I used to exercise a lot. Hiking, skiing, bike riding, etc. I was in great shape, and I had excellent stamina, but I’ve never experienced the endorphin “feel good rush” that people talk about. If I had a “rush” at all, it was just a second wind, which I experienced as not being as tired while hiking.

One of my daughters has the same experience with exercise, and not surprisingly she hates it. I don’t hate it, but I certainly don’t exercise for the endorphin rush, “feel good experience,” or whatever.

Can anyone explain what’s going on?
