It looks like I'm the first person to like this practice, so I'm going to go for two for two and be the first commenter as well - (-; Sarah these practices are so innovative and amazing. I will come back to this core work. ThanK you!
Another beautiful practice, really felt that zipper in my core. A great way to start the day and excellent for my posture. I enjoyed the joke about New York, Chicago and LA. My kind of town! More please. Namaste.
