Technique Help From Vets?

What’s Crackin’ Fellas? I’m not new to PEing, in fact I have been off and on for a couple of years now. But now that I’m gonna make time for it, I need some advise from people who have been doing in steadily for a while. For jelqing, is it best for palms up or down? Is Hanging safe? etc. Any ”professional” help would be appreciated. Thanks.

I am not a vet but from what I know jelquing palms down is safer (lower risk of dorsal nerve damage). Hanging is safe if done right.
