Sweating in Orlando

I'm in Orlando for work, and took a step Jazzercise class this morning. I realized that my step teacher in VA is a kick-butt and take-names kind of gal! If I had kept the pace that the Orlando teacher set, I would have barely broken a sweat... And half the class left before the strength training! I have a new found respect for even the slowest ladies in my classes back home; they ROCK!
