|Utility:||Basic or Auxiliary|
Kneel over side of bench with arm and leg to side. Grasp dumbbell.
Pull dumbbell up out to side with upper arm perpendicular to trunk until upper arm is just beyond horizontal. Lower and repeat.
If upper arm travels closer than perpendicular to trunk, latissimus dorsi becomes involved. Elbow should be raised dire ctly lateral to shoulder. Positioning torso at 45° is not sufficient angle to target rear deltoids. Keep torso bent over approximately horizontal. See side view of Dumbbell Rear Delt Row. Much lighter resistance is required as Dumbbell Bent-over Row.
