Stand with your feet about shoulder-width apart and your knees slightly bent. Grasp water bottles in each hand with an overhand grip (palms facing downward), and let the bottles hang in front of your body. This is your starting position. Raise the bottles straight up to the level of your shoulders. Your elbows should flare out to the sides. Exhale during this movement. Lower the bottles to the starting position. Inhale during this movement. Repeat for the recommended number of repetitions.
