Supposing that, it is safe to acknowledge that particular behaviour can be created by building reward circuits and overcoming initial aversion common when building any habit.
On top of this, being physically fit generally results in increased longevity, giving you more total time to enjoy the things you do enjoy. (And enjoy them in a physically superior state.)

I think humans have a surprising capacity to learn to enjoy things (or, at least, tolerate) and that sticking with something is largely a question of overcoming an initial "enjoyment" curve. Besides, why does everything need to be enjoyable or stimulating? There is certainly value in a lack of stimulation.
I'll be physically weak and happy instead and continue to put concepts into my mind and enjoy the activity I do get, thank you.
