How does Dr. Pang's Zhan Zhuang differ from Master Lam Kam Chuen's Zhan Zhuang? What difference does turning the toes inward make? My IT band is way to tight for that. Master Lam discourages the visualization of moving energy, but in 3 Centers one is to visualize energy entering through the head, hands, and feet then going into the lower dan tien.
