I know the question is fairly vague and I apologize but I've honestly never even touched the silks. But I really want to learn to use them. I think they're beautiful and elegant and powerful. And I also believe that they would help me get over my fear. However, I have a few things holding me back-

I have a fear of falling. Not of heights. Of falling.
Which wouldn't be that big of a deal but I don't have much upper body strength and am not sure that I would be able to even pull myself up- and if I did if I could stay up and- yeah know- not fall.

So my question is this: What should I do to prepare myself to use Aerial silks? Should I train to build up my strength? Or, as I once read, should I just go for it and hope everything works out? If I should train, what kind of exercises would best prepare me?
