A fitness habit is unnatural. We are not designed to be motivated by exercise, but by goals, fun, necessity. So, to keep up a "workout" routine is something that takes serious discipline. It is the hard way. When I was younger and had more time, I had a body you could put a muscle chart on (I did grappling sports). Yet, I'm terrible about actually going to a gym, and I eat whatever I want. I simply did what I had fun doing, was motivated by competing with others, and that was also intellectually interesting to me.
