[old version] 4 rounds Wim Hof breathing to reach 2.5 minutes of retention + OM mantra

[old version] We recommend practicing right after waking up while fasting, or before a meal when your stomach is still empty. Just follow the steps below: 1) Inhale deeply through the nose or mouth, and exhale unforced through the mouth, letting the air out. Fully inhale through the belly, then chest and then let go unforced. Maintain a steady pace and fully utilize the diaphragm. Repeat this 40 times. 2) After the last exhalation, inhale one final time, as deeply as you can. Then let the air out and hold for as long as you can without force. Hold until you feel the urge to breathe again. 3) When you feel the urge to breathe again, draw one big breath to fill your lungs. Inhale to full capacity. Feel your belly and chest expanding. When you are at full capacity, hold the breath for around 15 seconds, then let go. 4) Repeat this process for 4 times! 5) Close your eyes, relax and go with the flow! :) You may feel tingling in the hands, feet, or face.
