How to negotiate a better deal with the gym?

I'm thinking about rejoining a high-end gym (that belongs to a
national chaine) after a two-year break, and they're still quoting the
same membership fees as they had at the height of the tech boom
(they're still waiving the initiation fee, same as before).  I know
they have considerably fewer members now, and
would like to leverage this to my advantage. 

Both my husband and I would join, so I think this should be pretty
attractive to them.  I would be interested in a monthly membership at
an annual rate since it is more flexible regarding termination.

The membership officer won't budge. I do like this gym as they offer
classes I want, but it's quite pricy.

Any tips?
