Enzyme has already mentioned Fitness First.
I used to be a member too, until I ran out of money and had to leave. Now, I personally did not have a problem leaving: I included the phrase "a copy of this letter has been sent to my bank manager and to my soliciter" in my cancellation letter. Mostly because I googled "fitness first cancellation" to see if there could be any problems with cancelling. I found this: fitnessfirstsucks.com

Some of the lenghts that FF will go to are horrendous, and I'm actually surprised they haven't had several fraud cases launched against them yet.

I used to be a member of a chain called Total Fitness.
They were quite good. Then I moved house; my nearest TF is about 15 miles away, while Fatness First is a three-minute bike ride. There was, I thought, no competition.

Silly me. Were there another gym within a tolerable cylcing distance, I'd be there like a shot.

Yep.
And it was horrendously stinky - never cleaned, mouldy showers, hair all over the floor, deafening music, TVs that didn't work (tbh I took a book there anyway, it's quite easy to read on the cross-trainer), with broken windows.

The worst thing about it though, was the fact it gave away a free copy of the Daily Mail to every gym-goer, every day. Urgh.

Could have been worse.
It could have been the Telegraph.

I have seen all these things at FF.
*retches*

I wouldn't take a book, though: I don't think I'd be able to concentrate. Plus, people in my part of Manchester don't entirely trust those who can read and do so for pleasure.

Some of that sounds a bit illegal.

My AV
Flags that site as having bad JS Downloaders.Agents - if really harmful or not I do not know.

oh!
Ok, many apologies if it does cause problems. My AV is fine with it, but might not be as thorough as other ones.
