Monkey Rows are a shoulder exercise that primarily affect the side delts and a bit of the rear delts. You can use more resistance than lateral raises. It's a great exercise.
Hold a DB in each hand at your side in a neutral grip. Raise the DB's along your side as straight up as possible as your elbows bend outward and as forward as you can make them. Lean a bit forward from the waist. Raise the DB's toward the armpit as high as you can and then return to starting position.
