The main reason I like the Deck of Pain method, I think, is the randomness from a shuffled deck of cards. With nearly all other methods of exercise, I'm always counting down the miles/reps/laps/minutes, etc. But with the randomization, I only know the number of cards left and have no real idea what the next card holds (until the last one, I guess). Often, I'll shuffle more than one deck of cards and then just do 52, with the other half ready for the next workout. That way, I can have 'hard' days with some exercises and easy ones, further randomizing things.
