! Even though I took it very easy during both classes, they still kicked my butt. Well, if you think about it, it has almost been a year since I have been on a six inch step. I was on 4 inches through the majority of my pregnancy and then I didn't really do much working out until my first day back to work. But I'm feeling much better today. As for sleep that night, my husband offered to be on "Eric watch" and I therefore slept like a log.
