Position when partial hanging?

[lost in my mind]

I'm sorry if it has been asked already, I tried to look for answers but couldn't.
How do you position yourself when partial hanging? And how Do you practice on it?

I think you should lean forward, putting pressure on the rope, stay like that for sometime then quickly get up and then you black out

You can lean forward or backward or lie down or you can go down on your knees.
