I am doing the Wim Hof breathing technique now around 1-2 month‘s. In this period I never pushed myself to hard in trying to get further and deeper by holding the breath longer. I wanted to fully enjoy it, this shouldn’t be a race or a fight. I‘ve found a good flow and now I can learn how to going in deeper. Today in the third round i silenced the Wim instructions and turned my timer on just to see how long I can go by now in complete peace. I heard my blood flushing through my veines, my heart pumping the blood, and then around 1m and 50sec, I guess, went everything silent. I think I did 2m 10sec. Awesome ! Have a good day and keep breathing !
