Hello!

I try to have some training for 2 moths with coach, and now faced a big progress but the risks is getting bigger as I see it.
I got quite a nice finning technique and good relaxation technique, so we worked on co2 tolerance, to make contractions comfortable...
For now 100m is a training distance but when I go further I found new alerts in my body.
Recently when I did 120 I found grey noise in my head, another time lack of strength... That means that contractions is not the wall, but I feel that grey noise in head and lack of strength (not lactic)... That is something that come right before the black... Could you comment it, what are your feelings when you coming to your 80% max?
What should be the next step in training...?
 
The problem is that your brain isn't going to tell you your low on O2, pushing too hard, too quick is likely to get you in trouble, if you research SWB it is often those that are making progress and pushing to their limits etc that fall foul, very often exceptionally fit people. No one could give you a symptom that will effect YOU, all bodies are different on different days, tiredness, diet, time of day, there are so many variables, that to give a symptom that you would definitely feel before blackout would be impossible and irresponsible. I would say enjoy the journey and don't obsess over the destination, meaning keep it fun and don't be in too much of a rush to get distance/depth. I myself am never going to be in a position to push my limits as I CNF in the sea, alone and in an area with strong tides. I do what I am comfortable with, am never gonna get super deep and enjoy every minute. Keep safe and enjoy yourself (y)

Get a pulse oxy meter and wear it when you do dry training. You can begin to learn some of your body's different signals.
 
I bought a cheap oxi. it's pretty tricky to use. Becase it will take about randomly 5-10 sec to power up. I also like to wipe my finger dry. If i start breathing after surfacing from hypoxia, it tends to affect the SpO2 number. So I have to keep holding until the damn thing is ready to use which is not practical. How do you get it to work?

Use it for dry training, cold water facial immersion experiments, or if you really want to use it in a pool tape a bag over your hand. You can learn a lot with dry experiments.
