This is another lesson from the February series, exploring core muscles and using the breath to sense the core from the inside out. It's a recorded class, which isn't as effective as a live class, where the teacher can respond to the pace of the students. But if you're curious about the class or can't attend, this is a good sample lesson to try. Find a comfortable place to lie on your back, on a carpet or other firm, padded surface. Wear comfortable clothes and allow about an hour for the lesson. Take care and don't do anything uncomfortable. You can always make the movement smaller and slower to be more comfortable, or simply imagine it, and still get the same effect. Enjoy!
