Stepping it up?

Ok, so I'm in this mode of really wanting to see the weight start coming back off, so I'm trying new things.
I figure - hell, I can touch my toes now. I bet I can do step aerobics!
hahahahahahaha.
It must have been funny watching me try to keep up in that class.
I'm just going to blame it on losing my sense of balance and my center of gravity since losing so much weight.
That happens, right?
That just has to be the reason I stumbled around in that class, practically tripping over myself, not to mention unable to keep up with the pace or remember the routine.
But so what. I did it anyway. I took that class and I kept moving for 30 minutes even when I wasn't moving the same direction anyone else was.
