Once you're reserved for class, cancelling your reservation is easy.
> On your app, find the reservation.
> You can swipe left on the class you reserved and it will pull up a Check-In or Cancel option.
> Click Cancel.
The gym may have reservation and cancellation policies which may prohibit you from registering and/or cancelling in a certain time frame before class. Please contact your gym admin for those details.
If the gym does not offer self check-in, you may just see Cancel upon swiping left.
