ADDTIONAL INFORMATION


>> Coaches are on the floor during open gyms to provide assitance and to ensure safety.  Open Gyms start with rules and general safety so all participants know how to approach our obstacles safely.

>>We understand that little bodies and big bodies move very differently.  Certain areas of the gym are set up with level/age appropriate obstacles so that everyone can train safely.

>> You can arrive anytime during the Open Gym.  If you arrive early, you will not be allowed on the obstacle floor until the open gym starts.  If you arrive late, you will still have to leave at the end of  the open gym. 

>>Pre-registration, with a valid pass or payment, is required for all open gyms.  For a discount, purchase an Open Gym 10 Pack! 

>> 10-packs can be used across all locations!  However, single visit passes purchased upon registration are for the specific locations, however, just e-mail us to switch pass over to a different location.
