gigi_xo, I can so identify with what you're saying.
I'd say that it's not that I hate exercise per se. Instead, I hate any activity that forces me to attend to details... especially details regarding my body. And, I feel a little out of the norm when compared to my ESxx friends who are so into their physical activities. And this makes sense because my inferior function is Si (Introverted Sensing) and Se (Extraverted Sensing) isn't even on my map.
When I have enjoyed physical activities such as hiking, mountain biking, cycling, and even golf, I approach it very differently from my S friends. I get into the idea of a sport. For example, after I saw the Legend of Bagger Vance (which is a retelling of a story from the Bhagavad Gita) I finally "got" golf. So NFs can "get sports" but on their own, big picture terms.
Finally, ENFPs and INFJs have a harder time of it than ENFJs and INFPs. With our dominant iNtuition, Sensing can be very underdeveloped.
