Ha. I realize that in the past they were the poster child of shitty cancellation policies (and super shitty behavior at the start of covid) , but for what its worth I just canceled my membership and it was as straightforward as could be. Didn't even have to provide 30 days notice or whatever BS is standard with gyms to keep you on the hook for one additional month.

For reference there are requirements of how you can get out of a gym membership https://www.mass.gov/service-details/making-health-clubs-work-for-you
