Directionally Challenged

It's a very good thing that  I have a hard time telling my right from my left.  The woman who leads my workout video starts out calling her left her right and her right her left (so as to be telling US who are mirroring her what we should be doing), which would be confusing enough.  But half way through the video, SHE gets confused and reverts back to her own left and right.  And then she gives up and says, "the other side"!  (But it really is a good video other than that!)
