How to cancel Flexx Fitness by mail
Note your account details
You will need your membership number, the home club you joined at and the name on the membership agreement. Use exactly the details Flexx Fitness holds, so the request can be matched to your account.
Write your request
Flexx Fitness is based in Germany, so the letter goes out in German, built from our German template. Subject line: “Betreff: Kündigungsanfrage – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post the letter
Mail the letter by certified mail to the Rosenheim address in the next section, and keep the tracking number.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Flexx Fitness charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Flexx Fitness, check these
- Freezing or pausing a membership is not cancelling it. Say clearly that you want the membership ended.
- Read the notice window in your agreement. A letter that arrives after the cut-off can miss that month's charge.
- Annual fees and monthly dues are sometimes billed separately. Ask for both to be 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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
