Forearm Headstands

I struggle mightily with balance on these.   Maybe it would help motivate me if there was some listed benefit of doing them.   I keep pondering why I'm balancing on forearms when hands would build my shoulder strength and balance.   There is nothing listed on how this helps unless it's just a variation to slow us down so our connective tissue can strengthen.  Really miss the brittish guy over explaining purpose and correct form videos.
