Heh...
Was that spinning? I've heard that can be a series workout.
I've thought about doing some sort of fitness class one of these days - during the winter, at least, when its hard to do much outside. On the one hand, I hate to leave the house. On the other, if I'm paying for something, I'm more likely to actually *do* it.
I don't know if I'd know the difference between cycling and spinning. It was 45 minutes of a hard ride. I kept going, just not at the pace she was leading.
