Class Overview

Fully Vaxxed ClassesYou must show proof of vaccination for the first Fully Vaxxed class you take. We’ll make a note in your MindBody account so you’ll be set for all future Fully Vaxxed classes. Note that you are considered fully vaccinated 2 weeks after your last shot. For proof of vaccination you can show your vaccine card. We strongly recommend that all clients and staff wear masks indoors, even in Fully Vaccinated classes. We recognize that this is your personal choice, and encourage it for your safety and the safety of those around you. Mask Optional ClassesMasks are optional for any Fivers who are fully vaccinated. You will need to show proof of vaccination to take your mask off during a Mask Optional class. Fivers who are not fully vaccinated should keep masks on at all times in the studio, including during classes. For all classes, plz note… Everyone (including Fivers who are fully vaxxed) should wear a mask at all times in common areas. Masks are always optional for fully vaxxed Fivers. Keep it on if it makes you more comfortable! Continue to sanitize often when in studio. If you are not feeling well, have a fever, or have been in close contact with someone who has tested positive for COVID-19, please stay home! We’ll continue to be flexible with our cancellation policy.
