You know that feeling when your shoulders are up to your ears and you feel like you haven’t actually taken a breath in an hour? It usually accompanies stress and anxiety. Shallow, chest breathing overtaxes muscles like the pectoralis minor, scalenes and serratus anterior and posterior as they work to elevate the ribs on inhalation. If you’re guilty of this habit, try breathing into your belly and imagine your ribs expanding laterally, anteriorly/posteriorly and superiorly.
