This is an article written for Rutgers University Eskrima (Filipino martial arts).
It concerns the "Prison Workout." It's a simple workout, the burpee ladder.
It's an interesting read and it's got a good description of how to do a burpee. It also shows how you can get fit when you not only have no equipment, but are actively restricted from other forms of conditioning - sprinting, weight training, etc.
