Practice (with a different intention): Inviting Inspiration
Do the postures that you have decided to teach in this class. Do them the most basic way; think simple. Break it down in sequential steps. Go inside your own body to get the awareness. Decide which are the most important details. Predict which postures might be hard for your students and how you can support them with an easier version or with props. – Kripalu
