I normally go circuit training on a Monday evening but it's not on during August, hence the zumba replacement. But let me tell you: it cost £4 each and there were 49 women there (no, sorry, there were 48 women and 1 lad).
Even allowing for hall hire it was a nice little earner, as Arthur Daley would have said.
Next time I go I must remember not to wear my usual exercise clothes. Lots of the women there looked like J-Lo; I bore a closer resemblance to Eric Morecambe.
