How to write Gym Membership Cancellation letter

First of all you should not be going against any contract you signed or any local laws. If you signed a contract that states that you are tied to their gym for a year then there is no way you're getting out of that membership until after you paid your 12th membership monthly fees and other fees stated on your contract.

However, if you no longer owe the gym anything and you simply want to get out of it and you want to do it nice and clean then start with a formal letter stating that your concern like the following (I had to get help from my dad to make it sound clear and professional):

2010 March 11 [this is the date you'll give your letter]

To: [Name of Gym] Membership Department

Please consider this as my formal notice to terminate my membership with[Name of Gym] effective immediately.

I have been a member since [start of your membership which is often on your gym ID] to date thus fulfilling the minimum four (4) months requirement.

In view of the above, please stop charging membership fees and other charges to my credit card account starting on the month of April 2010 and beyond.

Thank you.

Make 3 copies of such letter. When you give one copy to the gym, make sure that you have one of their staffs sign your two copies. By "sign" I mean:

Received by:

[Printed name over signature]

Data received

That's proof of when you actually wanted to terminate your contract. Next step is to get them to sign your membership cancellation.
