We do not stop exercising because we grow old - we grow old because we stop exercising.
- Kenneth Cooper
Even when we are pushing ourselves, I think that we subconsciously 'protect ourselves'. I love to push myself yet I know that in the back of my mind I'm weighing just how rough a drill/exercise is going to be.
Some of the best workouts my Kung Fu school has done in a long time have been what we lovingly call Cards of Doom. What is that you ask?
We take a deck of cards and, going around the school, take turns drawing two cards. The first gives a guide to the amount / duration that we will be doing. The second determines the type of exercise. Spades are legs, clubs are arms, diamonds are abs, and hearts are cardio.
If a joker is drawn in the first draw - the student can choose any amount / duration and exercise they want. If a joker is drawn in the second, they can choose any kind of exercise they wish.
This has repeated resulted in us choosing counts / durations and exercise combinations we would have NEVER sanely chosen! It has been amazingly brutal. Just what our conditioning workouts should be!
