Unturndown same as a turndown with straight bars though not facing back down the frame so with the straight legs it should be a unturndown. Invert is to do a knee's over the frame table where the bike faces atleast 90 degrees or more away round from you
yeah it does and "if the bikes upside down it's an invert" expalin to me the backflip then. And yes leg posistion does matter an unturndown can be put in the same posistion as an invert but of course using the straight legs to put it in that posistion where the invert is to crunchyour knee's over the frame and pull the bar through your arms...
