Gym ▸ Managers & Staff. Choose the type when you add someone — manager, instructor or front desk — and they start with sensible permissions for that role, which you can then adjust per person.
Staff added as instructors can appear on your public site. Website ▸ Instructors controls the order they appear in, whether each one is shown, and how their rank is displayed.
Front Desk is a full-screen check-in view for a tablet at your entrance. Staff with front-desk access can run it without reaching the rest of your admin.
