Paddy23, I wish you good luck. If you decided risking your life for nothing, when there is no reason for improving your performance in such way, it is your choice, but please avoid advising other beginners such hazardeous techniques. There are plenty of other safe ways how you can learn relaxing and knowing your body reactions during apnea and there is absolutely no reason why you would need learning relaxing at depth in the sea (and alone).
There are plenty of young people who died exactly doing that - and often they were just at the bottom of a pool while a life guard or a friend was informed - at freediving training such security is simply completely insufficient. Look for example at this thread:
http://forums.deeperblue.net/safety/...ht=sweden+died but there are regularly such cases being reported here on DB, and there are even many more of them in reality.
The pool bottom or the sea is really not a place for such solo training. So please avoid advising it to beginners who may take you for serious, and may die stupidly. Those who want to improve their performance, please get an experienced buddy, join a freediving club, pass a freediving course, or learn and train dry, but for the sake of your life, do not try improving your performance in water alone. The sea is beautiful for diving and exploring it, but not for trying to beat your personal bests solo (and dying solo).
Paddy23, call me rude, but I still consider your advice unwise, stupid, reckless, and completely irresponsible.
