Before you cancel 80 20 Endurance, 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.

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.
