1) Inhale and pull your arms back by pulling your scapula (shoulder blades) together.* Again, do not let this move effect the rest of your perfect posture -- your ribs are down, your shoulders are down, and your neck is long.
2) Exhale and return your shoulders to neutral.
Repeat this exercise 3-5 times. You want to get a good inner sense of what each position feels like. This will enable you to make quick corrections and increase your shoulder stability as you exercise.
