⚠️ SAFETY WARNING: Only practice sitting or lying down. NEVER in water or while driving. Stop if you feel dizzy or uncomfortable.
How it works:
1. Take 30 deep breaths (fully in, relaxed out)
2. After last exhale, hold your breath as long as comfortable
3. When you need air, inhale deeply and hold for 15 seconds
4. Repeat for 3 rounds

Tip: Each round, your hold time should increase as CO₂ tolerance improves.
