How to cancel Best Fitness by mail
Start with your account details
Best Fitness will look your account up from what the letter says, so check your membership number, the home club you joined at and the name on the membership agreement first.
Set out the request
Your Postbye letter to Best Fitness asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Best Fitness”. It comes from our English template.
Send it by certified mail
Send it certified to Nashua, United States, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the proof of delivery
It shows the date Best Fitness received your letter. Check your next statement: no Best Fitness charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Best Fitness, check these
- Annual fees and monthly dues are sometimes billed separately. Ask for both to be ended.
- A home club can have its own rules. Name the club in the letter so the request is not bounced between locations.
- Freezing or pausing a membership is not cancelling it. Say clearly that you want the membership ended.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a gym or fitness membership
Gyms often require written notice, set a notice window before the next billing date and can tie the cancellation to the home club, so a dated letter is the record that counts.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
