Some people take better care of their car than they do of their body. Most people, in fact, pay little attention to their body until something goes wrong. Yet why create that kind of situation? Look at what you are eating. How much and how often do you exercise? When was your last check-up? Are you treating your physical vehicle as if it is divine? Good for you if you are. If you aren't...why not?
There is no free will if to exercise it in certain ways produces punishment. That makes a mockery of free will and renders it counterfeit.
Honor your body. Keep it in good shape. It is the most important physical tool that you have. Exercise is the meditation of the body. It allows you to feel Oneness with all of Life.
