Best ways to warmup whole body quickly out of the pen

What are some of the best ways to warm up the body quickly as possible as a reliever?

Watch Mariano Rivera and see what he’s doing, how he loosens up prior to starting his warmup. That guy doesn’t waste any motion, he just gets into it—some good stretches to begin with, then he starts throwing, and in less time than it takes to tell it he’s ready to get out there and make batters look stupid with that cutter. :slight_smile:
