Are guests actually wearing masks? I really don't want to go if there's people not wearing masks.

Hi Bunn. Members and guests are NOT required to wear a mask while actively working out but must follow all local or club-specific restrictions. If you have any questions related to the mask policy at your home club, you can always request to speak with club management.

Some are, but most aren't. State requirements say that if you're working out then you don't have to wear one
