Building on the previous block of 3 arm positions/movements, Ron and I are adding the forward slit.

This is an asymmetrical position of the legs which helps stretch the calves, maintain alignment in the spine relative to the back leg, while applying those 3 arm movements to demonstrate how you can weave the fundamentals into a nice progression of upper and lower body movements. Explained in the book, this also goes on to become a balance exercise, by elevating the back leg, as we briefly discuss in this video.

The entirety of the moves can be studied in the Fundamental Exercises.
