"What is your exercise goal?"

Today, two people at worked asked me essentially the same question.  I was actually confused; isn't the "goal" of exercise to sustain and cultivate one's existence?  I was going to say "Why did Bodhidharma come from the West," but that would have been too inside baseball.

When I explained, - putting into words the best I can - "So that can exist!" one person mentioned it was very Zen, which is kind of funny to me.
