Something I received from Yoga Journal that's so crucial....
Tell Your Teacher
Do you have an injury or a physical condition that might affect your ability to practice, like pregnancy, high blood pressure, or recent surgery? You may feel that those issues are private ones, but your teacher needs to know in order to guide you through the class safely and appropriately.
Most teachers arrive to class a few minutes early, so if you have an injury, you should, too. Seek out your teacher and ask to have a brief word with him before class. He can provide possible advice on how to approach the class, and will likely make accommodations for you during your practice.
Also, whether or not you are injured or just tired or stiff, skip poses you can't or shouldn't do, or try a modified version that avoids putting stress on the affected area. Ask your teacher if you aren't sure how to modify a particular pose. It's important to let your teacher know what's going on with you—and it's also a great way to start building a more personal relationship.
