Mid-way through a recent group exercise class, the teacher lost me.  She didn’t lose me because of some complicated step sequence or insanely long set of burpees; I mentally checked out because of a few words she kept saying over and over.  “Come on!  Get that body ready for your winter beach vacation!  Think about how you want to look at those holiday parties!  PICTURE HOW YOU’LL LOOK IN THAT DRESS!”
