CrossFit

My parnter and I have been working on our 352 Unit Plan for a couple of days now and we're starting to run out of ideas.  We chose CrossFit as our unit and we want to keep the activities fun and interesting but also have it be a quality workout for a high school physical education class to do.  Does anyone have any interesting ideas or fun workouts they do for crossfit?  We've been setting up most of our lessons as stations but we want to switch it up and have something that the whole class can do together.  I guess we're looking for a crossfit game or team activity.  If anyone has any ideas I would love to hear them!
