Similarly, I've never enjoyed exercise. I used to cycle to and from school every day, about 6 miles, fairly high intensity (due to my laziness, I'd start late). My aerobic capacity was certainly higher then; I could run for perhaps 30 minutes, where I'd hazard a guess that I'd be out of breath after 10 minutes now. I'm not overweight, have no difficulty walking, jumping, running, climbing hills etc. when I get the occasion to on vacation and such. But the thought of actively exercising fills me with weariness. Not enjoyable.
What I'm getting at is that I have a lifestyle that I massively enjoy, and it took a lot of experimentation and experience to discover the things I like best. Whether it is specifically healthy or not is secondary, by a long way, to how enjoyable it is.
