Medicine Ball Routines?

[purple]

I've been looking for something thats a bit different and came across a couple posts elsewhere about medicine ball workout routines. Has anyone used these in the past or currently and can suggest something thats nice and specific for track?

I've used them alot for core training. Not as much other things or since I got a different coach who doesn't think they help much. I think they can be rather dangerous if you don't get proper supervision while learning how to use them.
