Ever feel like you can’t take a full breath in…no matter how hard you try? That sensation isn’t in your head. It’s often a mechanical problem caused by overactive inhalation muscles like the scalenes, sternocleidomastoid, pec minor, and upper traps. These muscles are meant to assist when you’re gasping for air, not to do the heavy lifting during every breath of your day. But chronic stress, trauma (mental or physical), posture changes, and even underlying health conditions can cause your nervous system to default into shallow breathing. Over time, your body forgets how to relax and use your diaphragm properly. The result? Your accessory breathing muscles become tight, inflamed, and hypertonic. This mechanically pulls your ribs up and out, restricting rib mobility and reducing rib cage expansion. You feel like you can’t inhale deeply. I hear it every week: “It feels like someone is sitting on my chest.” When I release these muscles and decompress the rib cage, patients often say, “Oh my God, I can finally breathe again.” And that relief isn’t just physical, it’s neurological. You’re reducing nerve compression, especially in the thoracic outlet, where tight scalenes and pec minor can irritate the brachial plexus. Symptoms I often see: 🔸Tension headaches 🔸Migraines 🔸Dizziness 🔸Chest tightness 🔸Nerve pain in the arms or hands 🔸Postural collapse and neck pain To restore balance, you need to activate your expiration system: the internal obliques, transversus abdominis, and pelvic floor. These stabilize your core and allow your inhalers to finally shut off. Here are 3 no-equipment, at-home exercises: 1️⃣ 90/90 Wall Breathing Feet on the wall, knees and hips at 90°. Exhale fully through your mouth until ribs drop. Pause. Inhale quietly through your nose. Repeat for 5 minutes daily. 2️⃣ Side-Lying Open-Book Breathing Lie on your side, top knee bent over a pillow. As you exhale, rotate your top arm open. Feel ribs expand. Add deep nasal inhales and long mouth exhales. 3️⃣ Bear Position Breathing On hands and knees, lift knees 1 inch off the floor. Exhale hard, engage your core. Inhale slowly through the nose without losing rib position. Reset the breath. Reset the nervous system.
