Wim Hof Breathing exercise: 10 rounds to reach 4 minutes of breath retention

Fill your lungs (inhale through your nose) deeper than you thought possible and then let the air out (exhale through your mouth) Inhale fully from stomach to chest to head, then let the exhale happen naturally. Listen to your body and go with the flow. We recommend practicing right after waking up while fasting, or before a meal when your stomach is still empty. INSTRUCTIONS: 1) Inhale through your nose, filling your lungs fully and exhale through your mouth, letting the air out. Maintain a steady pace and fully utilize the diaphragm. Repeat this 40 times. 2) Then let the air out and hold for as long as you can without force. Hold your breath until you feel the sigh reflex or feel an urge to breath in. 3) Inhale to full capacity.

When you are at full capacity, hold the breath for around 15 seconds. 4) Repeat this process for 10 times 5) Close your eyes, relax and go with the flow :) You may feel tingling in the hands, feet, or face.
