As the lights dimmed, the instructor that today was going to be a Spiderman 3 class. Two plasma screens came on and played the movie trailer. One lady got up and said, "What the heck is this all about?" and left. Then the class began with the usual instructions to speed up, to slow down in certain parts, and as the group pumped away, silent interview clips with the Spiderman 3 stars played on the twin monitors. Music from the movie pounded in the background.
