Maintaining physical fitness is more than just a good idea. It is crucial to overall well being. The mind/body relationship influences each other. When one is healthy, the other is likely to be healthy also. The hard part is maintaining a healthy balance. This takes some effort.

We are not continually up to that effort. Sometimes we may need to take to back off a bit so that enthusiasm is preserved. I think of this situation as akin to taking rest days to prevent over training.
