You can practice plenty things:) but the thing is that is not those things works, but a practice :) you can make the breathing technique practice all wrong way, but one day it will work, because you PRACTICE!!
If you train in low oxygen condition(mountains) you get down to impress everyone in high oxygen conditions, and you won't need any magic breathing technique. Because you have no time fit in case the truck is running on you :)
Also, it takes practice to get the technique the right way.
Is not something you can do for the first time and do it the right way.
Yes I know that :)
