+# Breathing Technique
+
+Deep stomach (diaphragmatic) breathing feels tight and not naturally easy — noticed Jul 23, both at rest and while running. Smoking is a contributing factor (reduced lung elasticity, tight intercostals).
+
+## Why this matters for running
+
+- Shallow chest breathing = less oxygen per breath → heart compensates with higher rate
+- Accessory muscles (neck, shoulders) fatigue and create tension
+- Can partially explain high anaerobic zone time even on runs that feel easy
+- Efficient breathing is one of the highest-leverage improvements for distance running
+
+## Smoking's role
+
+- Reduces lung compliance (elasticity) — lungs don't expand/contract as freely
+- Tightens intercostal muscles over time
+- Increases resting HR and reduces VO₂Max ceiling
+- The good news: lung function begins improving within weeks of quitting/reducing
+- Even cutting down before runs makes a measurable difference
+
+## Drills to try
+
+### 1. 90/90 diaphragmatic reset (daily, 2-3 min)
+- Lie on your back, feet up on a chair/couch (knees and hips at 90°)
+- One hand on belly, one on chest
+- Breathe through your nose — goal is **only the belly hand moves**
+- Don't force deep breaths; normal volume, just redirected to the belly
+- If chest moves more, that's the pattern you're retraining
+
+### 2. Side-lying rib expansion (pre-run or before bed)
+- Lie on one side, reach the top arm overhead
+- Breathe into the "up" side of your ribcage — feel lateral expansion
+- 5-10 slow breaths per side
+- This loosens intercostals that get stuck from forward posture + smoking
+
+### 3. Nose-in, mouth-out during runs
+- First km: try nasal inhale, mouth exhale
+- At 6'30"+ pace you'll eventually need mouth breathing — that's fine
+- The goal isn't to nose-breathe the whole run, just to practice diaphragmatic engagement early
+
+### 4. Pre-run breathing check (30 seconds)
+- Standing, hands on lower ribs
+- Take 3-4 slow belly breaths through the nose
+- Feel ribs expand sideways, not just forward
+- If it's tight, that's data — note it but don't force it
+
+## What to track
+
+- Does the tightness change over time with the drills?
+- Any difference on run days vs rest days?
+- Does it correlate with HR zones (more anaerobic on tight-breathing days)?
+- Any change if you reduce/skip smoking before a run?
