How to cancel Activ Fitness by mail
Get your account details together
Activ 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.
Put the request in writing
Postbye writes the letter in German from our German template, because Activ Fitness's address is in Switzerland. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Activ Fitness to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Send it certified to Zürich, Switzerland, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
The receipt dates your request. Look at your next statement for any Activ Fitness charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Activ 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 mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
