Well that was a complete and utter waste of an hour.
I worked up a mild sweat in one song, I think.
I didn't puff at all.
It was like a senior's fitness class with a lot of bottom shaking added.
The instructor's physique was fine as far women's bodies go, but not exactly an advertisement for the fat burning value of the class.
She told us we did very well and she'd love to see us back next week.
The chances are remote.
