Set-up: Grasp two parallel bars at approximately shoulder width. A machine appartus may be used to provide assistance and make the exercise easier, whereas a weight belt will allow for external loading to make the exercise more difficult.
Lift: Begin the exercise with arms extended and descend until your upper arms are nearly parallel to the floor.
Emphasis: Only descend to parallel or beyond if there is no inappropriate strain in the shoulders. Do not lock your elbows at the end of the movement.
