They have kickboxing workouts, pole dancing workouts, military boot camp workouts, and prison workouts but I don't think the fitness experts have turned to the criminal world for inspiration. I imagine a Breaking and Entering Workout where participants learn how to move stealthily, climb improvised ropes, break through doors and windows, and sprint wildly for their lives under extreme time pressure. The instructors would be chosen for the depth of their first-hand knowledge, on either side of the penal system, and music would be chosen from among the vast assortment of caper film soundtracks, punctuated by loud alarm sounds when a student muffs one of the moves.
The students would have to sign a statement beforehand pledging that anything they happen to learn in the course of their instruction would be used only for good, not evil. Maybe they should be fingerprinted as well, just to be safe.
I decline to discuss specifically how this idea came to my mind today, but just wish to mention that I am sometimes very glad that I do take the time to try to stay in shape.
