forward and downward until arms are extended straight in front of body. Repeat.
Keep torso upright throughout exercise. Stirrup is raised by combining shoulder abduction and flexion. Slight shoulder external rotation may occur with elbows bent. Front Deltoid assists shoulder flexion if upper arm angle is slightly high. Rear Deltoid assists shoulder horizontal abduction if upper arm angle is slightly low.
