I may be off the mark but I remember scenes from the movie
_Flashdance_ that, although she was a dancer ("erotic"dancer, I suppose)
there was at least one scene depicting her as a hardbody.  "She" was
played by Jennifer Beals (where is she now ??).  When I see (or hear)
the term "aerobics" that is always the first scene to come to my mind.
