I have a few questions about the reverse planche.
I do not mean a mexican handstand like this:

I mean a real reverse planche like this one:

Does it translate to a "normal" planche in any aspect?
It obviously requires flexible shoulders, but what else? Which muscles are involved?
How do you train for it?
What are the progressions?
And is it easier if you straddle, like in this picture?: http://i.imgur.com/2miQuaw.jpg
Not considering the necessity of flexibility - how hard is it? Is it harder than a normal straddle planche?
I am very curious! Thanks in advance!
