Only the Account Owner for each gym will be able to change a gym subscription. The Account Owner is the person who initiated the sign-up process with CrossFit btwb. Not sure who the Account Owner is for your gym? Visit the gym admin page to find out.
A gym's subscription can be changed at any time via the gym menu in the top-right corner of the header of www.crossfitbtwb.com. Click on the subscription link from the drop-down menu that appears.
Click on the Manage Subscription link from the subscription page to see the gym's current plan and the available options. The Account Owner can also be changed.
