37. Perfect Posture
Granted, this isn't exactly an exercise.

And yes, you can practice with a book on your head if you need to!
You can also practice good posture while you're sitting in your office chair at work.
In fact, if you keep yourself from slouching at the office, it can even help your productivity.
