How to cancel Just Fit by mail

  1. Get your account details together

    Before writing, collect your membership number, the home club you joined at and the name on the membership agreement. Just Fit can only act on a request it can match to an account.

  2. Draft the request

    Because Just Fit is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.

  3. Post the letter

    Use certified mail for the 50226 Frechen address in the next section, so the post office records the delivery. Write down the tracking number.

  4. Hold on to the receipt

    Keep the tracking record with your copy of the letter. If Just Fit bills you after the date it received the request, you have the dates to point to.

With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Just Fit, check these

  • 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.
  • Read the notice window in your agreement. A letter that arrives after the cut-off can miss that month's charge.

Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancel Just Fit

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.

Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.

For a gym or fitness membership: read the notice window in your agreement. A letter that arrives after the cut-off can miss that month's charge.

Which language is my Just Fit letter written in?
