How to cancel 3T Trening by mail
Collect the details you need
Put your membership number, the home club you joined at and the name on the membership agreement in front of you before you write: the request to 3T Trening is only as good as the details it quotes.
Prepare the letter
The request is prepared in Norwegian (template no), under the subject line “Emne: Forespørsel om oppsigelse – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send it by certified mail
Use certified mail for the 7075 Trondheim address in the next section, so the post office records the delivery. Write down the tracking number.
Keep proof the letter arrived
Delivery confirmation is your evidence that 3T Trening was asked. Watch the next statement or two for any further 3T Trening charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel 3T Trening, 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.
