Answer from a legal angle ...
You have signed a binding contract, and the gym has no obligation to change it.
Answer from a regular gym user's perspective ...
Contrary to the suggestion that gym's are hard to deal with, I find that gyms want to make their members happy, so that they ...
1. use the gym a lot, and spend more money there, and
2. tell their friends what a great gym it is.
There is a lot of competition for gyms at the mo, with national chains like David Lloyd, Fitness First, Banatynes, LA Fitness, Alive Health, etc.
Around here, we've also got Riptide, Living Well, Cheetahs, Coral, Matrix, Gym & Tonic, Dragons, etc. So gyms have to look after you or, at the end of the first year, you'll just drift off.
Go in to the gym, and speak to them at the desk. I'd be surprised if they were not willing to help you.
