Warm-up games are one of the most important parts of the rehearsal process and in the coaching class Jeff Griggs taught, this is the list the group came up with. The class spent a chunk of time brainstorming this and a lot of exercises were written down.
By the way, my notes from the class are at improvhobby.wordpress.com (without these lists) but that's where I actually do my write-ups of the classes that I take; I have to warn you though they really read like notes taken in a class. Why at wordpress? I had the wordpress blog before I had access to a website blog and I'm loathe to give it up, so instead, I'm trying to compartmentalize.
