A Couple of Questions (and pre-emptive apologies, because I'm sure they get asked a lot here!)
Basically: With practice, how long might one expect to be able to increase your static breath hold?
Some maybe relevant information below...
About 15 years ago I went on a one day 'Intro to Freediving' thing. First half in a classroom learning breathing/meditative techniques, then the afternoon in a pool.
Fast forward to the beginning of this year, and I decided to see how long I could still do a static, dry, breath hold for; i.e. lying on my sofa in the dark. And was slightly surprised that even though I'm considerably less fit now, and had been a fairly heavy smoker for almost all of that time, it was still around about 4.5 mins.
In short… I do already know about breathing techniques, and I'm coming off what I imagine is a relatively high base level*. So given that, what do people think might be a reasonable goal to aim for, after some proper practice? I was thinking of maybe doing a couple of holds per day, and trying to increase the length by maybe 20s per week, if that sounds reasonable?
(FWIW I've been free and scuba diving since a fairly young age. So want to do this both cos it's useful for that, but mostly actually just because I enjoy it. I find static apnea both relaxing, and then also quite exhilarating afterwards, in an endorphin-rush kinda way.)
* I suspect just because I'm quite broad-shouldered, and consequently probably have quite large lungs (?).
