Best Classic Rock Workout Songs

I read somewhere that people who are learning CPR are often told that to do chest compressions at the right pace, they should imagine the song, "Stayin' Alive" as they work.

That got me to thinking about the more routine workouts some of us engage in, and how it seems easier to do repetitive motions to music. And that got me to thinking about classic rock songs to load on your MP3 player for your next workout. Here are some of my favorites. Take a look, then let us know which songs you work out to.

(If you don't work out regularly, be sure to confer with your favorite medical professional before you start.)
