One day I saw that I had been driving in reverse: I was looking for a slot in the day to “work-out” instead finding time-spaces to “work-in” and integrate my training life with my whole life.
The chief and subtle difference is that working-in assumes a lifelong, committed training life awaiting us in real time all of the time, while working-out is some kind of exceptional act we set-aside. It takes on a clunky, conditional bigness as we add conditions for the “workout” to be “right.”
Physical training and exercise, if we’re medically cleared for it, is inherently good. It is worthy of working-in at many time-space points in our day.
