Stand with knees slightly bent and feet no more than shoulder width apart. Stand in good body alignment (abs tight, chest up, back straight). Hold dumbbells (palms in) in front of legs, with elbows slightly bent. Squeeze together (retract) shoulder blades. In a controlled motion, raise dumbbells up, keeping elbows fixed, until arms are parallel to the floor. While maintaining the controlled motion, return to starting position. Do not allow muscles to relax before next repetition.
