Your body is a tool. Working out, exercise, training, whatever you want to call it. It's all to refine, redefine, and develop this tool. It is a means to a greater end, not an end in itself.
If you are not able to meet the physical demands of your life you will never even scratch the surface on all the things you want to accomplish.
Health first, world domination right after. (And by world domination I obviously mean providing the most value and service possible so we can all crush it together).
