When I was growing up, a few pieces from soundtracks from the Rocky series as well as Flashdance worked for me. In the case of Flashdance it was the title theme and "Maniac." Whatever music got you excited when you were younger can work today. Just tunes to get the blood flowing.

Just as useful is a siesta or power nap. If you can squeeze one in without getting in trouble, do it.
