(Arturo video note : Video is of a drop back. While I'm in UD I start thinking about tic tocking. I think for a moment and then do a UD with my feet on the sofa, as in the picture, and see about kicking back over one leg at a time. Doesn't feel quite right yet so give up on it for now. The Youtube video below is of someone doing the same thing, kicking back and forth off a half gymball).
Thanks to Anon. in the comments section or sending me the link to this. Yes this is what I was trying to do, thought it made sense. Not sure I'd trust the half gym ball though, think i might miss it.
