Rotating Triceps Kickback

Stand with your knees bent and lean forward slightly, with a dumbbell in each hand. Bend your right elbow to bring the dumbbell to your side, making your upper arm parallel with the floor. Press the dumbbell back, and as you straighten your arm, rotate it so that your palm faces the ceiling. Rotate it back so that your palm faces in, and return your arm to the bent position. Do 12 to 15 reps with each arm.
