Hyper mobility :(

I am hyper mobile particularly in my fingers. I can’t do any fingertip stuff because this happens:

My fingers just collapse into that. Even in Day 1 of YWA doing “spider fingers” in a seated position that’s how I end up. I usually default to my palms but in certain positions that basically shortens my arms and I run out of space. For example in a lunge I can’t support myself with my fingertips at all and if I go to my palms my knee is crammed into my chest.

Does this happen to anyone else or are there instructors with advice for me? I’ve kind of resigned myself to it, but I am also frustrated by it. It doesn’t hurt to have my fingers bending back but it isn’t comfortable and I can’t really support much weight.

Should I just keep some blocks handy for length and avoid finger tips? Any other clever thing I can do? I don’t think it’s worth trying to build up strength in my fingers, I’m 42 and this is how they have always been. I didn’t know it was unusual until I was about 12.
