I’ve always loved sports; so that part’s easy, personally. But I’ve also learned to kind of savor the feeling of using my muscles and getting tired. Whatever I’m doing, or even on days where I didn’t have time to “exercise”, I make a point to check in on different parts of my body, maybe tense them or stretch; just trying to notice what feels good and then really savor that feeling. I find that building that mental practice helps motivate me to seek out exercise, or power through when I’m not really enjoying a particular activity.
