This is a concept that I teach quite often as a way to monitor through the foot. I learned the technique in a tai chi for balance class. This is another production by Will Stewart of 3D Optimal Performance.
This is part 2 of the series where I demonstrate the concept of EdgeWork as applied to the foot and ankle. Once again produced by Will Stewart of 3D Optimal Performance. In case you missed it, here is part one.
Special thanks to Will Stewart at 3-D Optimal Performance. Will produced this video and did a great job.
