Heehee, mine is like that too. Yoga-jazz-interpretive-free dancing-um-er-dancing class. I mean, what makes it hard to pin down is what keeps my easily bored self involved after seven months. My teacher is the same way - of the three teachers in my neighborhood (yes, I am lucky), she does the most strenuous, most varied routines. And lots and lots of free dancing, which I've learned to love.
That's how I landed on belly dancing/kickboxing. With all the dipping, undulating, and kicking about we do, it seems the best fit. And hey, my jeans are loose, so I'm not going to start complaining now!
