Don’t interrupt classes by going late or leaving early. If you need to leave early, stay in the back of the class so you can quietly slip out; and be sure to inform the instructor at the beginning of the class if you need to leave early. Don’t get too close. If there are several machines on either side of you, don’t get on one right next to another person. If you are putting your mat down in a class, give the persons around you room to put their mats down and be able to move during the class.
