Group Fitness Etiquette

Be on time for class or be early.

Must book on the rac app to attend class. Be on time. Pick a decal to stand on for physical distancing. Refer to instructor for equipment cleaning procedure. Will need to check out equipment prior to any Yoga, Mat Pilates, and Barre class. Silence cell phones. Follow modifications for easier or harder work out. Enjoy!

Appropriate clothing and no bare feet.

You should be comfortable in your clothes and they should not restrict your movement. No open-toed shoes, or bare feet allowed, except in BODYBALANCE where the use of a mat is required.

Save “chit-chat” for before or after class & silence your cell phones.

Not only is it courteous but becoming a distraction might prevent you, or someone else, from hearing important instructions. Please leave cell phones in the locker rooms.

Choose a spot in class that works for you.

If you are new to class, resist the urge to hide all the way in the back of the room – you won’t be able to see the instructor clearly. Instead, find a spot in the middle – comfortably behind experienced members but able to see what is going on.

Instructors welcome feedback after class.

All of our instructors are very interested in your ideas and questions but as a courtesy its best to wait until after class.

Follow instructors’ modifications for an easier or harder workout.

If the class isn’t going the way you anticipated, please resist the urge to start doing “your own thing” during class without first consulting the instructor.

Return equipment to appropriate space after use.

Please put your BODYPUMP equipment and dumbbells back in the appropriate area, stack like BODYPUMP plates together, stack benches against the far north wall and bands back in the cabinet.
