Lie face up on bench. Place feet flat on floor. Keep arms perpendicular to the floor with dumbbell locked in hands. Keep elbows fixed, maintaining a slight bend. Stay in good body alignment (abs tight, chest up, back straight). In a controlled motion, keeping elbows fixed, begin lowering arms over head. Avoid lowering dumbbell past head. Stretch lat muscles to a comfortable position without compromising form; avoid excessive arching of the low back. While maintaining the controlled motion, contract lat muscles and return arms to starting position. Do not allow muscles to relax before next repetition.
