It depends. Running and lifting I enjoy the results but the activity is boring, I never got runners high.
Jazzercise was fun fun fun though, any sort of dance aerobics like that is perfect because have to pay just the right amount of attention to it - enough that I can't think about other things, but not so much that I really have to think hard about the movements. I wish there were still classes by me.
Yoga is fun too, in a different way. It takes concentration, always adjustments to posture, and it's very empowering to be able to do handstands or other arm balances, it's challenging in a good way and the reminders to coordinate your breath with movement is helpful.
So for me it depends on what the workout is but sure, I like moving physically, enjoy it and don't do it only for results.
