Learn the proper way to sit on a yoga mat with Yoga Instructor Michelle Adams. These tips are great whether you're getting ready to meditate or start a yoga flow. Depending on your flexibility, you'll want to settle in a position where you're sitting on your Sitz bones (or butt bones). Once you're sitting comfortably, roll your shoulders back, pull your chest forward, and lean slightly forward while lengthening your spine. This allows for proper airflow. Using tools like blocks or a cushion can help add support as you work on your flexibility.
