Fulcrum stretch

Can anyone explain or know a thread on how to do a manual fulcrum stretch? I have used the search yet I am still empty handed, any help would be much appreciated.

It is a type of stretch that can be performed in many ways. It’s not complicated really, the name says it all. The idea is to create a bend when stretching using something as a fulcrum. Some examples of fulcrum stretches would be the A and V-stretch where the hand would act as a fulcrum. Then there’s something called “sock stretches” which is basically stretching and using socks as a fulcrum, it works really well actually.

Thanks! That explains the trouble in finding it, I was under the impression that there was a specific stretch called a fulcrum.
