Before you cancel Mad Muscles, check these

  • 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.
  • A home club can have its own rules. Name the club in the letter so the request is not bounced between locations.

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

Cancel Mad Muscles

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.
