Hi to everyone i am doing static apnea breathold training since 3 years and may best breathold time wasl 5.10 minutes(HARDLY), and i have read some posts about empty lung training so i decided to try it out.Today i did 5 empty lung breatholds the first was 40 seconds and the last one was 2 minutes,and after that, i did a full lung breathold and i got suprised with the result.My first contraction come up at around 3.15 minutes which was coming around 2.20 and my breathold time was 5.50 without forcing myself.If i had forced it further I would be able to make it even over 6.00 minutes but i concerned that something was wrong and i stopped it.So what do you think about it??if there is someone that have done it before i would be happy if he writes his expirements.Thanks in advance
